Substation Grounding Training Substation Grounding Training

Substation Grounding Training - This 12-Hour live online instructor-led course will discuss how to maintain, test, and inspect a proper grounding system for high voltage transmission and distribution systems and especially the electrical power substation.

Safety remains a primary concern for substation owners, specifically in terms of protecting human life, and ensuring reliable network operation. Both electric utility and industrial substation equipment is protected by comprehensive grounding infrastructures. High voltage electrical grounding systems are subject to weathering, corrosion, damage and general wear. System integrity must be inspected and tested on a regular basis. Substation engineers must accurately assess the condition of grounding systems to ensure they are capable of dissipating additional fault current.

This substation grounding training course covers effective relaying and insulation of equipment; and also the safety of the personnel is the governing criterion through the proper design of substation grounding. This course will discuss how to maintain, test, and inspect a proper grounding system for the electrical power substation.

This substation grounding training course covers the ideas behind effective substation grounding system design and describes test methods and numerical models to characterize soil resistivity into a two layer soil model. Participants learn test methods to measure other important grounding system parameters, such as interconnected grounding impedance, neutral and over head ground wire current splits. Then, functional requirements of temporary working grounds are discussed followed by their installation configuration, maintenance and testing.

This course will provide the basic principles of grounding a power supply network to ensure safety of personnel and equipment. Understanding these principles will provide the correct tools to design a grounding system applicable to utility networks and industrial plant distribution. This course covers the basic procedures in working safely on medium and high voltage systems.

This Substation Grounding course will deal with all of these important issues.
