The disturbance recorder module type SPCR 8C27 is a high-capacity, fully digital data recording module, which is used together with protection relays and terminals of the SPACOM product range.
The recorder module provides a tool for the network operating and design personnel to analyse the performance of the power system, its protection equipment and other components before, during and after a network disturbance situation. Fast identification of a network problem and correct assessment of the network behavior enable rapid corrective measures to be taken, sometimes even before a problem develops into a major network fault. Thus high power system reliability and availability can be achieved to satisfy society’s demand for a better quality of power supply. The recorder module also provides basic information for improving the planning and construction of future power systems.
- Records data to be used for network operating analyses of the performance of the power system, its protection equipment and other components before, during and after a network disturbance situation
- Versatile digital disturbance recorder module for recording various phenomena in the electric power system, especially during fault conditions
- Can be plugged into the location of any protection relay module of the SPACOM product range
- No separate wiring for measuring signals or power supply needed, because the recorder module is energized and powered from the host relay
- Fully self-contained recorder module, no protection relay modules needed for the function
- A total of eight analog channels and eight digital channels can be supervised by one disturbance recorder module
- Total recording length 12 seconds, when all channels are recorded. Extendable to 55 seconds
- Triggering by overcurrent, overvoltage, undervoltage or by rising or falling edge of a binary signal
- Triggering also possible via a serial communication command given manually with push-buttons on the front panel or automatically at certain time intervals
- Time-tagged events obtained from a built-in real-time clock with battery back-up
- Maximum and minimum values of voltages and currents recorded in a separate limit value register
- Events such as triggering, exceeding of limit values and changes in binary signal status are recorded in a log register
