  • Brief Introduction for BPXZ Series Resonant System

    Series resonant system exerts series resonance principle, uses 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, voltage of the resonance is the same as tested equipment. Frequency Resonant Testing Equipment are widely used in Electric Power, Metallurgy, Oil, Chemical Indus...

  • BPXZ-HT Cable Resonance Test System

    BPXZ-HT makes the reactor and tested capacitor in resonant by adjusting the frequency of the power source, to get high voltage and heavy current from measured equipment. Now it is a new method and trend for high voltage test and widely used. BPXZ-HT uses special SPWM digital wave-generate chip, resolution is 16 bits, the frequency adjustment fineness could be 0.1Hz if the frequency was 20~300Hz...

  • AC Resonant Test System (for Substation Equipment)

    Transformer, GIS, SF6 switch, CT/PT, insulator, bus bar, cable, bushing, and others capacitive devices are the common primary electric equipment. Composed by power control cabinet, excitation transformer, reactor, voltage divider, connects silicon rectifier stack and micro ammeter with the voltage divider, then can finish the DC voltage withstand test.

  • GPXZ-L Resonance Test System for Generator

    As the development of the electric system, the capacity of the equipment more and more larger, for example, the capacity of single machine of the thermoelectric generator group is more than 1000MW, the capacity of single machine of the hydroelectric generator group is more than 800MW, if use traditional equipment (frequency test transformer) , need large capacity, test transformer, voltage regulator are very ...

  • BPXZ-L Generator Resonance Test System

    This device is special designed for AC voltage withstand test for 11kV/30MW hydroelectric generator. It is composed by frequency power source, excitation transformer, reactor, capacitance divider. The advantages of serial resonant system:  1.Need smaller power capacity. The power of the serial resonant system generate high voltage and high current by resonant reactor and me...

  • XZB-H AC Resonance Test System for CVT

    When we test the Capacitive Voltage Transformer (CVT), the frequency must less than 50HZ, at the same time; the geographical condition of the testing ground is very complicated, traditional equipment can not satisfy the transportation and testing requirement. XZB-H Adjustable Resonant Boost is the first adjustable resonant tester used for on-site test, and now it is widely used for Capacitive Voltage Transfor...

  • BPXZ-W PD Free Resonance Test System

    BPXZ-W PD Free resonant test system is mainly used for testing power frequency withstand voltage of the insulation level of all kinds of insulation materials, insulation structure and electrical products, also as PD Free source for power frequency test of transformer, mutual inductor, and lightning arrester. Widely used in the electrical manufacturing sector, the power sector, scientific research institutes a...
