| Abstract: | This paper presents a multi-purpose impedance relay for U. H. voltage transmission lines and the analyses of its static and dynamic characteristic. It is shown that under different system fault conditions the relay can correspondingly perform the characteristic of mho relay or offset mho relay to cope with the demand of three-phase auto-reclosing when the P.T.s are installed on the line side. The dynamic characteristic of the relay increases its tolerance to fault arcing resistance and it can be used on transmission lines with capacitance compensation. |
