HGTS 350KV/250KVA Gas Insulated Test Transformer

Mode: HGTS 350KV/250KVA
Insulation cylinder, fixed type                         Gas insulated: SF6 gas insulated
Single phase, 50Hz                                            Rated capacity: 250KVA
Rated voltage:     low voltage: 2*0.6KV           high voltage: 350KV
Rated current:     lv current: 2*208.3A           hv current: 0.714A
LV winding can be in both serial and parallel connection: in serial connection: hv output is 175kv/1A; in parallel connection, hv output is 350kv/2A
No load current: ≤10%                 Impedance voltage: ≤8.5%               Waveform distortion: ≤3%

Over current ability: working for 1 min under 120% rated current without any heat damage and distortion to test transformer winding;
Over voltage ability: working for 1 min under 110% rated voltage, without any insulation damage to test transformer, at this moment, waveform distortion is ≤5%;
PD level: < 2pC under 100% rated voltage
Working time: working for 60 min under 100% rated voltage and current, temperature rising of transformer winding is ≤65K;
Protection: among transformer exciter installed 0.6KV MOA.
