i know that megger is used in marine.but how its been used and please give me other megger application in detailedthanks for answer
In electrical testing we megger equipment. A ac voltage 600 volts is induced one a piece of electrical equipment like a transformer and the impedance is measured. The megger measured AC resistance/impedance vs normal dc resistance that volt meter measure. The higher voltage gave a more accurate measure of impedance. Equipment with defective insulation, would have a lower impedance.
