Why does substation grounding require extra training?

Substation grounding requires extra training because the risks associated with grounding systems are significant, and qualified electrical workers may not be familiar with the specific equipment and procedures used in substations. Grounding in a substation context involves understanding complex systems and the potential hazards related to high-voltage equipment, making specialized training crucial. Workers must be trained to identify proper grounding techniques, understand equipment configurations, and handle potential faults to ensure safety and system reliability.

The other options do not hold true in this context. Grounding systems in substations can be extremely dangerous, especially if not properly managed or understood. Additionally, the variety of equipment in substations is extensive, and a general electrical background may not sufficiently cover the specific grounding requirements necessary for safe operations. Therefore, adequate training becomes essential to equip workers with the knowledge required to work safely and effectively in such high-risk environments.
