The UR6TV integrates with the GE Universal Relay platform through modular backplane communication and numerical processing functions. The module supports IEC 61850 GOOSE and MMS messaging for deterministic relay-to-relay and station-level communication. The architecture provides configurable I/O density scaling through the UR chassis design and supports firmware flash compatibility within the applicable UR hardware revision range.
Voltage processing functions include RMS phase voltage calculation, sequence voltage measurement, frequency calculation, phase angle measurement, and loss-of-potential detection. The module processes PT input signals for undervoltage, overvoltage, synchronism verification, and voltage balance protection elements.
Frequently Asked Questions
Q: Does the UR6TV support hot-swap operation during relay operation? A: Hot-swap capability depends on the installed GE Universal Relay chassis configuration and approved maintenance procedure. Module replacement should follow the applicable relay service instructions.
Q: Which communication interfaces are available for system integration? A: The UR6TV supports Ethernet interfaces including 10/100Base-T RJ45 or 100Base-FX fiber options, along with serial RS485 and RS232 interfaces.
Q: What voltage protection functions are executed by the module? A: The module supports phase and neutral undervoltage, phase and neutral overvoltage, ground overvoltage, synchrocheck, phase sequence voltage, loss-of-potential detection, and frequency protection functions.
Field Installation Guidelines
Install the UR6TV within the designated GE Universal Relay modular chassis position according to the hardware configuration documentation.
Verify AC voltage input wiring polarity and phase assignment before energizing the relay system. PT secondary wiring should use appropriate shielded cable practices, with cable routing separated from high-current conductors to reduce electrical interference.
Connect communication wiring according to the selected interface type. Fiber optic communication should maintain proper bend radius and connector cleanliness. Serial communication cables should follow industrial grounding and shielding practices.
Confirm power supply voltage range before connection. Protective earth and chassis grounding should be installed according to the relay panel grounding design.
After installation, verify voltage measurements, sequence quantities, frequency values, communication status, and event recording operation through the relay configuration and diagnostic interface.
