IG-300 – Fundamentals of Voltage Quality Analysis

IG-300 Course

iGround – What Sets Our Training Apart (PDF)

The IG – 300 brings site analysis full-circle by addressing issues that are related to the transient and steady state voltage quality disturbances that impact sites on a daily basis. The course begins by exploring the important electrical and voltage quality principles that are necessary to understand not only WHAT to look for but WHY and HOW we look for them. The student is guided through an electrical distribution system; from the electrical utility’s generator right up to the end-user’s outlet box to help understand how electrical disturbances are generated externally, and internally, to the site. The students will learn about the power line monitors that are typically used for capturing disturbances. They’ll learn the how to program the power quality monitors and become familiar with the instrumentation thresholds, the benefits, the drawbacks, and the relatively unknown capture characteristics.The IG – 300 is a must for designers and quality assurance personnel who work in diverse electrical and electronic equipment environments.
