The sweep frequency response analysis (SFRA) test is a powerful and sensitive method for assessing the mechanical and electrical integrity of a transformer core/coil assembly. SFRA includes two tests: an open test and a short-circuit test. Both test a complex network of inductances, capacitances, and resistors, and frequently successfully detect the presence of an electrical failure, including a shorted turn. …

In power system protection, time has always been central—from coordinating relay trip times to selecting algorithms and schemes with the fastest trip times for fault clearing. Historically, however, time synchronization was largely an afterthought serving SCADA and event logging. That has changed with today’s digital substations. This article explains how precision time protocol (PTP) based on IEEE Std. 1588 enables …

Most utilities in the United States are required to comply with North American Electric Reliability Corporation (NERC) regulations. Some of these regulations require utilities to develop performance-based, condition-based, or time-based maintenance programs, and the execution of these programs is what opens a window of opportunity for testing companies to offer services oriented to help utilities achieve their maintenance testing needs. …
