Causes of Transformer Differential Current and Hazards of Transformer Bias CurrentTransformer differential current is caused by factors such as incomplete symmetry of the magnetic circuit or insulation damage. Differential current occurs when the primary and secondary sides of the transformer are grounded or when the load is unbalanced.Firstly, transformer differential current leads to energy waste. Differential current causes additional power loss in the transformer, increasing the load on the
