KOEHLER K16175 Dielectric Breakdown Voltage of Insulating Oils

KOEHLER K16175 Dielectric Breakdown Voltage of Insulating Oils

Test Method
The majority of high-voltage transformers, cables, switchgears, transducers, capacitors, and rectifiers use insulating oils for insulating electrically live parts and to carry off thermal energy. The quality of the insulating oil must be checked at regular intervals to ensure a long equipment service life.
The most important requirement of an insulating oil is a high dielectric strength. Determination of the dielectric breakdown voltage of insulating oils provides an early detection method for any reduction in the insulating properties.
