GMRKONUT
Overview
GMRKONUT is a grid monitoring and protection (Loss of Mains) relay developed for residential photovoltaic generation systems.
Grid monitoring and controlled reconnection
It disconnects the generation system from the grid in overvoltage, undervoltage, overfrequency, underfrequency or loss-of-mains conditions. Adjustable delays allow controlled reconnection when grid parameters return to nominal limits.
Protection functions
- 27U undervoltage and 59 overvoltage
- 81U underfrequency, 81O overfrequency and 81R rate of change of frequency (ROCOF)
- BF breaker failure, 74TCS trip circuit supervision and ARF automatic reclosing
Touch panel and indicators
The 2.8-inch TFT-LCD touch panel provides System, Alarm and Settings menus. Protection parameters can be adjusted, and alarm conditions can be recorded and monitored in real time. LEDs provide power, fault and position information.
