Power Frequency Over Voltage Withstand Test. The power system may experience different temporary power over voltage conditions may be due to sudden cut of load from the system, wrong operation of online tap changer, insufficient shunt compensation in the system, etc. Dielectric test on auxiliary and control circuit. There may be abnormal over voltage condition in the auxiliary and control supply circuits, too. Hence, the auxiliary and control circuits of breakers should also be gone through short duration power frequency voltage withstand test. Measurement of the resistance of main circuit. The resistance of main circuit is measured from DC voltage drop across the circuit. In this test, direct current is injected to the circuit and corresponding voltage drop is measured and from this resistance of the circuit is measured. Tightness Test. This test is carried out on mainly gas insulated switch-gear. In this test, leakage rate is measured. This test ensures the desired lifespan of the switchgear.
