SAFETY ELECTRICAL GROUNDING

Ref No: 2015071

INTRODUCTION
System grounding has been used since electrical power Systems began. However, many utilities and industrial plants have used system grounding methods differently. The problem of whether a system neutral should be earthed and how is should be earthed, has many times been misunderstood completely. Therefore grounding of many systems has been based upon past experience rather than engineering analysis.
Today, maintaining a safe and healthy work environment is extremely important. OSHA has become increasingly aggressive in establishing and enforcing safety and health regulations. Employees are much more concerned with their own safety and health on the job. Workers' Compensation and healthcare costs keep growing. And the drive toward achieving more productivity continues. Power plant Safety is the key to dealing with all of these issues. 
This course provides applicable information for grounding, such as definitions, reasons for having a system grounding, equipment grounding, the most desirable grounding method, and so on, and how to measure grounding resistance in order to maintain the grounding system.
Utilities, Industrial and commercial sectors need this course, which studies: the influence of grounding system on performance, protection, security and reliability of electrical networks, and implementation of power plant safety. 
Proper grounding is of course essential for safety in electrical systems of industrial and commercial facilities. In addition, well-grounded systems are required to insure power-quality and reliability as well.  So, are you spending thousands of dollars to repair damage to your sensitive electronic equipment due to lightning strikes or power surges? Is your facility plagued by mysterious electrical problems? Are you designing new facilities? Are you interested in reducing risks to employees? Is your facility interested in power plant safety program?
Please join us for a short course that addresses how to successfully design implement and test  electrical grounding system, and fully implementation of safety program.
