Product Description

General Electric Multilin’s UR-8RH is one of many CT/VT modules designed for operating in the Universal Relays series. Providing the relay with sensitive ground 8CT and enhanced diagnostics, this particular module is extremely capable and effective. The sensitive ground input feature is ten times more sensitive than the standard unit, detecting faults with ease.

The module relies on a system of configured setpoints to run, which can be edited more easily using Multilin’s EnerVista UR software program, though using the keypad and LCD in tandem remains an option as well. The module does include Plug & Play capabilities, relying on a set of fairly standard settings to begin functioning at an optimal pace.

UR6PH

For users uncertain if their system already contains the UR-8RH (or one of the many other CT/VT modules available) they should examine their order code and compare it to the order tables found in General Electric Multilin’s user manuals. Models including an “XX” in the segment of the model number associated with CT/VT modules do not offer the CT/VT functionality, making this unit a good purchase if suitable for the user’s system needs. Modules containing one of the actual order codes, such as the 8RH, makes purchasing this module ultimately unnecessary.

Frequently Asked Questions about UR-8RH

How is the UR-8RH unique to other CT/VT modules that may be incorporated into a General Electric UR Series universal relay such as a L90 line differential relay?
The UR-8RH is of the newer generation of CT/VT modules. It is unique in that it is equipped with sensitive ground 8CT components with enhanced diagnostic abilities. These newer CT/VT modules must be used with a firmware version 4.0x and greater. It is also best to pair a new CT/VT module with a corresponding new CPU to avoid an error such as the hardware mismatch error. This GE Multilin UR-8RH uses the sensitive ground feature in order to provide ground protection to the universal relay in the case where grounded systems are high-impedance. This high-impedance detection of ground faults provides reliably quick detection of these situations, which in many cases are cased by a conductor that is down. These CT/VT (current transformer and voltage transformer) modules also afford the Multilin universal relay with up to 24 analog CT and VT signals. These signals are used to monitor the AC power lines. This ability is important for the universal relay depending on its end stage application. Some UR relays will function to provide transmission and distribution applications whereas others may fall into the generation category.
