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

In power systems, transformers, as core equipment, are critical to the safe operation of the entire grid. However, due to various reasons, transformers are often exposed to multiple threats. In such cases, the importance of grounding resistor cabinets becomes evident, as they provide indispensable protection for transformers.Firstly, grounding resistor cabinets can effectively protect transformers from lightning strikes. The instantaneous high voltage caused by lightning can severely damage tran

1.Linear Regulators vs. Switching RegulatorsA linear regulator requires an input voltage higher than its output voltage. It handles the difference between input and output voltages—known as the dropout voltage—by varying the impedance of its internal regulating element (such as a transistor).Think of a linear regulator as a precise “voltage control expert.” When faced with excessive input voltage, it decisively “acts” by “cutting off” the portion exceeding the desired output level, ensuring the
