Cable Testing & Diagnostics

 

Cable testing and diagnostics are various techniques used to help assess the overall insulation quality of medium voltage cable systems, such as withstand testing, tan delta testing, and partial discharge testing. Important information is provided that can be used to improve system reliability, reduce repair costs by conducting condition-based maintenance on most vulnerable cables, and prevent unnecessary and costly outages. 

The BAUR cable testing and diagnostics product portfolio covers all the important requirements to quickly, reliably, and cost-effectively test and diagnose the condition of medium voltage cables.

TrueSinus Digital Technology

Truesinus logo

 

BAUR's truesinus® is a voltage generation technology invented in 1990 and patented in 1995 for the very low frequency (VLF) high voltage cable test equipment. This unique system with its truly sinusoidal voltage shape (no distortion) allows non-destructive VLF testing and condition evaluation of high voltage cables in compliance with VDE, IEC, and IEEE 400 standards. The truesinus® technology provides a precise basis for significant and reproducible cable tests or condition evaluation with tan delta or partial discharge measurements. Furthermore, simultaneous measurements, such as monitored withstand tests (MWT) or Full MWT can be conducted.
