High Voltage Electrical Grounding Training

HV Electrical Grounding

This 1-Day High Voltage Electrical Grounding training course teaches students how to design, install and maintain effective high voltage utility and industrial electrical grounding systems.

A properly designed and installed grounding system ensures reliable performance of electrical substations. Fast clearing of faults, made possible by good grounding, improves the overall safety and reliability of an electrical system.

This one-day 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.
