High Voltage Grounding Training explains substation grounding systems, grounding grid design, soil resistivity testing, and IEEE 80 safety principles used to control ground potential rise, fault currents, and step and touch voltages in medium- and high-voltage power systems.
This 6-Hour instructor-led High Voltage Grounding Training course will provide the basic principles of grounding a power supply network to ensure the safety of personnel and equipment.
High voltage substations must safely dissipate thousands of amperes of fault current into the earth. Improper grounding design can produce dangerous step and touch voltages, ground potential rise (GPR), and equipment damage.
This course explains how substation grounding systems are designed using IEEE Std 80 engineering methods, including grounding grid design, soil resistivity analysis, fault current distribution, and step- and touch-voltage safety calculations.
Participants learn how grounding grids, ground rods, and bonding conductors are designed to control voltage gradients and protect personnel in medium- and high-voltage substations.
A properly designed and installed grounding system ensures the reliable performance of electrical substations. Fast fault clearing, made possible by good grounding, improves the overall safety and reliability of an electrical system.
Understanding these principles will provide the right tools for designing grounding systems for utility networks and industrial plant distribution. This course covers the basic procedures for working safely on medium and high voltage systems.
This comprehensive course focuses on the latest practices and standards for grounding and bonding in high-voltage systems. Participants will gain a deep understanding of safe grounding methods, conductor sizing, substation grounding design, surge protection, and bonding practices, specifically tailored for utility and industrial applications.
