According to our (Global Info Research) latest study, the global On-load Tap Changer (OLTC) market size was valued at US$ 778 million in 2025 and is forecast to a readjusted size of US$ 968 million by 2032 with a CAGR of 3.2% during review period.
The tap changer is the key core component of the transformer, also known as the tap changing device of the transformer winding, that is, the tap changer is set at different parts of the transformer winding, and the number of turns of the transformer winding is changed by changing the position of the tap. voltage adjustment. At the same time, the tap changer is the only load-operating component in the transformer composition.OLTC refers to a voltage regulating device suitable for operating under transformer excitation or load and used to change the tap connection position of transformer windings.In the power grid system, OLTC can be used to adjust the voltage without interruption of power supply, to control the direction of power flow, realize cross-regional long-distance power transmission, and at the same time regulate the voltage of the power supply area caused by the change of load to stabilize the voltage. Grid voltage, improving power quality. In addition to the power grid system, transformers with high energy consumption levels of power equipment, large voltage load changes, and frequent start and stop also need to be equipped with OLTC to improve and stabilize power quality.
