The principle of the method specified is pouring the insulating liquid into the test cell, increasing a power-frequency a.c. voltage at a constant rate, monitoring the appearance of discharges by an appropriate partial discharges measuring device, recording the voltage at which theapparent charge of the discharges is equal to or larger than 100 pC. At least 10 PDIV measurements are made on each of two different fllings of the cell. The average of the mean values of the two series is taken as the result. The method is applicable to all types of insulating liquids used in medium and high voltage equipment.
