TYDZ-400KVA/0.4KV/0~3.3KV Contact Type Voltage Regulator

Mode: TYDZ-400KVA/0.4KV/0~3.3KV
Single phase                                  Rated Input Current: 1000A
Frequency: 50Hz                          Rated Output Voltage:0~3.3kV
Rated Capacity: 400kVA              Rated Output Current: 0~121.2A
Rated Input Voltage: 0.4kV         Aberration Ration of Waveform: ≤3%
Short-circuit strength: When the test transformer discharging to test object via protection resistance, the short-circuit current reach 5 times output, discharge continue 5 cycles no damage to regulator winding or cause any mechanical distortion.
PD Level: <5pC at 100% rated voltage (Together with system considerations)
Temperature raise: Regulator output capacitance reach 440kVA in 10 min, regulator oil surface temperature raise 55K, winding temperature raise 65K.
Note: include - magnetism oil surface indicator, servo motor driving device, position indicator with terminal contacts and protection contacts.
Operation Time: working for 60 min under rated voltage and current.
