The JED (S) H series SF6 gas insulated electronic voltage transformer is the development direction of instrument transformers. Compared with conventional instrument transformers, electronic transformers have a simpler insulation structure, smaller volume, and lighter weight; No iron core, no ferromagnetic resonance and other issues; Good anti electromagnetic interference performance; Large dynamic range and wide frequency response.

1. The maximum voltage of the equipment is 72.5-550kV, with a rated frequency of 50/60Hz;
2. The power frequency withstand voltage is 160-740kV, the full wave impulse withstand voltage is 320-1675kV, the cut-off impulse withstand voltage is 1930 kV, and the operating impulse withstand voltage is 1175 kV;
3. Rated gas pressure ≥ 0.45Mpa;
4. Secondary output: IEC 61850-9-1:2D41H
IEC 61850-9-1: Primary voltage x 100
