It seems like there might be some confusion in your question. A reactor is not typically a part of a transformer system; however, I can explain the roles of both components for clarity:
Transformer:
A transformer is an electrical device that is used to transfer electrical energy between two or more circuits through electromagnetic induction. It consists of two or more coils of wire (known as windings) that are wound around a common core. Transformers are primarily used to step up or step down the voltage levels of alternating current (AC) electrical power. They play a crucial role in transmitting electricity efficiently over long distances, changing voltage levels to match the requirements of different devices, and providing electrical isolation between circuits.
Reactor:
A reactor, in the context of electrical engineering, refers to a coil of wire that is designed to introduce impedance or resistance into an electrical circuit. Reactors are used to limit the flow of current, mitigate power quality issues, and control the rate of change of current in various applications. There are two main types of reactors:
Inductors: These are passive electrical components that resist changes in current. They are commonly used to filter out high-frequency noise or harmonics from electrical circuits.
Iron-Core Reactors: These reactors use a magnetic core made of iron or other magnetic materials to increase their inductance. They are often used in power systems to limit short-circuit currents, dampen voltage spikes, and control power flow.
In summary, transformers are used for voltage transformation and energy transfer in electrical systems, while reactors are used to introduce impedance, control current flow, and manage power quality. It's important to note that while both transformers and reactors are components in electrical systems, they serve distinct functions and are not typically directly related within a single system.
