Proper arc extinction by the compressed gas in the circuit breaker is veryimportant. When the pressure becomes too low compared to the required value, thecircuit breaker operation shall be blocked to minimize the risk of internal failure.Binary information based on the gas pressure in the circuit breaker is used as an inputsignal to the function. The function generates alarms based on the receivedinformation.Section 14 1MRK 505 370-UUS AMonitoring440 Busbar protection REB670 2.2 ANSIApplication manual
