Answer Posted / sukhvinder
differential relay which operates on two or more similar
quantities i.e voltage,current.
in this relay under normal condition, no voltage flow
through coil i.e vi+v2=0 but in abnormal the differnce of
two voltage i.e v1+v2 will not equal to zero. so that
voltage will flow through the coil further protection of
equipment/devie/system etc.
