HGTS 300kV/150kVA Gas Insulated Test Transformer

Mode: HGTS 300kV/150kVA
Casing, Stationary type                                                                    Frequency: 50Hz
Single phase                                                                                      Rated Capacity: 150kVA
Rated Voltage:LV Voltage: 2x0.6kV; HV winding: 300kV          Rated Current: LV current : 2x125A HV Current: 0.5A

Low voltage winding can be serial or parallel connected
When serial connected, HV output is 150kV/0.5A
When parallel connected, HC output is 300kV/0.5A
(Test transformer HV terminal earth terminal earth via 5/5 CT, the HV side current can be supervised and guarantee the safety of operator.
Waveform deviation <3%        Non-load Current: <10%            Impedance voltage <20%

Over Current Ability: Continuous working for 300S under 120% rated current (0.6A), then thermal damage or distortion of the winding shall not be occurred.
Over Voltage Ability: Over voltage at 110% UH (330kV) for 60s., then it shall not happened any insulation damage for the testing transformer.
Noise:≤65dB                   Dielectric loss: <0.5%
Operating Time: 20min per day.
Protection: Equip with 0.6kV surge arrestors at test transformer exciting winding.
