Training course length is customizable based on your needs.

This Power Grounding and Quality course will provide the student with the knowledge and skills that will help in troubleshooting power quality problems, determine the current state of an electrical grounding system, and predict when failures are about to happen. An in- depth review of power system grounding fundamentals as well as a review of common power quality problems will be discussed in detail. Waveforms from power quality meters will be analyzed for distortions. Additionally potential corrective actions for power quality issues will be discussed.
