If tap changers are on auto and the harmonics are filtered out, what would happen if the tap changers are switched to manual i.e. harmonics/noise

Tap changers in parallel transformers are used to regulate the voltage levels in power systems. They allow for adjustments to be made to the transformer's turns ratio, which in turn adjusts the output voltage. This helps to maintain a stable voltage level and prevent overloading of the system.
Tap changers in parallel transformers have multiple tap positions that can be manually or automatically adjusted. When the tap position is changed, the turns ratio of the transformer is altered, which changes the output voltage. This allows for fine-tuning of the voltage levels to meet the required load demand.
The two main types of tap changers in parallel transformers are on-load tap changers (OLTCs) and off-circuit tap changers (OCTCs). OLTCs are used for continuous voltage regulation, while OCTCs are used for infrequent adjustments. Other types include resistive tap changers, electronic tap changers, and vacuum tap changers.
Tap changers in parallel transformers offer several benefits, including improved voltage regulation, increased flexibility in managing load demands, and reduced power losses. They also help to extend the lifespan of the transformer by preventing overloading and overheating.
Some common issues with tap changers in parallel transformers include mechanical failures, insulation breakdown, and arcing. Mechanical failures can occur due to wear and tear over time, while insulation breakdown and arcing can result from poor maintenance or high voltage spikes. Regular maintenance and monitoring can help prevent these issues.
