Product Overview
The UR-8MH GE Multilin CT/VT 8M Sensitive Ground 4CT/4VT Module is a modular current/voltage transformer interface unit designed for GE Multilin Universal Relay (UR Series) systems. It provides precise scaling of analog signals from current transformers (CTs) and voltage transformers (VTs), along with sensitive ground fault detection, enhancing the relay’s protection and measurement capabilities. The module plugs into UR relay chassis to expand protection functions such as generator, transformer, motor, and feeder monitoring, while advanced diagnostics help maintain signal integrity and system reliability.
