A step-down transformer is an electrical device that reduces high voltage to a lower voltage while maintaining the same frequency. It is commonly used in power distribution systems to lower the voltage for safe and efficient use in homes, businesses, and electronic devices.
- Voltage Reduction: Converts high input voltage to a lower output voltage.
- Two Coils (Windings): There are more turns in the primary coil and fewer in the secondary coil, which results in a voltage decrease.
- Core Material: Typically uses laminated silicon steel cores to reduce energy losses.
- Efficiency: High efficiency (often above 95%) for power transmission.
- Safety: Reduces voltage to safer levels for end-user applications.
- Applications: Used in power adapters, substations, industrial machinery, and electronic chargers.
