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

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 ...

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

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 ...

Megger’s family of eight insulation testers offers test voltages from 10 V to 1000 V for installation, maintenance, service, and repair work in the electrical, power, and telecommunications industries ...

Testing insulation is an important way to qualify a new installation. Testing also protects and prolongs the life of electrical systems and motors. Over the years, electrical systems are exposed to ...

As DC high-potential testing starts to show its age, test methods recommended by IEEE are ready to fill the void For many years, high-voltage DC testing has been the traditionally accepted method to ...

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 ...

Most design engineers take wire for granted and don’t give much thought to its basic wire-covering insulation. And why should they? In most cases, the insulation fulfills its role of preventing bare ...

A new hyper-scale data center was built in rural New Jersey that’s served by more than 100 25kV cables. Six months into operation, a cable termination failed catastrophically, and the forensic ...
