The SRcheck is a modern, small-scale measuring system that can be placed anywhere in the grid. It reliably registers all received ripple-control signals and their voltage levels.
- Three-phase measurement input
- Digital filtering of ripple-control signals via micro controller
- Processing of all established ripple-control systems and their specific pulse patterns
- Optional Swistra-functionalities
- Individual definition of the performance of the feedback receiver in case of power failure and its re-establishment
- 3 freely selectable, potential-free outputs with optical display (LED)
- Interfaces: USB, Ethernet, RS232, microSD card
- Analogue voltage output 0-10 V (optional)
- Under frequency detection (optional)
There are 3 potential-free, freely programmable outputs. Depending on the requirements, each received telegram pulse or the DECABIT 3 seconds signal can be confirmed. It is also possible to use the measurment input for the recognition of a power failure and to use a output contact for alarming purposes.
The output contacts are equipped with semi-conductor relays. These work free from wear and loss.
LEDs visualize the switch position of the outputs.
The SRcheck is programmed via its USB-interface. All functions can be controlled via the
programming and analyzing software SRanalyzer.
Each received ripple-control telegram is gauged with 5 kHz, i. e. every 0.2 ms, and recorded by the unit.
In addition to the bit-information, the respective signal voltage levels are also being recorded.
Depending on the memory capacity of the microSD-card that is being used for data
storage, all ripple-control telegrams can be stored over a period of several years.
Measurement data can be read out via the existing interfaces and analyzed with the SRanalyzer software and processed further using Excel. The RS232- and the Ethernet-interfaces are intended for remote evaluation and remote control whereas the USB-interface serves for a comfortable parameterization and on-site analysis.
Due to the program stored in the control unit, the control receiver can monitor whether the individual commands have been transmitted correctly and, in case of a missing or invalid telegram, send out an alarm or trigger an automatic repetition of the command.
