Surge Capacitors designed for the most demanding conditions
The 2GUS surge capacitor offer the user high transient voltage withstand, long life design, low loss dielectric and rugged construction.
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 of Surge Capacitors:
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.
