PHG 70 portable / PHG 80 portable VLF test system

The BAUR PHG 70/80 portable VLF test systems are used for cable and cable sheath testing of medium-voltage cables of up to 50 kV and electrical equipment. The programmable high voltage generators offer 3 tried and tested voltage shapes:
VLF truesinus® and VLF square wave
BAUR VLF truesinus® digital technology enables the most reliable detection of damage and offers the comparability of measurement results by means of load-independent voltage generation with digital control. Unlike other voltage shapes, the voltage is exact, symmetrical and continuous. The cable length has no influence on the test level. Medium-voltage cables are tested with utmost care and in compliance
with the standards.
DC voltage
For DC voltage testing, e.g. for paper insulated mass-impregnated cables, the PHG 70/80 provides a stabilised DC voltage with positive and negative polarity of up to 80 kV. The PHG system satisfies the highest requirements with regard to safety, robustness, operational convenience and automation. Customised test sequences can be defined and saved via the self-explanatory menu control. High-voltage electrical
breakdowns are automatically recognised during the test. The system either switches off automatically or goes into burn mode after the breakdown according to how it is programmed.
