CR/R Grading Product for DC Bypass

High voltage capacitor Helicoidale pour DC Bypass
High voltage capacitor Helicoidale pour DC Bypass

RC-Grading Capacitors ensure the uniform distribution of DC voltage across the breaking chambers during switching operations.

CONDIS is able to provide, in a single unit, a combined solution including both resistance and capacitance, easing the installation and minimizing the volume. They are installed on high voltage bypass multi-chamber Circuit Breakers.

RC-grading capacitors are available with either a porcelain or a composite insulator that is in full compliance with IEC 60815.

The design of high voltage CR/R-Grading Capacitors is usually customer-specific. CONDIS’ Capacitor technology offers a high flexibility and will therefore allow a large customization to meet specific Circuit Breaker mechanical and electrical needs.
