AC Resonant Test System
Yangzhou Power Electric Co., Ltd
Testing of certain apparatus requires much high voltage or current that a straight AC test system is not sufficient. Thus resonant test reactor with a variable core is needed. The main advantage of such test systems is lower input power and larger output power. The resonant test system is designed to compensate capacitance in the testing circuit precisely by tuning inductance of the test system. AC resonant test system is used for factory testing of middle, high and ultra-high voltage cables, capacitors, generators, motors, power transformers and gas-insulated switchgears.

AC Test Transformer
Shanghai Guantu Technology Co., Ltd.
How the AC test transformer prevents the overvoltage generated by the frequency conversion series resonance test device is a relatively simple problem, but the overvoltage caused by voltage fluctuation is difficult to appear when the overvoltage protection is set. Generally, the overvoltage of the frequency conversion series resonance test device will appear in the frequency sweep stage of the instrument, that is, in the process of finding the resonance point. Those who have used it know that in the process of finding the resonance point of the frequency conversion series resonance test device, the voltage and frequency have a parabola-like linear relationship. By default, the system finds the high voltage, that is, the apex of the parabola as the resonance point.

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.
