These capacitors are designed for protection of large
rotating machines such as motors & generators. At the time
of over voltage during electric storms produces surges to
electrical equipments connected to system. The voltage
stress between turns of multi turn coil sets a limitation
and surge voltage causes breakdown of turn to turn
insulation resulting in short circuited turns.
