Description
Tele Haase NA003-M64 Grid and System Protection Relay measures grid voltage frequency with 1-2 tie switches that ensure the actual disconnection from the main
- Functional Description
- Depending on the configuration selected, the device can handle several monitoring functions at the same time
- After exceeding a threshold value, the device switches off after a response-delay that is defined especially for each threshold value
- When the test function or the remote shutdown is activated, the device switches off immediately
- Only once all monitored parameters are within the permissible limits and the remote shutdown deactivated does the device switch back on after a defined turn-on time
- If not specified otherwise, the nominal voltage is 230 V / 400 V and the nominal frequency 50 Hz
- Features
- Simple implementation through pre-defined setups for country-specific standards and guidelines with parameters that can be set within a wide range
- Wide nominal voltage and nominal frequency range, configurable nominal voltage
- Additional "Open setup" for free, practically unlimited parametrization in the field
- Single-fault tolerance
- Cyclical self-test
- Monitoring of the connected section switch
- Remote shutdown
- Loss of mains detection (RoCoF, PShift, phase voltage)
- Test function with the determination of the turn-off time
- Monitoring of 1- and 3- phase grids for low and medium voltage grids
- Error memory with a timestamp (50 entries)
- Password protection and ability to seal
- Random turn-off thresholds and turn-on times for non-controllable energy producers (e.g. CHP)
