Grading Capacitors — grading (shunt) capacitors for circuit breakers up to 800 kV
Grading Capacitors equalize the voltage across the interrupters of multi-break HV circuit breakers rated up to 800 kV. They are also used for HF communication and for reducing transient overvoltages.
- Voltage class
- up to 800 kV
- Insulation
- oil-paper
- Purpose
- voltage grading across breaker interrupters, HF communication, reduction of switching overvoltages
- Design
- built to the mechanical and electrical requirements of a specific circuit breaker
Price, availability and lead time on request. We help with analogue selection, customs clearance and delivery.
Description
The capacitor insulation is oil-paper. Each capacitor shunts its own interrupter, so the voltage is distributed evenly between the breaker interrupters. The same units reduce switching overvoltages and serve for HF communication. The capacitors are built to the mechanical and electrical requirements of a specific circuit breaker.
