Definitions For the purposes of this document, the following terms and definitions apply. The IEEE Standards Dictionary Online should be consulted for terms not defined in this clause.” continuous monitoring: Monitoring installed for uninterrupted consecutive sampling or observing circuit breaker condition. Sampling, calculation, or processing time may not yield real-time results. Ability to monitor some characteristics may only be possible when the circuit breaker operates. NOTE- -The monitored circuit breaker can be in the energized or de-energized state, with manual, or automatic on-line, periodic, or continuous monitoring. diagnostic analysis: Application of tools such as artificial intelligence (including expert systems, neural nets, and fuzzy logic) to analyze the outputs from periodic or continuous monitoring. These tools may relate present or recent data to historic information. They can, however, provide engineering conclusions based on the measured values. NOTE- See also: IEC 60812. failure characteristic: (A) A description of the conditional probability of failure against operating age for an electrical or mechanical item; (B) The evolution of how a failure develops over time.
6.2 Control circuits The following control circuit components and operating conditions should be accessible for effective monitoring: a) Trip circuit integrity using established methods: Detect open trip circuit and rising circuit resistance. b) Close circuit integrity using established methods: Detect close trip circuit and rising circuit resistance. c) DC control voltage: Voltage level, Detect abnormal control voltage. d) AC control voltage: Voltage level, Detect abnormal control voltage. 6.3 Operating mechanism The following operating mechanism components and operating conditions should be accssible for effective monitoring: a) Mechanical quality- opening time: Detect mechanical and lubrication concerns b) Mechanical quality- closing time: Detect mechanical and lubrication concerns
