Percentage biased Differential Relay Testing System is a very significant product for Power System lab for electrical students. 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 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.
‘Nvis 8015 is designed in such a way that-students can explore about different sections of Differential Relay and can operate it to learn its functioning. It also includes built-in variable supply and fast response measuring instruments which makes the measurement system very precise.
