The common test instruments (i.e., Megger, Hi-Pot, Dissolved Gas Analysis, etc.) used to analyze equipment problems are explained in this course. Examples of maintenance test procedures (i.e., batteries, earth resistivity, etc.) are discussed in this class. Safety precautions during maintenance procedures are also discussed; such as PCB handling and Lead Awareness.
This course is part of APT's Electric Power Proficiency Certification Program.
