SECOND DAY ALSO INCLUDES A LABORATORY PART WHERE THE PARTICIPANTS ARE TAUGHT HOW TO PERFORM AN ELECTRICAL
GROUNDING AND POWER QUALITY SITE SURVEY.
HOW TO MEASURE: GROUND RESISTANCE AND RESISTIVITY, POWER QUALITY PARAMETERS SUCH AS:
VOLTAJE, CURRENT, LOAD BALANCE, POWER FACTOR, DISPLACEMENT POWER FACTOR, VOLTAGE, CURRENT AND POWER HARMONICS,
EFFECTIVE POWER (KW), APPARENT POWER (KVA), REACTIVE POWER (KVAR), K FACTOR FOR TRANSFORMERS, CREST FACTOR, ETC,
IN ORDER TO DIAGNOSE AND SOLVE MOST COMMON PROBLEMS.
Earn Continuing Education Unit (CEU) Credits
Successful completion of this course qualifies participants to receive a certificate of course completion with
indicated CEUs. CEUs are granted by either "North Idaho College", "Gonzaga University", "IEEE" or the Engineering Institute of Canada. One CEU is equivalent to 10 professional development hours of instruction.
The following course earns 1.4 CEUs.
It has been determined that over 70 per cent of all electrical problems in industrial, commercial and institutional
power systems are due to poor grounding and wiring errors. Without proper grounding, sensitive electronic equipment
is subjected to destruction of data, erratic equipment operation, and catastrophic damage.
grounding seminar will give participants a comprehensive understanding of practical applications of proper
grounding and wiring practices.
Increase Your Knowledge
· Focus on specific electrical grounding problems and consequences relating to fires, safety of personnel, and damage to equipment
· Participate in discussion of electrical grounding problems and how to overcome or avoid them
· Gain a firm foundation of knowledge for your next project involving electrical grounding
· Develop your knowledge of theory and practice
· The requirements of the National Electrical, CEC in Canada and NOM 001 in Mexico.
· Specific grounding problems, installations and code requirements
· Testing procedures for residential, industrial, commercial and institutional electric power grounding systems
· Practical solutions to grounding problems
After Attending, You Will
· Work more safely and efficiently
· Have a better understanding of Article 250 in the 2005 N.E.C., Rule 10 of the CEC and IEEE Guidelines
· Be more aware of the benefits of good grounding systems
· Be better prepared to design your next grounding system
Who Should Attend
This electrical grounding course is a must for electrical engineers, design engineers, electrical
engineering managers, project managers, power quality specialists, maintenance managers, consultants and technologists
responsible for the design, construction, installation, inspection, operation, or maintenance of electrical systems,
designers, contractors, and electrical technicians, inspectors, safety personnel and other employees responsible for
the operation and maintenance of electrical grounding systems in a commercial, industrial, institutional or utility
Effects of Poor Grounding
Without good grounding, sensitive electronic equipment is subjected to destruction of data, erratic equipment operation,
and catastrophic damage.
Inductive effects of lighting including transients, wiring errors, and code violations cause damages estimated at
about $20 billion dollars in the US and Canada each year.
Loss of sales, Loss of production, Loss of work in process.
The knowledge acquired in this course will enable the participant to apply correct electrical installation procedures
(CEC/NEC), effective cabling and state of the art technologies available for the protection of equipment and circuits.
Code violation poses the greatest hazards to human life.
Sometimes a system shut-down can cause a telecommunications company thousands of dollars per hour. To a petrochemical
company, an unplanned shut down can cost millions of dollars.
With the practical application of the Electrical Code (CEC) and electrical grounding practices, which minimizes errors and loss of equipment, the cost of the course will be
amortized many times over.
Other considerations are Warranties and Guarantees. For insurance validation, these warranties/guarantees are based
on compliance with the Electrical Code (learned in this course).
