CVT Resonance Test Device

CVT Resonance Test Device

Brief introduction

BPXZ-CVT series resonant boost device mainly test for capacitive voltage transformer, test frequency must blow 50Hz. Because of the complicated geographical conditions in field, the traditional test device has been difficult to meet the test requirements and handling on site, BPXZ adjustable resonant boost device is the fist one used in site for calibration and test. It has been widely used for field test of 500kv and blow capacitive voltage transformer.

Product features

◆Output voltage and current waveform is good, distortion is less than 0.5%.

◆Need smaller capacitance, the required capacitance is 1/Q of the measured capacitance, and the value of Q can be 20-60..

◆Do not need over voltage protection. When the tested product breakdown, the system loses resonance and resonant high voltage disappears, reactor acts to limit the short circuit current and reduce damage of the test product.

◆Convenient to field handling, this device is dry type integrated serial resonant device, which is composed of excitation transformer and several resonant reactors, unit volume is small , weight is light and suitable for field using.

◆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.
