TYDZ‐250kVA/0.38kV/0~3.15kV Contact Type Voltage Regulator

Mode: TYDZ‐250kVA/0.38kV/0~3.15kV
Single phase                                     Rated Input Current: 657.9A
Frequency: 50Hz                              Rated Output Voltage: 0~3.15kV
Rated Capacity: 250kVA                Rated Output Current: 0~79.4A
Rated Input Voltage: 0.38kV          Aberration Ration of Waveform:≤3%
Short‐circuit strength: When test object breakdown, the short‐circuit current reach 5 times output, discharge continue 5 cycles no damage to regulator winding or cause any mechanical distortion.
Temperature raise: 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 100% rated voltage and current.
