An Equivalent Condition Score Method for the Calculation of the Failure Rate for Power Transmission Equipment with Condition Maintenance

In this paper, we propose a new method, namely equivalent condition score (CS) method, to calculate the failure rate of power transmission equipment with condition maintenance. Through the conversion of the CS evaluated after maintenance, we can investigate the effect of maintenance on the failure rate, and then calculate the failure rate of the equipment. The effectiveness of the proposed method is verified by field maintenance data. As shown in this paper, the equivalent CS method has a simplified calculation process and specific physical meaning.
