About the UR-8HH
General Electric Multilin’s UR-8HH is a CT/VT module intended for installation in the Universal Relays series. It provides the relay with 1A/5A ground CTs and 3-1A/5A phase CTs, allowing the relay to scale down current ratings and voltage ratings to a value that enables the relay to monitor these system conditions and output data for user review. The data can then be employed for protective system functions executed by the relay itself. This data can be viewed through the relay’s liquid-crystal display or more efficiently through Multilin’s EnerVista UR software program.
EnerVista UR also allows efficient configuration of settings related to the CT/VT module, allowing for highly customized schemes that address needs unique to each individual user’s system. Additionally, the streamlined design of EnerVista UR allows users to easily review data in a beautiful, well laid out user interface. EnerVista’s Viewpoint UR Engineer also features a drag-and-drop environment that allows for rapid commissioning of the relay and associated modules.
Prospective buyers concerned about installation time will find that General Electric has designed the Universal Relays series with scalability in mind. The faceplate of the device can be unhinged (on both the enhanced and basic models of the relays) to allow access to the module bay, and Multilin provides a vast amount of information and diagrams on proper module wiring in their various product manuals.
