“…He possesses a current interruption system and is used for the maneuvering and protection of circuits; this is due to its high isolation interruption capacity of overload currents above the nominal value as well as of short circuit currents. In agreement with previous researches, it can be affirmed that more than 40% of the maintenance cost of the substation equipment are spent in Circuit Breakers, and 60% of that amount is destined for general revision [6] and [11]. In this way, the predictive maintenance systems based on the continuous monitoring of Circuit Breaker parameters can provide significant reductions in those costs.…”

This work describes the experience obtained in the Circuit Breaker System Monitoring project executed for two Brazilian electric utilities, one of transmission and another of distribution. The project had as main characteristic the use of market available equipment and standardized communication protocols, inside of an open and flexible architecture, that allows its application to circuit breakers with different technologies and with different operating mechanisms and insulation systems.

“…Research regarding automated analysis of circuit breakers has been conducted since 1969 [14] to optimise maintenance and improve safety of personnel and the environment. The general consensus of a literature review performed by the authors revealed that a combination of parameters should be utilized to indicate the health of the breakers [15][16] [17], with the IEEE C37.10.1 guide [8] offering a variety of ways to measure these parameters. The main focus of the literature is that the opening and closing times, the SF 6 pressure and I 2 t are useful parameters that indicate mechanical wear, SF 6 leakage and interrupter erosion, respectively.…”

Control decisions within future energy networks may take account of the health and condition of network assets, pushing condition monitoring within the smart grid remit. In order to support maintenance decisions, this paper proposes a circuit breaker prognostic system, which ranks circuit breakers in order of maintenance priority. By monitoring the SF 6 density within a breaker, the system not only predicts the number of days to a critical level, but also incorporates uncertainty by giving upper and lower bounds on the prediction. This prognostic model, which performs linear regression, will be described in this paper, along with case studies demonstrating ranking breakers based on maintenance priority and prognosis of a leaking breaker. Providing an asset manager with this type of information could allow improved management of his/her assets, potentially deferring maintenance to a time when an outage is already scheduled.

“…Under the off-line way, the measured data will unavoidably have some deficiency for the real situation of the operating equipments, so the technique of monitoring circuit breaker is gradually developing from the off-line test to periodically online monitoring, as well as long-term online monitoring developing process. Realization to high voltage electrical equipments in real-time and online monitoring, and understanding the operational status of circuit breakers, in order to promptly take preventive measures, will play an active role for enhancing the reliability of the power supply and preventing an accident from occurrence [1][2].…”

The principle of an online monitoring and diagnosis system suitable for various kinds of High-voltage Circuit Breakers (HVCB) is presented in the paper. The system consists of distributed data acquisition devices, a communication system based on field bus, and a host based on B/S structure. The research presents the methods to select the main monitoring signals of high-voltage circuit breakers, to acquire data, and to calculate operational feature values, as well as realizes high-speed process to monitoring signals, valid online monitor to high-voltage circuit breakers, and fault diagnosis.
