Capacitor

Steep fronted waves (lightning or switching surges) can cause damage to the turn to turn insulation of rotary machines and transformers. These capacitors provide premium surge protection for high voltage motors and generators . They can also be used in combination with surge arresters for added protective capability.

Connecting surge capacitors line to ground at the motor terminals prevents this damage. For a more comprehensive protection scheme, surge capacitors may be used in conjunction with surge arresters. This surge pack modifies both the wave shape and magnitude.

Installation and maintenance
Surge capacitors can be located indoors or outdoors and can be mounted vertically or horizontally.
Suitable for an ambient temperature not exceeding 50 ^oC, they are virtually maintenance free, needing only occasional cleaning of bushings and paint surface and ensuring connections are correctly tightened.

MSP - Motor Surge Protection
An enclosed package with surge capacitor and lightning arrester. This device provides premium surge protection of high voltage motors and generators with a surge capacitor and station surge arrester combination package. The unit is factory assembled in a NEMA 3R outdoor enclosure.
