Finding the Electrical "Needle in the Haystack" Every day, thousands of metres of electrical cables silently distribute power throughout buildings, factories, data centres, hospitals and critical facilities. Most inspections focus on the obvious locations: switchboards, distribution boards and control panels. But sometimes the defect that causes tomorrow's failure is hiding somewhere nobody is looking. During a recent thermographic survey, MET engineers identified a thermal a

In mission‑critical environments like data centres, switching the power off is simply not an option. Red Centric, one of the UK’s leading data centre and cloud service providers, needed a specialist electrical testing partner who could deliver accurate, reliable, and safe results without interrupting live operations. That’s exactly why they chose MET Group Technical Services. Zero‑Downtime Testing for High‑Availability Facilities Data centres operate 24/7, supporting thousand

The Importance of Electrical Maintenance in Historic Structures At London Tower Bridge, MET Group successfully carried out specialist energised testing on live electrical infrastructure, allowing essential inspection, diagnostic, and performance verification activities to be completed without disrupting the operation of one of the UK's most recognisable landmarks. Through detailed planning, advanced test methodologies, and highly skilled engineers, our team obtained critical

Critical power systems depend heavily on reliable electrical distribution components to ensure continuous operation. Among these components, busbars play a vital role in conducting large currents efficiently and safely. Proper maintenance of busbars is essential to prevent failures that could lead to costly downtime, equipment damage, or safety hazards. This article explores the key aspects of busbar maintenance in critical power systems and offers practical guidelines to kee

Engineers from MET Group recently visited Amcor's facility in Finland to gather the necessary electrical data for a comprehensive Arc Flash Study. This involved collecting crucial data from both LV and HV infrastructure. Kudos to the engineers for maintaining their smiles despite the chilly Nordic weather. This visit also underscores the extent of our European presence. Through our ongoing projects with Amcor and other key clients, MET Group now provides expert electrical eng

Switchgear plays a vital role in managing electrical power systems, controlling the flow of electricity, and protecting equipment from faults. Despite its importance, switchgear maintenance is often overlooked or delayed because it usually requires shutting down power, which disrupts operations. This delay can lead to serious safety risks, unexpected failures, and costly repairs. Understanding why regular switchgear maintenance is essential and how it can be done without inte

Maintaining electrical infrastructure in skyscrapers presents unique challenges. Recently, we completed essential busbar maintenance at 22 Bishopsgate in London, a landmark known for its impressive height and architectural significance. This post explores the importance of busbar upkeep in such a towering structure and offers insight into the technical and logistical aspects of the work. The Significance of 22 Bishopsgate Standing at 278 meters, 22 Bishopsgate is one of the t

MET Group engineer servicing an ACB Air Circuit Breakers (ACBs) are one of the most critical protection devices in a building’s electrical infrastructure — yet they’re often ignored until something goes wrong. At MET Group Technical Services, we specialise in planned ACB servicing and live testing to ensure your electrical system remains safe, compliant, and fully operational. Why ACB Servicing Matters An ACB protects your building from overloads, short circuits, and equipmen

What Is a Busbar System? A busbar system is a metallic strip or bar used for local high current power distribution. It connects incoming power to multiple outgoing circuits, acting as the backbone of your electrical system — especially in commercial buildings, data centres, and industrial facilities. Despite its importance, many facilities managers focus on switchgear, transformers, and breakers — forgetting that the busbar is just as vital. Why Busbars Get Overlooked • Hidde

We are thrilled to begin the French phase of the most extensive arc flash study rollout across Europe, which will span five years for global packaging leaders, Amcor. This project aims to deliver the highest level of electrical safety data for anyone working at an Amcor facility. Tony Marshall Managing Director Engineers from MET Group Power Systems visited sites in Montpont France to gather data fr

MET Group Technical have secured a national contract with one of the UK's largest retailers, facilitated through our client, CBRE. This engagement allows MET Group to strategically utilise our expertise across a portfolio of over 330 sites, providing thorough, data-driven energised testing and MET’s Sonic Trace service. Our position in the market makes MET Group the leading provider of energised inspections for electrical assets in the UK and Europe. Our Inspections program i

Throughout October, engineers from MET Group Technical and MET Group Sonic Trace visited sites in the UK and Europe to conduct testing on some of the world's most vital facilities for life and business. The inspections conducted across 36 facilities uncovered more than 278 issues that could have eventually resulted in critical failures, with 107 of these issues being pre-thermal anomalies. As leaders in the industry, we come across both new and existing busbar installations t
