We show the practical steps and results so you can judge suitability quickly. In this video, we demonstrate the RM-F104 electrical transformer trainer in action, covering key training projects like transformer structure recognition, turns ratio testing, no-load and load testing, and short-circuit testing. You'll see how this modular equipment supports skill development in electrical installation and testing, with clear examples of single-phase and three-phase transformer operations, parameter measurement, and safety features.
