HGTS 1200KV/3000KVA Gas Insulated Test Transformer

Mode: HGTS 1200KV/3000KVA
Casing, Stationary type                                     Frequency: 50Hz
Single phase                                                        Rated Capacity: 3000kVA
Rated Voltage: LV Voltage: 2x10kV; HV voltage: 1200kV
Rated Current: LV Current: 2x150A ; HV Current: 2.5A
Low voltage winding can be serial or parallel connected:
When serial connected: HV output is 600kV 2.5A;
When parallel connected: HV output is 1200kV 2.5A.
(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)
Waveform deviation ≤3% Impedance voltage ≤18%

 
 

Over Current Ability: Continuous working for 300S under 120% rated current (3A), then thermal damage or distortion of the winding shall not be occurred.
Over Voltage Ability: Overvoltage at 110% UH (1260kV) for 60s, then it shall not happened any insulation damage for the testing transformer.
Insulation Level: 10kV/1min (low voltage input terminal to earth)
Partial discharge level: ≤3pC at 1000kV; ≤1pC at 800kV
Noise: ≤65dB                                                        Dielectric loss: <0.5%
Operating Time: at 1000kV 5000pF capacitance load, 5min on, 30min off; every day 20cycles.
Protection: Equip with 10kV surge arrestors.
