Power Quality keeps your Electrical Systems
100% Healthy,   and reduces your Electricity Bills.    

For a long time, the main concern for consumers of electricity was continuity of supply, but this is changing. Advanced technologies such as renewable energy sources, microgrids, electric vehicle chargers and inverters are creating an increase in non-linear loads, which can create challenges for power stability. While demand is on the up, power quality is wavering, resulting in poor performance of electrical systems, increased utility bills, additional unplanned maintenance and issues with continuity of supply. Other concerns include non-compliance to grid codes and reduced lifetime of equipment.

What does a Power Quality Health Check involve?

Here at Save Electricity Ltd, our aim is to help customers concentrate on the things that matter to them. Power Quality issues are often an unwanted surprise and can cause a huge amount of costly disruption.

The parameters monitored during the power quality analysis include, but are not limited to, the following: –

  • Voltage Dips and Swells.
  • Harmonics up to the 100 Group.
  • Voltage Transients.
  • Voltage unbalance.
  • Voltage Flicker.

The main deliverable of the Power Quality Health check is a comprehensive report detailing the findings of the power quality analysis and how this is influenced by the load and any mitigation measures already implemented on site.

Defining power quality

Power quality can be evaluated through a group of performance indicators and through standard defined limits that allow electrical equipment to operate as designed, without significant loss of performance or life expectancy. This definition implies the constant and stable supply of electricity throughout the electrical network.

When good power quality is in place, it creates a reliable power supply that is always available, has a pure noise-free sinusoidal wave shape and is always within voltage and frequency tolerances.

Common power quality issues

The most common power quality issues can be divided into long-term and short-term disturbances.

Long-term disturbances such as harmonics, unbalances, under/over voltages, low power factor and flicker, cause equipment failures, malfunctions, overheating and damage of equipment. Short-term disturbances, such as voltage variation and transients, are those with either visible and/or immediate impact such as unscheduled downtime, sudden equipment malfunction or damage and reduced efficiency of electrical equipment.

DNO Witness Test

You can see on this photo the amount of equipment we have to bring to site, when we are asked to do a G99 / G100 (ELP) Export Limitation Panel dno witness test, this site was in the centre of London, and is for a company that needed to use 94 Kwp but the DNO would only allow 60 Kwp, this equipment which we also supplied allowed this connection to take place.

So don’t let the lack of connectivity stop your clients from getting the connection they require, we will supply a bespoke panel at a competitive rate which will keep your client happy. And they will think you are you best thing since sliced bread.

And we will test anywhere in the UK and Ireland.
