This article discusses the importance of managing developed electrical preventive maintenance (EPM) programs, challenges resulting from underdeveloped EPM approaches, and methods for implementing and managing these initiatives. Electrical equipment that has not been properly maintained can impact worker safety due to undocumented and unknown conditions. With aging infrastructure and modifications to electrical systems through time, previously calculated short circuit capacities, arc-flash hazards, and device coordination may not reflect the installed electrical system. Performing preventive maintenance on electrical systems at industrial facilities, especially low-voltage systems, can be more difficult during economic downtimes. Justifying the costs associated with maintaining and/or upgrading systems can be challenging.

工业设施中电气设备的管理和维护：提高安全性和省钱的程序

本文讨论了管理已开发的电气预防性维护 (EPM) 计划的重要性、不完善的 EPM 方法带来的挑战以及实施和管理这些计划的方法。由于未记录和未知的情况，未正确维护的电气设备会影响工人的安全。随着基础设施的老化和电气系统的修改，先前计算的短路容量、电弧闪光危险和设备协调可能无法反映已安装的电气系统。在经济停机期间，对工业设施的电气系统（尤其是低压系统）进行预防性维护可能会更加困难。证明与维护和/或升级系统相关的成本可能具有挑战性。
