Overview of Low Voltage Transformers

Oil Immersed Three Phase Electrical Power Distribution Transformer 100kva 125KVA 160KVA 200KVA 315KVA 500KVA 20/0.4KV TOROIDAL is critical power equipment that uses the axiom of electromagnetic induction to convert AC voltage, including voltage, current, impedance conversion, isolation, and stability functions. It usually consists of three parts: primary coil, secondary coil, and iron core (or magnetic core). Low-voltage transformers are widely used in power systems for voltage regulation, impedance matching, and safety isolation. It is also commonly used in various electronic devices and circuits, such as audio devices, TV receivers, computer power supplies, etc., to achieve functions such as voltage, current, and impedance conversion. In addition, low-voltage transformers also play an essential role in safety, preventing excessive recent or circuit failures from posing a threat to equipment or personal safety and protecting equipment from harmful effects such as sudden power changes and surge currnts.
