Transformer Technology Overview

These flashcards cover key concepts and terms related to transformer technology as discussed in the lecture notes.

Double Wound Core Transformer

A transformer that has both a primary and a secondary winding.

Induced EMF

The electromotive force generated in the secondary coil due to the changing magnetic field created by the primary coil.

Turns Ratio

The ratio of the number of turns in the primary coil to the number of turns in the secondary coil, affecting voltage and current.

Eddy Currents

Currents induced in the core of a transformer which can cause heating and power losses.

Back EMF

The voltage that opposes the applied voltage in the primary coil due to self-induction.

Step-up Transformer

A transformer that increases output voltage, having more turns in the secondary coil than in the primary.

Step-down Transformer

A transformer that reduces output voltage, having fewer turns in the secondary coil than in the primary.

Power Transformer

A type of transformer commonly used in power transmission and distribution.

Current Transformer

Used for measuring electric currents, often with high accuracy for metering.

Isolation Transformer

Used to separate circuits for safety purposes, often providing 1:1 isolation.

Shell Type Transformer

A transformer design that is more efficient due to its ability to circulate magnetic flux through two paths.

Core Type Transformer

A transformer design that channels magnetic flux through one path, potentially leading to leakage flux.
