High voltage arrester
WebLet V RM be the maximum permissible residual voltage for the complete unit. The ratio V RM /V 1 = r, is defined as a multiplying factor of the rating for the residual voltage test, which depends on V 1.The “ diverter ” is said to pass the test, if High Current Impulse Test on Surge Arresters: This test is also done on pro-rated arrester units in the range of 3 to 12 kV. WebHitachi Energy has 100+ years of experience in designing and manufacturing surge arresters for protection of electrical devices from all kind of overvoltages. Surge arresters are used for protection of electrical equipment from all kind of overvoltages caused by lightening or switching operations.
