Summary
The important information covered in this chapter is summarized below.
Transformer Types Summary
Distribution transformers are generally used in power distribution and
transmission systems.
Power transformers are used in electronic circuits and come in many different
types and applications.
Control transformers are generally used in circuits that require constant voltage
or constant current with a low power or volt-amp rating.
Auto transformers are generally used in low power applications where a variable
voltage is required.
Isolation transformers are normally low power transformers used to isolate noise
from or to ground electronic circuits.
Instrument potential and instrument current transformers are used for operation
of instruments such as ammeters, voltmeters, watt meters, and relays used for
various protective purposes.
