About TEGG Energised Maintenance Introduction History of TEGG Why Choose TEGG? Traditional electrical testing techniques often require a building s power to be shut down. This causes huge disruption to business activity and is a particular problem in uptime-critical environments such as data centres, financial institutions, manufacturing plants, public buildings, airports and hospitals. TEGG Service overcomes the downtime issue by performing an in-depth energised assessment of a building's electrical infrastructure whilst operating under normal conditions and loads. TEGG was founded in 1992 to offer comprehensive electrical preventative maintenance services to commercial and industrial facilities. Since then TEGG Service has helped protect clients in these industries from electrical system failures, electrical fires, and resultant business interruptions and property damage. Metropolitan joined the TEGG network in 2006 and has become one of the most successful franchises in the UK. TEGG Service goes beyond the inspection and testing regime required by BS7671, allowing early identification of issues that can very quickly lead to device failure and an unscheduled power interruption. As we carry out energised testing without the need for a shutdown, our clients don't lose production time. By testing under load in real time, the information we gather is much more useful when predicting the condition of components. In addition, you ll have access to our bespoke software, which makes it easy for you to prove compliance to electrical legislation and demonstrate that your business has a fixed price, planned maintenance program in place. On completion, your TEGG Service reports will be available to view, print and distribute on our dedicated portal, TEGG Pro View. We re so confident in the quality and sophistication of our testing services, our results are guaranteed. If a component included in a preferred multi-year agreement is reported to be in healthy condition and subsequently fails, we ll replace it free of charge.
The TEGG Service Common TEGG sectors Methodology The TEGG Service methodology involves a unique set of processes and utilises the most advanced technologies available. This enables our technicians to collect all the data required for accurate condition reporting in a safe testing environment. Before carrying out our energised assessment, gloves are tested with the Ultrasonic probe to ensure their integrity and Arcflash PPE is inspected. This ensures the safety of our technicians and building occupants by preventing the risk of arc flash, a potentially fatal electrical discharge or explosion that can occur in the absence of adequate safety precautions. Each asset is uniquely labelled which allows it to be easily traced on site and in our reports. Digital and thermal baseline images of each electrical device included in our survey are then recorded, followed by recording of ultrasonic sound files. Voltage, current and power quality analysis testing is the next step, which we perform on each piece of equipment and document accordingly. Detailed images and sound files are recorded of any thermal or ultrasonic anomalies found and any suspected power quality issues are investigated. At each stage of testing, data is uploaded to our bespoke TEGG software for analysis. Detailed reports including baseline, anomaly and variables are then generated and issued. Each component is clearly identified and its associated test data is made readily available. By utilising this information, we can build a database of the condition of each asset on site that can be stored, shared and accessed at any time. TEGG provides vital testing services for any business with mission-critical electrical systems operation and minimal downtime opportunities. We work across a wide range of sectors including: Commercial offices Data centres Banks and financial institutions Healthcare premises Large corporations Educational establishments Heavy industry
Case study #1 Goldman Sachs Data Centre Case study #2 Telstra Global TEGG provides essential monitoring and preventative maintenance at a data centre for this leading global financial institution. The results of a TEGG ultrasonic survey of transformers and cable termination chambers at the data centre enabled us to identify a potentially catastrophic issue for Goldman Sachs. By identifying a suspected faulty transformer, and analysing its sound files, we discovered an arcing issue on the incoming HV cabling within the transformer. If left undetected, the cable insulation would have failed, resulting in severe damage to the transformer and ancillary equipment in the switch room. Due to the severity of the issue and risk of failure, site staff were immediately notified and were able to transfer the load to the alternative supply and remove the transformer from service. A thorough visual inspection and investigation was carried out and a detailed report of our findings and analysis issued. Our investigation found that the HV cabling had been incorrectly installed resulting in discharge between phases. Visual inspection of the remaining transformers found several instances of the same fault. To remove the risk of similar faults the cables were replaced and installed correctly. Our annual inspections now include an assessment of all transformers to allow ongoing safe and reliable service. Telstra Global, one of the world s foremost telecommunications companies, relies on TEGG to test and maintain vital parts of its electrical infrastructure in several of their buildings. During a routine TEGG survey at a colocation data centre, we detected high temperatures on the gland terminations above the incoming cable chamber of a low voltage electrical panel. Despite visual and physical access restrictions, our assessment showed the issue had been present for some time. With no intervention, Telstra data halls would overheat, causing potentially costly business disruption. After informing the client of the severity of the issue, we set up a program of monitoring and investigation visits. This involved detailed thermal imaging and power quality analysis, which allowed us to trend the temperatures and loads over the following weeks. Our analysis uncovered major faults in the single core cable configuration. Power quality analysis confirmed that the cores were not sharing the loads evenly, compounding the heating effects. Following detection and diagnosis we installed new containment and cabling between the transformer and LV panel. A planned generator run allowed us to isolate the transformer and connect the new cabling. Early intervention prevented the failure of the cables and severe damage to the switch panel.
Testimonials We ve used TEGG on a quarterly basis in our main HV and LV infrastructure. We also use it on the UPS systems, distribution systems and even as far down as the data haul powered supply systems. TEGG is the only alternative for live testing. Whilst you can carry out thermal testing, and visual inspections, nothing can beat the TEGG ultrasonic sound testing. Kevin Sell, Telstra Global The non-intrusive part of the maintenance is a massive benefit for anyone who has trouble gaining shutdown ability. Making sure we get visibility of any problems that are out there without having to shut down is clearly a real benefit. While using TEGG there have been situations where we ve found problems, we ve found hotspots, we ve checked them with the ultrasonic testing. That has enabled us to make some key business decisions without going into crisis mode and then doing a planned operational shutdown and enabled us to fix the problem.
