Tips: Protective device to be installed in a 5 kVA isolation transformer

1. Gas protection that reflects the internal faults of 5 kVA single phase 230V to 120V isolation transformer oil tank and oil surface reduction.
2. Longitudinal differential protection or current fast-trip protection that reflects the interphase short circuit of isolation transformer winding and outgoing line, the single-phase grounding short circuit of neutral-point solid ground winding and outgoing line.
3. Overcurrent protection that reflects the external interphase short circuit of step up/ dowm transformer and plays as the differential protection reserve of gas protection box (or current fast-trip protection).
4. Zero-sequence current protection that reflects the external and internal grounding short-circuit of the 5 kVA isolation transformer in the neutral-point solid ground system.
   Overload protection that reflects the symmetrical overloading of the transformer.
