Numerical Capacitor Bank Protection Relay – GKCBR

Next-Gen Protection for compensation of reactive power

GKCBR is a dedicated capacitor bank protection relay perfectly aligned for measurement, control, and protection of the capacitor banks, which are used for the compensation of reactive power in railway power distribution systems.

GK Power, an RDSO-approved leading manufacturer in India, offers a numerical feeder protection relay at the industry’s latest technology. Enhanced safety by reducing hazards with safety-conscious testing of IEC 60255-1, IEC 60255-26, and IEC 60255-27, this relay unleashes its own full potential of working in hard environments with ingress protection of IP54.
