GE Fanuc T35 Transformer Microcomputer Protection Monitoring Device

GE Fanuc T35 Protection Monitoring Device Overview

Unique transformer protection function, monitoring simulation and RTD inputs by double principle (differential and direction), and the application of CT saturation detection improve security - similar patent solution in the principle of first-class, need only 2 ms can make right judgment is not affected by the saturation current through the compact design to reduce installation space needed - multifunction device integrated protection and control functions, programmable buttons and status leds and communication interface maintenance cost saving maintenance process is simple and modular structure, common hardware, reduce spare parts inventory, plug and play module.

Use high speed communication to reduce wiring and installation costs - relay to relay interactions through inter-relay input-output switching. Efficient and flexible choice and information access to a variety of communication protocols of application flexibility - multiple I/O, programmable logic (FlexLogicTM), modular design and can be customized protection and control functions of circuit breaker monitoring - through the analog I/O, a wide range of measurement, the circuit breaker, arc current and working condition monitoring circuit breaker tripping counter reduce system events analysis time and costs - the order report, wave record, data record, IRIG - B time synchronization.
