“…While the SSE is large, Equation (8) is still an effective equation for determining the permissible interruption CIRCUIT BREAKER CONDITION-BASED MAINTENANCE 635 number at various interrupted currents. The optimal fitting curve is plotted in Figure 7 in which Equation (8) can offer the nearly same maintenance data provided by the manufacturer. The fact can also be verified by checking the second and third columns of Table IV.…”

SUMMARY The electrical circuit breaker (CB) is one of the absolutely essential devices in the electrical power system. The evaluation of CB condition and its reliability gain on importance. The contact wear of the CB monitored by Intelligent Electronic Device plays a crucial role in the condition‐based maintenance (CBM). The present contact wear maintenance of the CB is based on the maintenance data provided by original manufacturers to compute the value of the accumulated contact wear. However, the evaluation of the contact wear always has a quite error. It may lead to over‐maintenance or under‐maintenance commonly found in maintenance planning and scheduling. Little literature has been down on the issue. By utilizing the modified hybrid Nelder–Mead simplex search and particle swarm optimization (PSO) algorithm, the paper proposes a curve‐fitting technology to obtain an optimal contact wear equation for realizing the CBM of the CBs. The presented optimal contact wear equation minimizes the sum of squared errors that can be programmed in Intelligent Electronic Device. An effective CBM planning can enhance electricity substation reliability and cut maintenance costs. Compared with the conventional Nelder–Mead simplex search and PSO and PSO algorithms, two case studies are given to verify the effectiveness of the proposed method. The work may provide some valuable references for the related workers and researchers. Copyright © 2015 John Wiley & Sons, Ltd.

Abstract-There is a need for a new survey of conditionmonitoring methods for circuit breakers and disconnectors, since during the last two decades less than ten surveys have been carried out. The paper presents several statistical surveys and analyses. The methods of condition monitoring found are reviewed and classified according to the different types of failure identified in the surveys. Some research gaps are identified, such as the prediction of the degradation of the contacts, the signal processing of coil and motor currents and the switching.
