Product Description:
HZBP-CVT series resonant boost device, test frequency must below 50Hz when mainly test for capacitive voltage transformer. Because of the complicated geographical conditions in field work, the traditional test device is difficult to meet the test requirements and move on site, HZBP 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 below capacitive voltage transformer.

Product Features:
1. Output voltage and current waveform is good, distortion is less than 0.5%.
2. Need smaller capacitance, the required capacitance is 1/Q of the measured capacitance, and the value of Q can be 20~60.
3. Do not need over-voltage protection. When the tested product breakdown, the system detuning and resonant high voltage disappears, reactor acts to limit the short circuit current and don't aggravate damage of the tested product.
4. Convenient to field moving, this device is dry type integrated serial resonant device, which is composed by excitation transformer and several resonant reactors, unit volume is small , weight is light and suitable for field using.
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, arc-over protection, ensure the reliability of the system.
