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

Complex grids depend on equipment such as transformers, protection relays, switchgear, and cables—each of which can develop ...

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 ...

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 ...

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 ...

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 ...

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 ...

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

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 ...

China recently made a significant breakthrough in high-voltage cable testing technology with the successful application of its first domestically developed special test bushing for connecting both ...

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 ...
