BDV (BREAK DOWN VALUE)

Break Down Voltage (BDV) is a characteristic of an insulator that defines the maximum voltage difference that can be applied across the material before the insulator collapses and conducts...........

TAN DELTA (Dielectric Dissipation Factor)

The Dielectric Dissipation Factor is the ratio of power dissipation in the transformer oil in watts to the product of the effective voltage and current in volt-amperes..........

FLASH POINT

Flash Point is the temperature at which the oil gives off so much of vapour that this vapour, when mixed with air, forms an ignitable mixture and gives a momentary flash on application.........

WATER CONTENT

One of the most important functions of transformer oil is to provide electrical insulation. Any increase in moisture content can reduce the insulating properties of the oil, which may result in dielectric........
