WebTests performed using AC voltages and currents were done at a power frequency of 60 Hz. It is a generally accepted conversion that dielectric tests done at different power frequencies are considered equivalent if the number of cycles is the same. In this way, tests performed at 60 Hz include 20% more cycles than would a test performed WebNOTE 1— 2In general, this standard applies to all high voltage power switchgear designed to IEEE C37 series. Exceptions include low- voltage standards (less than 1 000 V), and protective relay standards.
