Thyristor Valve Capacitors
The Thyristor Valve Capacitor (or valve section capacitor) is fitted on Thyristor Valves for voltage conversion . Its function is to assist the system with the filtering of high frequency transient voltages produced during the transformation of the AC voltage to the DC voltage or vice-versa.
The Thyristor Valve capacitor is connected in parallel with series thyristor, damping resistors/capacitors and di/dt limiting reactors.
CONDIS’ Capacitors for Thyristor Valve applications are self-healing dry capacitors (without oil), mounted in an epoxy resin insulator.
