Electrical Reliability and Availability Calculation
Availability is the total amount of time that equipment is actually operating compared to the time it is planned to operate. Availability is also the probability that a piece of equipment or system will work properly at a given time (not the duration).
Reliability is the probability that an asset will perform without failure over a specified period of time under normal operating conditions. Another definition is the probability that a system will not fail or require repair when it is needed.
