What hazard is created by using the bracket grounding method?

Using the bracket grounding method can lead to the hazard of circulating currents through induction. This occurs when grounding mechanisms are improperly configured or placed in a manner that allows electromagnetic induction to create unwanted currents. In environments such as substations, where large currents and magnetic fields are present, if the grounding is not appropriate, these induced currents can flow through unintended paths and create unsafe conditions.

Circulating currents can particularly become problematic when they interact with the grounding systems of other equipment, leading to voltage differentials that can affect the operation and safety of electrical systems. Proper grounding techniques are critical in mitigating this risk, ensuring that any fault currents have a safe path to ground without generating inductive effects on nearby equipment. This helps maintain system integrity and minimizes hazards to personnel and equipment alike.
