通常，在各种功率范围和占空比的类别内存在许多类型的旋转电机和变压器。这些机器在工业或民用条件下运行。事实上，每台机器最终都可能发生故障，损坏和损失都可能发生。因此，有必要评估某些类型的电机及其子系统的故障率及其分布。本文提出了一个分析的基础上公开可用的数据，总结和比较的结果，从研究中已经进行了几年。在本文中，重要的机器的子系统的故障率识别。故障率的例子。并对故障的原因和位置进行了讨论。此外，本文提出了一般可能的程序，故障消除或减轻风险。本文的成果可能是重要的维护，诊断和测试，项目管理和资产管理领域。
In general, there are many types of electrical rotating machines and transformers within various classes of power range and duty cycles. These machines are operated under either industrial or civil conditions. It is a matter of fact that every machine can eventually fail and both damage and losses can occur. Therefore it is necessary to evaluate failure rates and their distribution over certain types of electrical machines and their subsystems. This paper presents an analysis based on the publicly available data, summarizes and compares results obtained from the studies which have been carried out in the past years. In this paper, important machines' subsystems in terms of failure rate are identified. The failure rate is presented in examples. The cause and location of the faults are discussed. Furthermore, this paper suggests general possible procedures for failure elimination or mitigation of the risks. Outcomes of this paper may be important in the field of maintenance, diagnostics and testing, project management and asset management.
