What is partial discharge? Methods for measuring PD. How PD impacts high-voltage cables. Partial discharge (PD) is evidence of a degrading insulation system, which could trigger costly repairs and ...

Dogged by decades of under-investment, grid operators are turning to smarter grid-enhancing technologies to predict potential failures before they happen, improve system reliability, and save on costs ...

Electrical insulation is the cornerstone of high voltage system reliability, serving to impede undesirable current flow and thereby prevent catastrophic failures. Integral to the performance of ...

For more than 50 years, companies have performed partial discharge (PD) testing on electrical assets as part of ongoing predictive maintenance programs. Data obtained through PD testing and monitoring ...

How EMI testing can provide a condition assessment of an entire system. A look at EMI receivers. How EMI helps with partial-discharge testing. Electromagnetic-interference (EMI) diagnostics is defined ...

Over the years, Hendrix has maintained that porcelain insulators (and porcelain spacers) should not be used with covered conductor. This is due to the dielectric incompatibility between the two ...

Motors and generators are critical components of electrical systems. They are used to automate numerous industrial processes, circulate liquids for cooling and lubrication purposes, and generate ...

This article discusses the evaluation of a small 0.75 hp, 4-pole, 460 V, AC induction motor. The original insulation system of the motor was a typical Class 155C (Class F) material with a Class F lead ...
