Mode: HGTS 1000KV/600KVA
Casing, Stationary type Frequency: 50Hz
Single phase Rated Capacity: 600kVA
Rated Voltage: excitation winding: 2x6kV; HV winding: 1000kV
Rated Current: excitation current: 2x50A HV Current: 0.6A
Low voltage winding can serial connection or parallel connection:
When serial connection, HV output is 500kV 0.6A
When parallel connection, HV output is 1000kV 0.6A
(HV terminal of the transformer will be earthed through a current transformer 5/5 so as to check the current value of HV side and ensure safety of the operators and equipment)
