Variable resonant frequency test system HDXZ-270kVA/270kV

HDXZ-270kVA/270kV Variable Frequency AC Resonant Test System is applied for AC dielectric test for electric equipment. 1. 10kV/300mm2 cable 3km AC withstand test,capacitance≤1.1265uF,test frequency:30-300Hz, test voltage 22kV, test time 5min; 2. 35kV/300mm2 cable 1km AC withstand test,capacitance≤0.1945uF,test frequency:30-300Hz, test voltage 52kV, test time 60min; 3. 110kV/630mm2 cable 0.2km AC withstand test,capacitance≤0.0368uF,test frequency:30-300Hz, test voltage 128kV, test time 60min; 4. 110kV/63000kVA Transformer AC withstand test,capacitance≤0.02uF,test frequency:30-300Hz, test voltage below 160kV, test time 1min; 5. GIS 110kV, Switching busbar and other substation equipment, AC withstand test,test frequency:30-300Hz, test voltage below 265kV, test time 5min Features ● With the function of over-voltage, over-current, zero-start, system detune (flashover) protection. Over-voltage, over-current protection value can be set accordingly to user’ need. Flashover protection action when the test object flash over and tester records the flashover voltage value for testing analyze. ● Small volume, light weight, very suitable for the operation people on the spot. ● There are three kinds of working modes, which is convenient for user choosing according to on-site condition. Working modes : Automatic mode, Manual mode, Automatic tuning manual boost mode. ● Data can be stored and printed in different places, and the series numbers are figures which is convenient for identification and searching.
