The potential dangers when performing electrical testing are some of the first issues to be addressed when learning the relevant techniques and practises. Wether you’re a professional electrician or a keen amateur, safety is paramount and as such remains one of the most commonly discussed topics in the industry. Despite this, many people still persist in potentially harmful approaches to testing, often due to carelessness or lack of knowledge.

Partial discharge is an electrical discharge that does not bridge the space between two conducting electrodes, typically as a result of a localised breakdown in cable insulation in high-voltage systems. Due to the discharge not spanning the entirety of the insulation, thus not being electrode to electrode, the discharge is referred to as ‘partial’ in nature.

Partial discharge can be classified according to three primary types: internal partial discharge, occurring inside insulation; surface partial discharge, tracking across insulation; and corona partial discharge, from a sharp electrode into gas. Each kind of partial discharge is likely to manifest itself differently, however the effects are always harmful if left unchecked, degrading insulation’s protection over time. In most cases, insulation will eventually become unable to withstand the high voltage load, resulting in failure and the possibility of dangerous arc flashes. It has been observed that up to 80%

In March 2022 the Institution of Gas Engineers and Managers (IGEM) published a 17 page supplement to their G 11 “Gas Industry Unsafe Situations Procedure” document. This supplement, titled “Responding to domestic CO alarm activations/reports of fumes after attendance by the emergency service provider or the Liquefied Petroleum Gas supplier”, is intended to offer additional guidance to engineers who experience reports of a CO alarm activation or fumes in present within a domestic premise.

The guidance provides a safe procedure for addressing these situations, including when to escalate the incident to a specially qualified engineer, such as someone holding a CMDDA1 certificate. The procedure assumes the engineer is using a calibrated EN50379 approved Flue Gas Analyser, such as a Kane analyser, to establish if a genuine danger

In November 2020, the UK made the commitment to phase out the sale of all diesel and petrol cars and vans by 2030, with the aim of making us the first G7 country to decarbonise road transport. Central to this commitment is the promotion of zero emission vehicles, with electric vehicles (EV) pinned as the future of road transport.

What Is Power Quality & Why Is It Important?

With recent increases in energy prices and the continuing shift towards environmental sustainability, there has never been a better time for businesses to consider their energy efficiency. One of the more significant components of energy efficiency is power quality, with poor power quality often resulting in increased energy and repair costs. Below, we’ve included a comprehensive overview of power quality, how it can be measured and why and how you can make improvements.
