Energy Management

Optimising your electrical installation to minimise waste and inefficiency - energy management - is becoming one of the essential cost and customer saving metrics in modern business. Energy management is one of the best ways to reduce both your carbon footprint and running costs while ensuring you will have full access to the energy you need.

What is So Important About Energy Management Solutions?

Energy management services work in a number of ways to improve business ROI. The first (and arguably most important) advantage is to reduce costs. On average, energy represents 25% of all operating costs in an office building. Going green no longer represents a business expense - it actually reduces expenses.

Having an energy management system in place also reduces risk. The more energy you consume, the greater the risk that energy price increases or supply shortages can seriously affect your profitability. You also reduce your carbon footprint while actually improving the quality of your energy. When this happens, you also extend the life of your equipment.

At Rotric, we have the experience and the knowledge to undertake an energy audit of your workplace to see if you could benefit from any of the following solutions:

1

Power Factor Correction

Power factor correction aims to improve the power factor, and therefore, power quality. It achieves this using capacitors to offset inductive loads, for example motors.

The Power Factor is the ratio between the useful (true) power (kW) and total power (kVA) consumed by an item of equipment. A load with a power factor of 1.0 results in the most efficient loading of the supply. A load with a power factor of, say, 0.8, results in much higher losses in the supply system and a higher bill for the consumer. PFC is achieved by installing a PFC Unit to the electrical network.

Why Improve Power Factor?

The reduction of power consumption due to improved energy efficiency is a huge environmental benefit. Reduced power consumption = less green house gas emissions and fossil fuel depletion by power. This increases the efficiency of the power supply, delivering cost savings on electricity and a reduction in electricity bills as well as extra kVA from the existing supply.

You also get extended equipment life from reduced electrical burden on cables and electrical components.

How does a Power Factor Correction Unit Work?

A PFC unit is connected in Parallel with the load side of the Main Switch in an electrical installation. Once connected, it utilises capacitors to improve the power factor of the installation.

2

Voltage Optimisation

Voltage optimisation is an electrical energy saving technique that is used to regulate, clean and condition the incoming power supply in order to reduce the voltage supplied to the premises. Energy providers in Sydney, especially in the CBD, supply customers with higher than necessary amount of voltage to ensure all customers receive acceptable amounts of voltage taking into account customer loading and voltage drop. This means that incoming voltage levels are generally higher than required to operate equipment efficiently and often result in the following issues:

  • Increased energy costs

  • Malfunction

  • Overheating

Why improve voltage optimisation?

There is an environmental benefit to improving voltage optimisation – the reduction of power consumption due to improved energy efficiency. Improved power quality = less equipment maintenance and improved equipment life as well as a reduction in electricity bills.

How do voltage optimisation devices work?

Voltage optimisation devices are installed in between incoming supply and the end user equipment. These devices reduce voltage down to an optimal level, providing stable and reliable supply to plant and equipment.

3

Surge Protection

A surge protector is an electronic device used to protect electrical appliances and equipment against power surges and voltage spikes by blocking voltage over a safe threshold. It is good practice to utilize surge protection devices to protect high-end equipment. A surge protector will generally extend the life of these devices, and there is always the chance that a big power surge (lighting strike) will cause sever damage.

What causes a power surge?

Power surges originate from outside the electrical installation and can be caused by a number of items:

  • Lightning strikes

  • Power outages

  • Short circuits

  • Tripped circuit breakers

  • Damaged or faulty wiring

When we think of a power surge, often we think of a lighting strike. While these have potential to cause severe damage to equipment down the line, we must also be aware of the small power surges and voltage spikes that occur every day in the electrical system. These smaller voltage spikes can deteriorate electronic systems, reducing their life spans.

How does a surge protection device work?

A surge protector is installed in parallel with incoming supply between the supply authority meter and the main switch. An SPD then restricts the voltage supplied to an electric device by either blocking or shorting to ground the voltage above a safe threshold.
