Capacitance and Tan Delta

What is capacitance? Two conductors which are separated by a distance can store an electric charge between them. Capacitance describes the ability of two conductors, separated by an insulating material, to store charge. Thus all the insulating materials are dielectric and are supposed to behave as capacitor when connected to line and earth. Ideally the […]

Dielectric Strength of Transformer Oil

What is dielectric strength of transformer oil? The dielectric strength of transformer oil is also known as the breakdown voltage (BDV) of transformer oil. Breakdown voltage is measured by observing at what voltage, sparking strands between two electrodes immersed in the oil, separated by a specific gap. A low value of BDV indicates presence of […]
