The Importance Of Power Quality

The Importance Of Power Quality

Electricity is transported and delivered across the power grid to businesses worldwide. It is used to power a wide range of equipment and electronic devices, often without a second thought—until something goes wrong.

Developed countries take for granted their capacity to plug into a reliable and safe electrical supply at any time, but few consider the quality of the power they are using.

Have you ever wondered, "How good is the power quality of the electricity powering my electrical systems and sensitive equipment?"

Few business owners ask this question, yet it can be the key to saving money on energy bills, improving productivity, reducing maintenance costs, and extending the lifespan of machinery. The power quality being delivered to a building can and should be optimised to provide more reliable, consistent, and safe electric power.

Why is Power Quality Important?

Good power quality is essential for several reasons. First, high-quality electricity is more efficient, allowing equipment to run on optimal energy consumption. This saves money on electricity bills, and reduces overall power consumption and carbon emissions.

Using high-quality power reduces the risk of equipment failure, overheating, and the need for frequent maintenance, minimising wear and tear on machinery.

Breakdowns, overheating, and excessive maintenance all come at a cost, and smart businesses want to minimise these events. Improved power quality increases productivity for manufacturers and allows facilities to maximise their distribution capacities.

Investing in power quality is an investment in the quality of your business operations.

Poor electric power quality may manifest in various ways, including:

• Short or extended power interruptions

• Noisy electrical equipment

• Voltage fluctuations, dips, and swells

• Harmonic distortion

• High-speed transient voltages

• Damage resulting from lightning strikes

Comprehensive power quality analysis and monitoring can identify how a building or facility can optimise its power supply. This is often prompted by obvious issues such as equipment malfunctions or power interruptions. A thorough power quality audit will uncover hidden power quality problems, and the resulting corrective actions can significantly improve energy consumption and costs.

The Impact of Poor Power Quality

Poor power quality can have serious consequences for businesses and their electrical systems. Voltage sags, harmonic distortion from non-linear loads, and low power factor can all contribute to equipment damage, premature failure, and unexpected downtime.

Voltage variations outside acceptable power quality standards can cause sensitive electronic devices and equipment to malfunction, leading to data loss, process interruptions, and financial losses. Surviving voltage dips, surges, and swells with surge protectors is important, but it does not address the root causes of poor power quality.

Harmonic currents and voltages, often generated by nonlinear loads like arc furnaces, can induce overheating in motors, transformers, and electrical infrastructure. This harmonic distortion reduces the efficiency of the electrical system, increasing energy costs. Installing harmonic filters can help mitigate the impact of harmonics.

The Key Role of Electrical Engineering

Electrical engineering expertise is essential for analysing power quality issues and implementing the right solutions. That's what we do best here at Quality Energy. We design, manufacture, install, and service power quality solutions.

Investments in improving the quality of power through power factor correction, and better monitoring systems can deliver significant long-term cost savings. By protecting sensitive electronics and optimising energy efficiency, businesses can reduce operating expenses and maintenance requirements.

What is Power Quality Monitoring

Power quality monitoring involves installing meters to continuously provide accurate measurements of electric power quality parameters. This allows energy experts like Quality Energy to improve and optimise the power quality with specialised equipment as needed.

Any business seeking to improve the reliability and efficiency of its electrical energy supply should conduct periodic power quality audits.

Quality Energy has conducted power quality analyses for a wide range of facilities, including industrial sites, commercial buildings, data centers, mining operations, and oil and gas installations worldwide.

Maintaining Optimal Power Quality

Ensuring good voltage quality and power factor is essential for the reliable operation of electrical devices and control systems. Power quality monitoring systems can track parameters like total harmonic distortion, voltage levels, and reactive power to identify problems.

Addressing low power factor through power factor correction equipment can improve the efficiency of the electrical system, reducing active power losses and energy consumption. This in turn lowers electricity bills and operating costs.

As businesses increasingly adopt renewable energy, maintaining high power quality becomes even more important. Fluctuations in voltage and frequency from intermittent solar and wind generation can disrupt sensitive electronic equipment and control systems if not properly managed.
