The HVA200 cable test system has been added to the HVA series of test sets from b2 electronic. It is suitable for laboratory use or can be fitted as a mobile test laboratory into a van.
The compact device offers VLF (very low frequency) 0.1 Hz standard testing as well as DC output voltage up to 200 kV peak (138 kV rms), allowing the user to perform voltage withstand tests on assets with network voltages as high as 132 kV.
The symmetrical, load-independent true sine wave output voltage wave shape makes repeatable Tan Delta (TD) measurements possible, allowing the global health of the cable insulation to be assessed, while the offline partial discharge (PD) mapping module allows minor insulation defects or jointing errors to be detected and located before they lead to premature cable failure.
The device has no limited operating time and has been tested according to IEEE400. It weighs about 850 kg and has transportation and mounted solutions available for asset owners and contractors interested in bringing this level of testing capability in-house.
As with the rest of the series, the product may optionally include a module for performing highly sensitive cable diagnostics alongside the withstand test.
