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, ...

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 ...

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 ...

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 ...

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 ...

Based on standard test methods, wet insulation testing of photovoltaic modules consists of performing resistance measurement on the insulation of a panel immersed in a liquid solution bath. In this ...

DUBLIN--(BUSINESS WIRE)--The "Electrical Wire and Cable Insulation Materials Market - A Global and Regional Analysis: Focus on Application, Material, and Region - Analysis and Forecast, 2024-2034" ...

According to a bulletin recently released by NEMA, a report from the University of Toronto in 1985 illustrates the potential heating effects of Type NM-B Cable when encased in spray foam insulation.

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 ...
