Power factor correction

Posted on under Installations

Power Factor Correction is an increasingly important tool in the effort to help large power consumers like factories save on electricity bills.

To increase your energy savings rate commercial electricians from Caslec would like to assist you with the installation and maintenance of Power Factor Correction units.

If your installation has poor power factor, your company’s electricity bills can be too high. A Power Factor Correction unit (PFC) can save you a lot of money by correcting this low power factor.

For commercial or industrial premises, particularly those with many inductive loads such as motors, pumps, inductive lighting or where the installation has low power factor – Caslec is here to help.

Our team of experts can use a Power Analyser to check your power factor, then design a Power Factor Correction unit with the appropriately sized capacitor steps to correct your power factor as close as possible to unity power factor, meaning you will pay less for electricity. The best news is that many of these power factor correction units can be paid for with the savings generated on your electricity bill, meaning you are not out of your pocket for the installation.

Main causes of power outages

Posted on under Tips

No matter where you are, power outages can happen anytime. That’s why in today’s blog, commercial electricians from Caslec would like to point out some major causes of electricity failures and who you should contact when such event occurs.

Nothing brings the household together quite like an unexpected electricity outage. While playing games or eating dinner under candlelights can be fun for children, power faults are no joke.

Electricity power outages usually occur without any warning and can be stressful if you don’t know the proper steps to getting out of the dark. To make things easier for you, we prepared this article, so you will know what to do when the power is out.

Common causes of power outages

  • Weather

Sydney’s weather can be a real problem when high winds or flying debris damage power lines. Torrential rains and flooding can also damage electrical infrastructure.

  • Spikes

A temporary increase in the power supply voltage can result in an electricity outage. These are usually caused by lightning strikes, tripped circuit breakers or short circuits.

  • Vehicle

Motoring accidents resulting in broken poles or causing power lines to touch can lead to an outage.

  • Bushfires

For the safety reasons, electricity supplies are often disconnected in bushfire emergency.

What you should do if there is a power outage

When the power goes out, calling your retailer might be your first thought. While your retailers sell electricity to homes and businesses across the country, they are purchasing it from the commercial power distributing companies. These companies own and operate the poles, wires, etc, so they are responsible for their maintenance.

Your retailer will usually help you to get in touch with the right people to get your electricity back; they actually can’t do as much as distributors.

Alternatively, during an outage, they can provide you with information about when the power should be switched back on.

If the outage is widespread, the phone lines could be busy with many people calling for information. In this case, electricity distributing companies often prepare pre-recorded messages offering updates on the situation.

However, if you still have any concerns regarding power outages, commercial electricians from Caslec are located in Sydney and happy to put you through with the right people!

Metering for your business

Posted on under Uncategorized

Before you start using electricity on your business premises, it needs to be metered in order to monitor usage and record consumption. Metering equipment can be purchased from the relevant supply authority like Ausgrid and Endeavour Energy and is installed at standard locations. The meter box on the side of your house or the main switch room in a high density residential or commercial premises are common locations for this sort of device.

Caslec Level 2 services provides metering services for a vast number of situations including switchboard upgrades, three phase upgrades, new installations, temporary builder’s services and supply separation.

Our services also include multi-residential properties and high-density retail developments across Sydney.

With many years of experience, Caslec level 2 service provider has secured and completed metering contract projects for many businesses in Sydney.

Commercial and industrial properties have a way bigger demand for electricity than your average domestic installation. As a result, large industrial switchboards are utilised and in turn, alternate methods. Caslec is proficient in providing metering services for facilities up to 400A for permanent and temporary supplies.

3 tips on how to find good industrial electricians.

Posted on under Tips

In today’s article, Caslec industrial electricians would like to tell you about the differences between residential and industrial electricians, so it could help you find the right professional for your needs.

You would typically assume that the rules of finding a good industrial electrician are the same for every type of specialist in the industry. In a sense, you are correct, but at the same time, it’s worth becoming familiar with the set of skills that an industrial electrician has and the type of training they undertake to get where they are in their profession or trade.

 

Industrial electricians work in specific environments and over time, either by training or through experience on the job, have distinct, knowledge of particular electrical installations and types of equipment. For example robotics and other highly specialised electrical equipment that might be used in the mining or manufacturing industry.

 

As the field of expertise is very broad, most of the industrial electricians choose to specialise in certain areas. One of the very popular in the last ten years is the motor vehicle industry. As you would probably be aware, every model of the vehicle produced these days has new and specialised electrical equipment and naturally, this requires highly specialised technical expertise to install, repair and maintain.

So what are the characteristics of a good industrial electrician that might make choosing one easier for you?

Let’s take a look at some of the things you should pay attention to:

  • Good industrial electricians have the experience and knowledge and, most importantly, the training required to work with highly specialised pieces of electrical equipment. It is of particular importance to check that their training is of sufficient depth to be able to work with the equipment required efficiently.
  • They should always possess the capacity to communicate well and be a good team player so that they can work as a part of a harmonious work environment.
  • Working as a part of an overall team is one thing, but specialised team members such as industrial electricians should also be able to communicate effectively with customers where necessary.

Naturally, every work environment has particular skill requirements and supervisors need to be careful to ensure that the industrial electrician they choose ticks every box, not just those listed above.

If you are still not sure about which industrial electricians you should choose.

What do you know about electrical transformers?

Posted on under General News

You may think that the way of delivering electricity to homes and businesses is pretty standard all over the world, but its voltage and frequency varies between countries or every region within a single country.

Essentially, electrical transformers are used to change the voltage of electricity so that it is suitable for different appliances and locations.

Where are transformers used?

Electrical transformers are commonly installed at the top of power poles or in electrical appliances. Sometimes they can be as small as a fingernail and used in items like radios, or they can be large and heavy devices that are used in power grids. Power grids have very high voltage so that the electricity can be transported long distances, but it must be reduced to become suitable for our homes. The voltage is lowered down through the transformer and then put into local wires at a substation where it may be stepped down again and again so we can use it.  

For example, the power from the grid may have a voltage as high as 765,000 volts, which can be lowered down to 7,200 volts through a substation. Then a local power pole transformer may drop the voltage further down to 220-240 volts before it is sent to your home. Larger appliances like water heaters may use this 220-240 volt electricity, but others like TVs and microwaves may need it even lower at 110-120 volts.

How do the electrical transformers work?

Transformers usually have two coils of wire in them, and some have more coils than the other.

When electricity in one of the windings transfers to a coil with fewer windings, the power steps down. And if the electricity in the coil with fewer turns in the wire is transferred to a coil with more turns, the voltage goes up. One coil is connected to an input circuit and the other is attached to the output circuit.

At the end of this article, we would like to mention also another type of transformers known as an autotransformer which is equipped with only one coil. Both circuits are connected to it at different points so that one circuit has more of the coil and more turns in the wire than the other. These transformers are often preferred because they are lighter, smaller and have better overload tolerance and voltage stability.

How to buy and use energy efficient appliances

Posted on under Tips

Using energy efficient appliances has become very popular in Australia over the last few years, but it can be hard to know what to look for.

In today’s article by Caslec commercial electricians, we would like to list some simple steps that can help in choosing the right product.

Energy star rating

The item’s energy star rating can help in making a quick judgement about its energy efficiency. The more star, the more energy efficient the appliance is.

Guides and product manuals

Many appliances have energy saving functions built in. It’s important to read the manual to learn how these can be used as it can save you a lot of money.

Recycling

Electrical appliances can be hazardous to dispose of, so it’s worth to find a retailer that can collect old items when they deliver the new product.

If your primary motivation for investing in energy efficient products is to save money, then remember the appliances that are not in use should be unplugged rather than left on standby. New televisions should also be set for the ‘home use’ mode which lowers the brightness on the screen and saves power.

Type of cabling you might need for your business

Posted on under Installations

For those who aren’t interested in the subject, cables are cables, but there is a distinct difference between electrical cabling which runs electrical current and communication cables that include all types of Data Cabling. Other common names for Data Cabling are Network Cabling and Data Network Cabling.

Commercial Data Cabling which is basically the same as Commercial Network Cabling refers to industries in which Communication Cabling is commonly used.

Data Cables are usually made of copper or optical fibre. Each of them has the capability to serve both data and communications, but each has varying strengths and purposes, for example, Telephone Cabling.

When Data Cabling is arranged in a certain fashion it is known as Structured Data Cabling or just Structure Cabling.

Structured Cabling design and installation is managed by a set of standards that specify the wiring of data centres, shops, offices, factories, schools, residential buildings etc for data or voice communications using various types and categories of data cabling with modular connectors. These standards describe how to display data cables in different typologies in order to meet the needs of the customer, typically using a central patch panel from which each modular connection can be used as required. Each outlet is then fixed into a network switch for data network use or into an IP or Private Box Exchange telephone system panel.

Wireless networks extend data and communications cabling beyond the physical range of data cables.

Our experts from Caslec in Sydney are qualified to service all kinds of Data Cabling and Electrical Cabling in accordance with all Electrical, Data and Telecommunications standards, which not all Electricians or Electrical Contractors are qualified to do so.

We are looking forward to discussing the specifics of your business electrical system

What’s involved in Energy Audit Report?

Posted on under Installations, Services, Tips

A comprehensive Energy Audit Report obtained by Caslec Industrial Electricians is an in-depth study into power consumption within your company premises.

Scope of Work:

·        Applying a data logger to the main switchboard for approximately 7 days, monitoring power, lighting and air conditioning system which measures and records the amps, voltages and harmonics being drawn from each circuit.

·        Entering every room throughout the premises to count all electrical equipment.

·        Identifying sub-boards and whether they require further data logging to measure accuracy.

·        Producing a graphical interpretation of the monitored results.

·        Formal presentation of the results and assistance in the implementation if required.

Energy Audit covers power, lighting, air conditioning and all other circuits that are used in your company buildings. Monitoring the power consumption over a week or longer will identify peak usage periods, highlight wastage, such as consumption in the evenings and weekends as well as inefficiency through load balance.

Have a look at some of our most common findings, our easy solutions and some more complexed ones.

Are you sure that your timers and sensors are working correctly? Did you know that due to power outages or human intervention they might not be working at all??

It’s time to check it.

On many occasions we have found hot water urns left on boil 24 hours a day, 7 days a week…wasting a huge amount of energy. Newer models are already programmed to turn off during out of hours or retrograde a timer onto older units.

Implementing energy saving company policies is an easy solution that saves a lot of money. Also, timers and sensors on lighting to ensure only security lighting system is left on when the building is not in use or upgrading older equipment to newer, more energy efficient products.

Electricity for your business. What’s the cost?

Posted on under Uncategorized

We all know that with consistent growth of inflation it’s becoming predictable that the electricity prices will eventually go up too.

If we look at the trend for the last decade in New South Wales, the increments aren’t slight either.

Price rises in electricity are inevitably met with dissatisfaction, especially in the domestic market where home budgets are smaller and the impact is applied more directly.

However, for commercial and industrial businesses it generally has a ‘knock-on effect’, usually by increasing prices for trade partners or consumers which in turn cycles back to increase inflation again. Otherwise, it becomes a loss in revenue for the company which may result in loss of jobs.

In this case, the argument for investment in energy efficiency is clearly stronger than ever:

·        We live in times of constant climate changes and environmental sensitivity.

·        There are the financial and potential productivity gains made from running a more efficient electrical system, which will invariably differ from company to company.

·        With the big potential ROI of between 3 months to 12 months, such an investment has the ability to pay dividends fast.

·        Investing in power optimisation will directly strengthen your local and national economy.

LED Installation Issues

Posted on under Installations

 

I have noted an article described as an advertorial in the 2016 July – August NECA NEWS (page 13)  regarding LED Power Supplies which I believe is a very important article for commercial electricians in Sydney to understand and take important care in choosing LED lighting fixtures & associated controls.

In particular, it is very important for the LED fixtures & controls to have been approved by the Australian Standards to ensure that imported products are suitable for installation within Australia. Otherwise, various products suitable for other countries may cause early expensive failures of the light fixtures and the controls connected to the LED circuits.

Apart from providing electrical installations, Caslec also provides electrical maintenance services and recently a Caslec service technician was required to attend a large new LED lighting installation installed by another contractor who was having technical issues. Commercial electricians from Caslec in Sydney observed that the LED lighting installation & the general installation equipment and distribution switchboards were of a high standard, however, there were issues with circuit breakers tripping and several failed contactors at the lighting distribution switchboard.

Various tests were performed & it was concluded that the electronic drivers were permitting considerable inrush currents as can be seen within this particular graphic image, over a page. One 60 Watt LED light fixture was producing an inrush current of 39 Amps. This may only be for a minimal period however when there are a number of light fixtures connected to the circuit, as in this case, the inrush current is considerable, particularly at the maximum level of the switching cycle. One of the commercial electricians from Caslec created a graph that clearly displays the level of start current that is drawn by a single light fixture during start up. As an example, 10 light fixtures on one circuit will certainly strain any normal lighting circuit including the controls, even during a minimal section of a single cycle.

The light fixture drivers external to the light fixtures were not approved for Australian installations resulting in costly replacements, even though the LED fixture itself is certainly of high quality. LED’s are the new lighting technology that is being embraced by almost everyone in Australia but they are not simple incandescent globes or fluorescent lamps. LED’s emit light but are grouped with other electronic components & devices, including additional controls that are associated with these devices.

The controls have to relate to the LED’s and the actual incoming power supplies within Australia & conform to Australian Standards.
