ANORDNING FOR OVERVAKNING OCH KORREKTION AV SIGNALER

摘要

1532383 Voltage measuring BBC BROWN BOVERI & CO Ltd 5 July 1977 [7 July 1976] 28149/77 Heading G1U A voltage equal to the average of a plurality of input voltages is produced, delayed and compared individually with each input voltage. Any difference larger than a pre-set amount causes the corresponding input voltage to be disconnected. The system described is a redundancy system in which ideally the input voltages would be identical. Excessive differences indicate faults and the arrangement described prevents the average signal changing excessively when a fault does occur.
