Thnks anna .form voltech engineer

[@baranitechtamil3283]

welcome bro.

[@vijayvenkatesh9583]

bro one doubt, In case 1: 20 times fault current flows to the circuit how metrosil will block the high current ? As you said purpose of metrosil is to protect the circuit from Peak volatge.

[@baranitechtamil3283]

to block the high current stability resistance is used on series with relay

[@baranitechtamil3283]

yes

[@Eng853]

sir,what is difference between high impedance differential and low impedance differential protection?

[@baranitechtamil3283]

high impedance is differential current directly detected from CT to relay , Low impedance is differential current is calculated by relay according to the setting
