TE-Metrology
HIGHVOLT Prüftechnik Dresden GmbH
The TE measurement complements the high voltage test and is part of the routine and type testing of numerous electrical devices. It is one of the most important non-destructive methods for detecting faults in electrical installations. The breakdown of an insulating material usually occurs at an internal weak point, which usually already shows a partial discharge activity in advance. For this reason, measuring partial discharges can help prevent costly damage. The TE measurement is thus used for quality testing and diagnosis in the factory as well as during on-site testing of cables, GIS, power transformers and transducers or rotating machinery and their components

HV AC Voltage Test Systems
Fivestar HV Testing Equipment Co., Ltd.
FSHV offers three different types of AC voltage test systems, the conventional type is AC test transformer design, mainly for testing objects of medium & low capacitance products, particularly for tests requiring stable voltage even if the load changes under voltage (corona, wet & pollution tests) or when the load is inductive (like inductive voltage transformers). Another is AC resonant test systems, according to series resonance circuit XL=XC (2πfL=1/2πfC), by setting F frequency of power supply or L inductance of reactor, generate a pure sinusoidal waveform of the test voltage, and the required input power is only 1/Q. Variable frequency type operates in a frequency range from 20Hz to 300Hz, ideal for field commissioning test of power cables and GIS/GIL. Variable inductance type outputs continuous AC voltage of power frequency (50/60Hz), mainly for factory testing of high and ultra-high voltage cables, power transformers, GIS, etc.
