Numerical Protection Relay

Model Number

GD & G5R Series

Description

GD/G5R series protection relays of P&C Tech are micro-processor based protection relays.GD/G5R series cover all protection relays through distribution networks including switchboardand distribution panel board, and the accuracy is enhanced and the reliability to external noiseis improved. GD/G5R series are applied to both line conditions of 3P3L and 3P4L, and a single relaycombines multiple phase / protection elements.
