9.1 Technological principles
9.1.1 Reliability, availability
A set of relays for electrical protection of rotating machines must have characteristics of reliability (probability of fulfilling its function at a given time) and availability (probability of fulfilling its function for a given duration) in line with the use of the machine it is intended to protect.
The high cost of repairing a high-power alternator or motor, as well as the costs incurred by loss of production or service, mean...
