Course Summary This course shows how all of the key elements of grounding systems at compressor, storage, and metering stations function, and emphasizes practical solutions to common problems.
A high integrity grounding system is the single most effective means of assuring quality power distribution with a minimum of interference. This practical, detailed look at grounding covers the earth ground electrode system, lightning protection, a full range of both AC & DC grounding systems, protection of utility grounding systems from cathodic protection currents, data line and instrumentation grounding, and ESD and RFI considerations.
Who Should Attend? This course is designed for the technical professional whose job responsibilities include working with AC and DC systems powering critical equipment.
A prerequisite for attendance is a basic understanding of electrical theory and Ohm's law.
What to Expect The class meets from 8 am to 5 pm. Each student will receive a course manual that includes the figures, tables and graphs discussed during the presentation.
Additional Training Upon request, a second day of hands-on Site Inspection Training for private groups may be added at a discount following this course. Site Inspection Training takes place at a client facility, where students will learn the principles and techniques to identify deficiencies in a site’s electrical, grounding, and protection systems including visual inspection and using various field measurement instruments.
