Resonant test system 1.it is widely used for Capacitive Voltage Transformer (under 500KV ) on-site test. 2.light in weight
Resonant test system,when we test the Capacitive Voltage Transformer (CVT) , the frequency must under 50HZ,at the same time, the geographical condition of the testing ground is very complicated, traditional equipment can not satisfy the transportation and testing requirement. XZB-H Adjustable Resonant Boost is the first adjustable resonant tester used for on-site test, and now it is widely used for Capacitive Voltage Transformer (under 500KV ) on-site test.
Products features
1. The output voltage waveform is good, distortion <0.5%.2. Need smaller capacitance, the required capacitance is 1/Q of the measured capacitance, and the value of Q could be 20-60.
3. Do not need over-current protection, the system would be mistuned if the measured equipment was broken through, the high voltage of the resonant boost device will lose, the reactor will limit the short circuit current immediately, would not add damage to the measured equipment.4. Convenient to field transport, this device is dry type integrated serial resonant device, which composed by excitation transformer and several resonant reactors, unit volume is small , light in weight, convenient to field transport.5.Perfect protection function, with zero position protection (forbid the system to start if the voltage output knob was not on zero position), over-voltage protection, over-current protection, flash-over protection, ensure the reliability of the system.
