Overspeed Protection System
We have been designing and manufacturing a variety of electronic cards for more than two decades.
So far we provided more than hundreds of different types of cards to power plants, refineries and other industrial centers like modern electronic breaker drivers, steam turbine control, steam boilers control and etc.
The Overspeed Protection Device is a product developed by HANI ENERGY It is intended to be used for the overspeed protection of rotating equipment. This is an electronic over speed trip device designed, to provide reliable over speed trip protection for rotating equipment using magnetic speed sensors to determine rotational speed. This product is designed fully modular and is configured in a 19” rack, consists of 3 independent Monitoring Modules for each shaft and one Interface Module.
- Fast reaction time to over speed (15msec)
- Two Internal 2oo3 voting relays
- Isolated analogue outputs with scalable ranges for each monitoring module
- Peak speed detection and display
- Front panel TFT display
- One External-trip input
- Two alarm output
- One buffered output pulse
- Independent power input (18–30 V DC) for each Module
- The input can read magnetic pickup, proximity and hall effect sensors
- Hot module exchange
- Up to two shaft monitoring and trip on one rack
- Alarm management and event logger consist of:
- Speed deviation between input sensors
- Check for communication loss
- Out of range Setting Input
- Speed measurement processor failure
- Routine test performance
- Power Monitoring
- Configuration via PC and front panel LCD and keypad
