Frequently Asked Questions about UR-3PH
Which model of the UR series of universal Multilin relays is the UR-3PH a replacement panel for?
The UR-3PH model is the designation for a replacement front panel of the T60 GE Multilin universal relay. The T60 is the transformer management relay for medium to large transformers. This transformer protection system is appropriate for power transformers that need current differential function. This T60 Multilin relay allows for magnitude reference winding selection that is user defined. The T60 is also able to adjust to phase shifts automatically for differing types of winding connections. The replacement front panel replicates the display components of the T60 front panel has indicators for up to eight groups to show which settings are in use at the current time. Breakers 1 and 2 also have indicators for open, closed, or trouble situations. The status indications for trouble, test mode, trip, and alarm conditions are also found on the top left of the front panel. The front panel of the UR series Multilin universal relay allows the user to view the current function and communication status of the relay with complete accessibility to the differing functions and modes. Each UR relay shows similar front panel features for this purpose.
