E-Learning – Troubleshooting And Maintenance Electrical

Overview

This plant maintenance training program builds on the troubleshooting electrical control circuits program. The program contains sections to describe how the electrical motor control circuit works as well as how to use the troubleshooting tools. The program evaluates the time and money spent to solve the fault and records all the steps performed to solve the fault.
