Voltage Transformer

About Voltage Transformer

The voltage transformer is typically a step-down transformer that is used to reduce the high voltage levels in a power system to a lower, measurable level. The transformer consists of a primary winding and a secondary winding, wound around a common magnetic core. The primary winding is connected to the high voltage side of the power system, while the secondary winding is connected to the measuring or monitoring equipment.The voltage transformer works on the principle of electromagnetic induction. When a high voltage is applied to the primary winding, it produces a magnetic field that induces a lower voltage in the secondary winding. The ratio of the number of turns in the primary and secondary windings determines the voltage transformation ratio.Voltage Transformers are used for a variety of applications, such as measuring the voltage of power lines, monitoring the performance of transformers and circuit breakers, and providing input signals to protective relays. They are designed to be accurate, reliable, and provide electrical isolation between the high voltage side and the low voltage side of the power system.
