Portable Variable Frequency Resonant Withstand Voltage Test Set , For 110KV Powe Substation Test Set
I. Application :
This test set model CHX-216KVA/216KV is designed for distribution
power substation on-site AC withstand voltage test with variable frequency resonant circuit
technology; the test set is made from variable frequency power
source,excitation transformer,modular and day type HV test
inductance(test reactor) and capacitive divider .Each piece is
samller and lighter than common heavy test transformer type on
testing large capacity tested boject .
Through modular test reactor is used in parallel or in series, it can be performed the following AC withstand voltage test:
No more than 27KV and 8A for 10KV cable.
No more than 54KV and 4A for 35KV cable.
No more than 108KV and 2A for medium voltage power substation, such as power transformer ,CT, PT, Breaker and so on.
No more than 200KV and 1A for 110KV power transformer ,GIS, CT and PT.
II. Main Components:
