PD Free Resonant Withstand Voltage Test Set , Transformer Induced Voltage Withstand And Partial Discharge Test
I. Products description :
FKWJF series test system is mainly used for field induced voltage withstand and partial discharging test of power transformers 110KV class and above. This system adopts PD free push-pull variable-frequency power source technique which ensure fine sine wave and proper test frequency output during testing under iron core unsaturated condition of power transformer .The system can also be designed compatible to test long distance XLPE cable or HV GIS.The above pictures is for transformer induced voltage withstand &partial discharge test system made by Fanke to testing for 220KV power transformer in the field.
Induced voltage withstand test(IVWT), also called induced overvoltage withstand test ,ACSD,ACLD, DVDF, is one of most important dielectric test of power transformers.As per IEC60076-3-2013, IVWT is necessary routine test and acceptance test ater installation for abobe 110KV Power transformer .
