Answer Posted / gova
Diff relay compares the input current and output
current that flows through the equipment and if there is
any difference between them,then the relay will sense the
difference of two currents (called differential current)
and trip the equipment protected if the differential
current exceeds the setting.
diff relay used in transformer,Generator,lines,motors etc.
what is MDB.pl abbreviate it.
