Power Quality Issues – Part 5 – Reactive Power and Power Factor
Based on recent feedback from a specialist power quality improvement service business, the issue of high reactive power and poor power factor is becoming increasingly common in the UK today, an issue which apparently used to be considered much more widely by electrical engineers and facility managers.

How an 11-Day Energy Audit Uncovered Long-Term SavingsReport to the head teacher’s study!
It’s all very well to write about what portable energy loggers (PELs) can do and the sort of benefits they might provide but how do things work out in a real application? To answer that question, an 11-day energy monitoring exercise was carried out at a secondary school in Kent. Julian Grant of Chauvin Arnoux discusses the results.
WATT a Turnaround: Power Logging Slashed Energy Use by 50%
Even before energy prices started their recent almost exponential climb, businesses could cut their energy bills dramatically simply by analysing their energy usage and identifying opportunities for improvement. Following this approach, a major processor of fresh fruit cut its energy bills in half, as Julian Grant of Chauvin Arnoux explains.
How the right power and energy logger can help identify issues with maximum demand and harmonics.
Many domestic installations today are seeing changes in the nature of the electrical equipment being installed in them, or requested to be installed in them, and notably the addition of some fairly high current loads, including most recently heat pumps and EV charge points.
The Invisible Costs of Inefficiency in Industrial Systems
Monitoring energy consumption has become essential for organisations aiming to cut expenses and improve operational efficiency — particularly in the face of rising electricity prices.
Improving our own energy efficiency – Part 2
In the previous issue of Energy Manager Magazine, we described the beginning of a journey to improving the energy efficiency, and so reduce the consumption, of the Chauvin Arnoux UK offices. Following that initial logging session, and the subsequent changes that were made, more logging was performed using a PEL104 Power and Energy logger. This second part looks at the resulting data, and reveals the effects that the initial changes had on our consumption.
