Insulators in high voltage systems are subjected to various types of electrical stresses, including power frequency voltages and transient overvoltages (like lightning surges and switching surges). Different tests are required to evaluate their performance under these different stresses.
To test the insulator against HV surges caused by lightning, the test normally adopted is
