Its main function is to change the number of effective turns on the primary winding (usually the high-voltage side) by switching the winding taps, thereby adjusting the transformer\u2019s turns ratio and keeping the secondary voltage close to its rated value.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Applications:<\/strong><strong><\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">On-load tap changers: Widely used in urban power grids, industrial load centers, and transmission substations where voltage quality is important, they can achieve a voltage adjustment range of \u00b115% with a switching time of less than 200ms.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Off-load tap changers: Mostly used in rural distribution transformers and for seasonal voltage adjustments where voltage changes are infrequent.Smart grids: Modern on-load tap changers can work with automatic voltage regulators (AVRs) to achieve adaptive voltage adjustment.<\/p>","protected":false},"excerpt":{"rendered":"<p>Tap changer&nbsp;is a key device in power systems used to adjust the transformer\u2019s output voltage.
