UR8CH
GE Multilin UR8CH CT/VT Module
Product Description
The GE Multilin UR8CH is a CT/VT (Current Transformer/Voltage Transformer) module meticulously designed for installation within the UR series of universal relays. It serves as an ideal solution for system replacement or upgrade scenarios. This module’s primary function is to supply the relay with 3 – 1A/5A phase current transformers and a 1/5A ground current transformer.
In the realm of power systems, current transformers play a dual – role. They not only provide crucial data regarding the power system but also act as a safeguard by isolating the system from extreme currents and voltages. This isolation significantly extends the lifespan of the system and helps in reducing general maintenance costs. Additionally, they offer standardized output voltages, eliminating the need for extra auxiliary protection. Voltage transformers, on the other hand, enhance user safety and enable the reliable measurement of power system voltages.
The CT/VT settings of the UR8CH module are highly adaptable, allowing for the creation of unique protection schemes. These schemes can include differential protection, concurrent split – phase protection, and more, thereby augmenting the module’s versatility. Some versions of the UR8CH module are equipped with enhanced diagnostic capabilities. These features utilize advanced algorithms t
