Which device is not typically found in a Static Voltage Compensator?

A Static Voltage Compensator (SVC) is primarily used for reactive power compensation in transmission systems to enhance the stability and efficiency of the electrical grid. The key components of an SVC include reactors and capacitors that work together to manage voltage levels by absorbing or supplying reactive power.

Reactors, which are inductive devices, are utilized to absorb reactive power, while capacitors provide reactive power support. Voltage controllers are essential for managing the output of these reactive devices to ensure the desired voltage levels are maintained.

Transformers, on the other hand, are not a standard component of a Static Voltage Compensator. While transformers are crucial in power systems for stepping voltage levels up or down and ensuring efficient power distribution, they do not have a direct role in the reactive power compensation function of SVCs.

Thus, recognizing that transformers are not inherently part of the SVC structure highlights why this choice is the correct answer. Instead, SVCs focus on dynamic reactive power management, which is effectively accomplished through the use of reactors, capacitors, and voltage controllers.
