10 Different Types of Transformers

Power Transformer: These are typically large transformers used in power generation and transmission to step up or step down voltage levels.

Instrument Transformer (Potential Transformer - PT) / Voltage Transformer (VT): Used to measure high voltage by producing a proportional lower voltage for metering and protection devices.

Autotransformer: A transformer with only one winding, where part of the winding is common to both the primary and secondary circuits. They are smaller and lighter than two-winding transformers for the same VA rating but do not provide electrical isolation.

Isolation Transformer: Designed to provide galvanic isolation between the primary and secondary circuits, preventing direct current flow and providing safety from electrical shock. They typically have a 1:1 turns ratio.

Toroidal Transformer: These transformers use a toroidal (doughnut-shaped) core, which offers advantages like lower magnetic leakage and higher efficiency compared to traditional laminated core transformers.
