Differential Pilot Wire Protection is simply a differential protection scheme applied to feeders. Several differential schemes are applied for protection of line but Mess Price Voltage balance system and Translay Scheme are most popularly used.
Die-electric test on Circuit breaker: These tests are performed to check power frequency and impulse voltage withstand capacity. Power frequency tests are kept on a new circuit breaker, the test voltage changes with a circuit breaker rated voltage. In impulse tests, impulse voltage of particular value is employed to the breaker.

Short circuit current is the current passing through a solar cell when voltage is zero across the solar cell, which happens when a solar cell is short circuited. Usually it is denoted Isc. solar cell have short-circuit currents between about 28 mA/cm² and 35 mA/cm²
