What potential safety concern must be addressed when grounding in a transformer system?

The potential safety concern that must be addressed when grounding in a transformer system is the risk of electrical shock. Grounding plays a crucial role in ensuring safety by providing a low-resistance path for fault currents to flow safely to the earth. This protects personnel from electrical shock by ensuring that hazardous voltages do not build up on equipment or exposed parts.

When a transformer system is properly grounded, it helps prevent electric shock incidents that can occur if a fault causes a conductor to become energized. Without proper grounding, individuals working near the system might accidentally come into contact with live components, increasing the risk of serious injury or fatality due to electrical shock.

Other concerns like overheating of transformers, voltage drop, and equipment wear and tear are more about the performance and longevity of the system rather than immediate safety hazards. While they are important in the overall operation of transformer systems, they do not directly address the immediate danger posed to personnel.
