| Abstract: | The necessity of installing phase to phase fault protection on LV side of transformer is presented in this paper by analyzing the protection capability of phase to phase impedance protection on HV and MV sides of 500kV transformer against phase to phase fault on its LV side. It also gives some advice on the arrangement pattern of the protection as well. |
