LONG-TERM PROJECT, QUALITY FIRST.
Add to Cart
This resonant tester is widely used for Capacitive Voltage Transformer (under 500KV) on-site test.
Features
1.The output voltage waveform is good, distortion <0.5%.
2.Need small capacitance, the required capacitance is 1/Q of the measured capacitance, and the value of Q could be 20-60.
3. No need over-current protection, the system would be detuned 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 transport in site, this device is dry type integrated serial resonant device which composed by excitation transformer and several resonant reactors, unit volume small and light
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, ensures the reliability of the system.
