AC Withstand Resonance Test System
Cable Resonance Test System Brief Introduction
ZCVF-B AC Resonant Test System (for Cables) are composed of frequency/voltage adjustment power,exciting transformers, reactors, capacitive divider.The power frequency can be adjustable,which make the reactor and tested capacitor resonance.
Product Features
1. The frequency conversion power supply is placed in a vertical and horizontal direction, and is especially suitable for the field operation and observation;
2. The inner and outer parts are provided with a special damping rubber support foot and a protective aluminum box, which can effectively slow down the impact of the vibration and the hoisting during the transportation. The long-term stability and reliability of the frequency conversion power supply is guaranteed;
3. Parameters display: touch or external mouse large screen LCD screen display system.;
4. Can display the resonant voltage (i.e. before the test set of target voltage), test frequency, frequency measurement, low voltage, low voltage current, pressure time, overvoltage protection, current protection, flashover protection, phase voltage and phase timing, switch the operation mode, capacitance, inductors, frequency rate swaps are calculated, parameter query, display frequency curve, voltage curve can be used to visually judge when test resonant frequency accuracy and stability.
