IEEE C37.34e-1979, Switching Impulse Testing of Extra-High-Voltage Switches, Supplement to ANSI/IEEE C37.34-1971, IEEE Standard Test Code for High-Voltage Air Switches, updates information on switching surge testing of extra-high-voltage switches to conform with presently accepted standard conditions and switching-impulse wave shape. Additional information on standard deviations is included.<<ETX>>
This standard provides guidance in the switching surge testing of EHV air switches. For the design and safe application of EHV air switches, it is believed essential to have uniformity of test environment, test procedure, and interpretation of data in order to correlate data gathered in different laboratories and eliminate the wide variations that are apparent in test results.<<ETX>>
