Regional geosystem monitoring presumes: ответ на тест 1056235 - Экология

A phase monitoring relay which ignores momentary voltage or phase failure has been launched by Carlo Gavazzi Electromatic.
Designated the Electromatic S-System Type 5074, the relay was developed as a result of frustrations in the British water industry where monitoring relays had the costly and annoying feature of switching alarms or shutting down equipment when a mere momentary loss or reduction in voltage of a phase was detected. The Electromatic solution has been to build a delay on de-energise timer into the relay unit so that a 10 second delay is experienced before the relay points release.
