摘　　要：公用电力系统需要降低与其设备安装相关的运行和维护成本。降低成本的主要方法就是使用设备在线监测，并且要将基于时间的对变压器维护转变成基于工况的维护。由于监测系统的不断发展，维护和运行人员可以将其工作集中在其他更具有附加值的任务上。除此之外，由于电力市场管制的不断放开，公用电力系统将继续面临更加严峻的挑战。增加设备的负荷，降低维护费用以及延缓投资都是降低使用寿命成本的目的。这些措施同样也可能会造成较高的故障率，同时还会增加发生主要故障的风险。所以，本文的意图就是要在保证一定质量的电能供应同时尽量降低设备维护的成本费用（寿命管理）。Utilities need to reduce costs associated to operation and maintenance of installed equipment. Main ways to achieve this cost reduction are the use of on-line condition monitoring, and a shift from time-based to condition-based maintenance. Thanks to the evolution of monitoring systems, maintenance and operation people can concentrate their activity on other tasks with high added value. Besides these utilities will continue to be faced with daunting challenges due to a deregulated energy market. Increasing loading of equipment, decreasing maintenance expenditures and postponement of investments are goals to reduce life cycle costs. These measures but also can result in higher failure rates and increasing risk of major failures. So the objective is to secure a given quality of supply of electrical energy with minimized cost expenditures for services （life management）.
