Test Object: Sea Cables

 

Capacity Determination of the equipment:

4pcs Reactors will be designed, each reactor is 7000kVA/190KV. Capacity amount is 28000kVA.

Determination:

Configurations of HV reactor, divider, variable frequency power generator and exciting transformer:
♦  HV reactors: 190kV/36.8A/60min/4pieces in series applied on AC voltage withstand testing.

♦  Divider: 400kV/1000pF (designed as two pieces), each piece rated at 400kV/2000pF. Two pieces used on high voltage measuring and system no-load resonant.

♦  Variable Frequency Power Generator: 1500kW, input 380V three phase, output single phase 500V. Full set power supply used to provide resistive loss of whole test circuit.

♦  Exciting transformer: 1500kVA, input 500V, output 10KV, 20KV, used to increase the output voltage of variable frequency generator to applicable exciting voltage, and applied for reactor resonant.
