WebFurther, it may lead to transformer core overheating. Power Transformer core earthing limits the flow of Eddy Current on the core. It eventually minimizes the Eddy Current loss too. What can happen if Power Transformer Cores are not grounded? Power Transformers can still operate without core grounding. But it may lead to following issues. WebDuring the line-to-ground faults, grounding transformers provide an easy path to ground faults to limit the fault currents and transient over voltages. Grounding transformers normally carry short-circuit ground current until …
