Task:
System faults and failures in mobile communications transmitter stations as a result of poor power supply quality (undervoltage, phase failure) should be detected and indicated.
Solution
The voltage relay reliably detects phase failures and undervoltage below the configured threshold and indicates the power supply fault at the control centre via the internal communication system. An emergency generator is switched on, a service technician is sent to the site, or an alternate radio station is taken into operation.

Use/value:
- Rapid detection of system faults, and therefore improved mobile communications network quality
- Compact size and separate display for the fault for each phase, configurable undervoltage threshold depending on the customer and system needs
