TYDZ-100KVA/0.4KV/0~6.3KV Voltage Transformer

Mode: TYDZ-100KVA/0.4KV/0~6.3KV
Single phase                                             Rated Input Voltage: 0.38kV
Frequency: 50Hz                                      Rated Input Current: 263.2A
Cooling methods: ONAN                        Rated Output Voltage: 0~0.63kV
Rated Capacity: 100kVA                         Rated Output Current: 0~158.7A
Regulating methods: Motor drive          Aberration Ration of Waveform: ≤3%
Starting Voltage ≤1.5%
Short-circuit Impedance:≤7.5%(in range of 50%~100%,impedance is being linearity)
Mode of Regulation: electrical drive
Operation Time: working for 60 min under 100% rated voltage and current
Short-circuit capability: When test transformer discharge to the test object via damping resistance under transient state, short-circuit current reach 2 times of rated value. The discharge last 8 circle will no damage regulator’s winding or mechanical distortion.
Overload capability: 1.2UH, 30min; 1.4UH 15min; 1.6UH, 5min;
Partial Discharge Level: <5pC Working time: at least continuous working for1 hour
Product structure: ① There are upper and lower position limited, oil drain valve, oil level indicator
                                 ②Regulating unit and raise voltage raising units are set together.
