Surge capacitors CHDSU
Protection for motor and transformer windings
Steep fronted waves (lightning or switching surges) can cause damage to the turn-to-turn insulation of rotary machines and transformers. Hitachi Energy surge capacitors provide premium surge protection for high voltage motors and generators. For a more comprehensive protection scheme, surge capacitors may be used in conjunction with surge arresters.
Applications
- Protection of motor windings
- Protection of transformer windings
Why Hitachi Energy?
- High transient voltage withstand
- Long life design
- Low loss dielectric
- Rugged construction
