To understand the “Breakdown Voltage” (BDV) of transformer oil, we first need to get introduced to dielectric strength. Dielectric strength is defined as the ability of the oil to withstand electrical stress without breaking down. Here, breaking down refers to the failure of insulating properties.
Now, let us move on to our main question and try to understand the BDV of transformer oil.
Oil stored in drums loses its dielectric strength and must be tested and treated before use in electrical equipment. The breakdown voltage test of transformer oil is crucial for the smooth operation of the transformer.
A periodical BDV testing of the transformer oil ensures the quality and healthiness of the transformer oil. Breakdown voltage is determined by observing the voltage at which a specific gap separates sparking strands between two electrodes immersed in oil.
A low BDV value indicates that the oil contains moisture and conducting substances. As per the International Electrotechnical Commission (IEC), the minimum BDV value of transformer oil should be 30 kV.
The Breakdown Voltage is the primary indicator of the health of the oil. It is a popular and important transformer oil test because it:
The breakdown voltage refers to the limit voltage of the capacitor; above this voltage, the dielectric in the capacitor will fail. The rated voltage is the voltage that the capacitor can withstand over time and is less than the breakdown voltage.
Capacitors function properly at rated voltage and safely at voltages no higher than the breakdown voltage.
The breakdown voltage is the voltage at which the dielectric fails. It indicates the health of the transformer oil. Overall, the breakdown voltage of transformer oil is important because it allows the transformer to operate smoothly and prevent failures.
BDV results are better in dry and clean oil than with moisture and other conducting impurities.
