What are the common applications of toroidal transformers？

Toroidal transformer is a special kind of transformer, which is mainly used in the following fields:

1.Power system: Annular transformer is usually used in the protection and measurement devices in power system, such as in the distribution system, to measure current and voltage, and to provide isolation and protection functions.

2.Communication systems: toroidal transformers are also commonly used in communication systems, such as in digital lines, to provide isolation and matching impedance, suppression of interference and noise, etc.

3.Audio systems: Toroidal transformers are commonly used in hi-fi audio systems, such as in audio amplifiers and speakers, to provide isolation and matching impedance, and to suppress interference and noise, among other things.

4.Measurement and detection: toroidal transformers can also be used in a variety of measurement and detection applications, such as flux meters, energy meters, medical equipment, etc., to provide accurate current and voltage signals.

In general, toroidal transformers have a wide range of applications, mainly used to provide isolation, impedance matching, interference and noise suppression and other functions.
