IR SF6 Trader for Ultra High Voltage

2020-10-25IR values to be recorded at intervals of 15 seconds, 1 minute and 10 minutes. With the duration of application of voltage, IR value increases. The increase in IR is an indication of dryness of insulation. Absorption coefficient = 1 minute value/15 secs. value. Polarization index = 10 minutes value/1 minute value.
