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 ...

The new dual-purpose instrument combines high-voltage insulation testing up to 20 GΩ with comprehensive electrical measurement capabilities for field electricians.

Researchers at Chalmers University of Technology (Sweden) have discovered that the insulation plastic used in high-voltage cables can withstand a 26% higher voltage if nanometer-sized carbon balls are ...

HVI has led the industry in manufacturing the most portable and easiest to use VLF test instruments since 1998. The E Series represents the apex of these efforts with the most advanced features and ...

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 use of high-voltage cables for the underground transmission of electric power is becoming more and more important from the point of view of economy, and also because as the network extends the ...

National Electrical Code (NEC) Table 310.104(C) is titled “Conductor Application and Insulation Rated 2,001V or Higher.” For MV solid dielectric cables, there are two basic types of insulation: ...

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, ...
