MINII Ground Protection System The MIN II, a member of the M II family
of protection relays, is a microprocessor
based relay that provides ground
directional protection on distributed
networks at any voltage level and
backup/auxiliary ground directional
protection for transformers, generators
and motors. Additionally, it can be used to
create a separate directional comparison
ground scheme in pilot channels used for
distance relaying.  Reduce troubleshooting and maintenance cost - Event
recording, and analogy/digital oscillography Design flexibility - Easy to use programming logic Access to information - Modbus® RTU communications Configurable logic, curves, digital I/Os, and LEDs Follow technology evolution - Flash memory for product field
upgrade Asset monitoring - Breaker health, and breaker failure
protection Two settings groups Password protection for local operation Automatic display of last fault information AC/DC power supply Access via front panel keypad or communication links EnerVista™ compatible Isolated RS232 port  Directional ground protection at any voltage level Backup/auxiliary protection for line schemes Component relay for transformers, generators and motors  2 ground IOC (high and low) units for grounded systems 2 ground TOC (high and low) units for grounded systems 2 directional units for grounded systems 2 directional overcurrent units for Petersen coil 2 directional overcurrent units for isolated ground Directional comparison: scheme logic 4 preconfigured overcurrent curves (ANSI or IEC) Configurable breaker failure protection Configurable I/O 6 outputs: trip, service, 4 auxiliary  32-event record, analog/digital oscillography KI2 counter for breaker maintenance Ground current metering Monitoring of the last 5 trips information from the display  2x16 character LCD display 6 LED indicators, 4 configurable in function and color Front RS232 and rear RS485 ports using Modbus® RTU
protocol up to 19,200 bps EnerVista™ software - an industry leading suite of software
tools that simplifies every aspect of working with GE Multilin
