It uses an excitation transformer to motivate series resonant loop, to adjust the output frequency of the director, make the loop inductance L, and measured equipment C in series resonant, the voltage of the resonance is the same as tested equipment.
XZ CVT 108kVA 108kv 4 Reactors Variable Frequency AC Resonant Test System is widely used in Electric Power, Metallurgy, Oil, Chemical Industry, etc, applicable to connecting and preventing tests for capacitive equipment with high-capacity, high-voltage.
Its main function is to change 380V or 200V (the amplitude and frequency are fixed) frequency sine wave AC power into sine wave (amplitude and frequency are adjustable), and supply power for the whole system.
The function of the excitation transformer is to boost the output voltage of the power source to the proper measured voltage. High voltage reactor L is an important component of the resonant loop, it with measured equipment CX in serial resonant when the power frequency=1/(2π )
XZ 35kV Switchgear Busbar Hipot Testing Equipment, GIS Hipot Testing Equipment applies to AC voltage withstand tests of 10KV, 35KV, 110KV, 220KV, 500KV polythene cable, 60KV, 220KV, 500KV GIS, large transformers, generators, transformer induced voltage withstand test, and ground resistance measurement.

High stability and reliability. Voltage and frequency output is stable, design for electromagnetic compatibility is reasonable, perfect protecting protection, the system is still good after several tests high voltage to earth short circuit , meanwhile the system with strong over-load ability.
Powerful automatic tuning function. When the system automatic tuning, auto scanning from 30Hz to 300Hz, display the scanning curve, customers can clearly view the tuning process; after finished the scanning, system will find out the resonant point, makes frequency fine tuning within its range ±5Hz with resolution 0.01Hz, finally accurately lock the resonant frequency.
Multi test modes: automatic tuning + manually regulating voltage, automatic tuning + automatic regulating voltage, manually tuning + manually regulating voltage, we suggest the mode: automatic tuning + manually regulating voltage, which can fast find out the resonant point, it also can control the measurement process by manually regulating voltage, more safe.
Friendly man-machine communication interface, parameters setting, test controlling , test results displayed in one screen, clear and visible, with auto timing and operation indicating functions, full touching screen, can store and review the test data.
Perfect protecting functions, with zero position protection (forbid the system to start if the voltage output controlling knob was not at the zero position), over-voltage protection, over-current protection and flashover protection, ensure the safety of the system.
