1. Types of transformer

2. This is the most common type of
transformer, widely used in appliances to
convert mains voltage to low voltage to
power electronics

3. 1-Widely available in power ratings ranging from mW to MW
2-Insulated lamination minimizes eddy current losses
3-Rectangular core

5. 1-Current transformer
A current transformer (CT) is a series
connected measurement device designed to
provide a current in its secondary coil
proportional to the current flowing in its
primary.

6. Voltage transformers (VT) (also called potential
transformers (PT)) are a parallel connected
type of instrument transformer, used for
metering and protection in high-voltage
circuits or phasor phase shift isolation.

7. A pulse transformer is a transformer that is
optimised for transmitting rectangular
electrical pulses

8. There are several types of transformer used in
radio frequency (RF) work. Steel laminations
are not suitable for RF.
