Standard For Power Frequency Withstand Voltage Test Of Drop-out Fuse
Date: | Read: 2
drop out fuse The base and insulator are subjected to power frequency withstand voltage for 1 minute each between phases and to ground, and the presence or absence of discharge or flashover is recorded under dry and wet test conditions. The test is performed in accordance with the requirements of GB15166.3 and IEC 60282-1. During the test, the applied voltage, duration, altitude correction factor and discharge phenomenon are recorded. The test data are used as the basis for factory inspection and type test.
