Complex grids depend on equipment such as transformers, protection relays, switchgear, and cables—each of which can develop faults not immediately visible during normal operation. As a result, ...

The street scene shows damage caused by an explosion in a manhole as a result of gases generated by a low-voltage arcing fault. North America, according to statistics published by the IEEE Insulated ...

Why is VLF Hipot testing becoming more important in modern power networks? VLF Hipot testing is widely used for assessing the ...

Most of the electrical power distribution infrastructure is static, and in many facilities, the mindset for electrical equipment and devices is “set it, and forget it.” However, much of the existing ...

An AC resonant test system is designed to generate high alternating voltage by forming a resonant circuit between the reactor and the test object. By operating at or near resonance, the system can ...

The measurement engineer can view the values from tan δ and partial-discharge testing directly in the cable test van. Clear representation helps to detect severe defects or locate partial discharges ...

Acceptance test reports can tell you the condition of your cables when they were installed, but they tell you nothing about the present condition. Startup alone can radically change the data ...

For over 60 years, polyethylene (PE) and ethylene-propylene rubber (EPR) underground cables have powered communities, ...

Insulation problems are to blame for around 30% or more of motor failures – meaning that electrical motor testing should be a larger part of every condition monitoring regime. Mike Teska, Product Line ...
