Differential Relay Testing System
Differential Relay Training System is a very significant product from power System lab for Electrical students. Differential Relay has operating coil connected in series with small choke and capacitor forming a series resonant circuit.
In a differential protection scheme Students can learn the phenomena of differential relay like under normal conditions, or for a fault outside of the protected zone, current i1 is equal to current i2.
Therefore the currents in the current transformers secondary’s are also equal, i.e. i1=i2 and no current flows through the current relay. If a fault develops inside of the protected zone, currents i1 and i2 are no longer equal, therefore i1 and i2 are not equal and there is a current flowing through the current relay.
