RC-Grading Capacitors for HVDC Bypass switchgear

Resistance or combination of resistance and capacitance compose the RC-grading capacitors; they are installed on high-voltage bypass multi-break circuit breakers.

RC-grading capacitors ensure uniform distribution of DC and AC voltage components across the breaking chambers during the switching operation.

RC-grading capacitors are available with a porcelain or a composite insulator. All standard porcelains are equipped with single or alternating long-short sheds and are in full compliance with IEC 60815.

The design of High-voltage RC-grading capacitors is usually customer-specific. Maxwell CONDOR technology offers a high flexibility and will therefore allow for a large customization to meet specific circuit breaker mechanical and electrical needs.
