Voltage calibration system CVT

for transformers

CVT Calibration System GDHG-103 system is to calibrate CVT, CT/PT in the substation or power plant. System includes 1. AC Resonant Test System, mainly used to inject high voltage to CVT,CT/PT. 2. GDHG-103 CT/PT Calibrator 3. HJ-275/132G3 Standard VT 4. FY95 VT load box 5. Other accessories GDHG-103 VT Calibrator is mainly used to calibrate voltage transformer. It should be used together with other equipment such as load box, standard VT etc. Features 320*240 LCD screen with back light. Using advanced circuit and DSP technology, to make resistance-capacitance and phase shift circuit more stable. Friendly interface, easy operation. Small size, easy to carry and convenient for on-site test. With RS232 port, convenient to connect with PC. Measure active component and reactive component of impedance or admittance for VT or CT secondary loop. Automatically indicate polarity. If the polarity is incorrect, the instrument will be cut off automatically and alarm.
