Which equipment is generally associated with OLTC operations?

The correct answer is transformers because On-Load Tap Changers (OLTC) are devices specifically designed to adjust the voltage ratios in transformers while the transformer is under load. OLTCs facilitate voltage regulation by changing the number of turns in the transformer winding, which directly impacts the voltage output without interrupting the power supply.

Transformers are integral to electrical systems, as they play a key role in achieving efficient transmission and distribution of electrical energy. The operation of an OLTC is essential for maintaining system stability and optimizing the performance of transformers, especially in scenarios where load conditions fluctuate.

Capacitors, circuit breakers, and inductors do not typically perform the function associated with OLTC operations. Capacitors may be involved in power factor correction, while circuit breakers are protective devices that interrupt current flow during fault conditions. Inductors are used in various applications for controlling current but do not directly interact with the voltage regulation aspects typically managed by OLTCs in transformers.
