Proper arc extinction by the compressed gas in the circuit breaker is veryimportant. When the pressure becomes too low compared to the required value, the circuitbreaker operation shall be blocked to minimize the risk of internal failure. Binaryinformation based on the gas pressure in the circuit breaker is used as an input signal to thefunction. The function generates alarms based on the received information.Section 14 1MRK 505 337-UUS -Monitoring414Application manual
