This self-paced class covers transformer turns ratio, power factor and capacitance (UST/GST), excitation and leakage reactance, SFRA, CT testing, variacs and the transformer test kit, plus a field walkthrough and a composite case study. It has about 45 minutes of lesson content plus video clip activities, two practice activities and a 30-question quiz. It is part of the SubstationU.com Introduction to Electrical Test Equipment series (Level 1 course). Continuing education credit: 0 (none awarded yet).
Read the lesson book, complete the video clip activities and the two practice activities, then pass the 30-question quiz with 80% (24 of 30) or better; you can retake the quiz as many times as you need until you pass. Each of the eight classes is a separate course; the recommended order is Class 1 to Class 8, but you can take them in any order.
