About the T60-E00-HCH-F8F-H6T-M8F-PGT-UXX-W6T

Equipped with advanced asset monitoring, General Electric Multilin’s T60-E00-HCH-F8F-H6T-M8F-PGT-UXX-W6T is a Transformer Management Relay. The microprocessor-based unit protects three-phase power transformers of any size, offering protective functions such as magnitude and phase shift compensation, instantaneous differential protection, and under/overfrequency protection. 

The Direct I/O messaging feature of the relay enables high-speed communication between different UR relays. It provides communication between up to 16 UR relays in either redundant or single rings. Direct/IO messaging functions can also be used in special protection schemes such as advanced interlocking and generation rejection. The relay also allows for real-time diagnostics of communication channels with its built-in continuous channel and loop monitoring abilities.

Required maintenance is minimal for the T60-E00-HCH-F8F-H6T-M8F-PGT-UXX-W6T relay. As a microprocessor-based relay, it does not experience a large amount of change over time. GE Multilin reports that the expected life of a Universal Relays device is approximately 20 years (if the device is manufactured more recently than June 2014). This, of course, is only true when the relay is properly installed within the recommended environmental parameters. 

GE Multilin recommends that users perform a variety of tests when commissioning the relay to ensure proper functionality. One of these tests is the differential characteristic test, which compares magnitudes of LV and HV current in real time. Users should ensure the test does not cause temperatures to exceed associated thermal ratings. Multilin has a number of resources on their website that users can reference to ensure proper function during the testing process.
