A transformer with many secondary coils is typically used for power distribution and voltage regulation in electrical systems. Each secondary coil can be connected to different circuits or devices, allowing the transformer to provide multiple output voltages simultaneously. This type of transformer is commonly used in industrial applications, power plants, and electrical substations to efficiently distribute electricity to various loads.

Isolation Transformers:
- Multiple secondary coils provide varying isolation levels between the primary and different secondary circuits.
Autotransformers with Multiple Taps:
- Secondary coils act as taps on the single primary winding, allowing for variable output voltages and current ratings.
Polyphase Transformers:
- Multiple secondary coils create different phases of AC voltage, such as three-phase transformers used in power distribution systems.
Instrument Transformers:
- Current transformers (CTs) and voltage transformers (VTs) use multiple secondary coils to reduce current or voltage levels for measurement purposes.
Isolation and Filtering:
- Isolation transformers provide isolation between different circuits, while multiple secondary coils can be used to provide additional filtering or isolation of specific frequency ranges.
Impedance Matching:
- Multiple secondary coils can be used to match the impedance of different circuits, allowing for efficient power transfer.
Special Applications:
- Variable Impedance Transformers: Use multiple secondary coils with movable cores to adjust the impedance of the output.
- Magnetic Amplifiers: Employ multiple secondary coils to control the saturation of a magnetic core, resulting in voltage or current amplification.
- Resonant Transformers: Use multiple secondary coils tuned to specific resonant frequencies for applications such as RF power amplifiers and inverters.
- Multiple secondary coils provide varying isolation levels between the primary and different secondary circuits.
