Which
is the main relay for protecting up to 90% of the transmission line-length in
the forward direction?
Directional over-current relay
Mho relay
carrier-current
protective relay
Impedance
relay
Mho relay
Which
is the main relay for protecting up to W0% transmission line-length in the
forward direction Mho relay.
Mho
relay used in long transmission line.
Mho
relay is inherently a directional relay as it detects the fault only in the
particular direction.
Hence,
the correct option is (B).
