Break down voltage is measured by observing at what voltage, sparking string between two electrode immersed
in the oil, separated by specific gap. low value of BDV indicates presence of moisture content and conducting
substances in the oil.
In this kit, oil is kept in a pot in which one pair of electrodes are fixed with a gap of 2.5 mm (in some kit it 4mm) between them.
