In the power system, accurate measurement is the basis for ensuring the stable operation and efficient management of the power grid.

The transformer has the advantages of flexible voltage adjustment, high efficiency, safety and energy saving, strong environmental adaptability, excellent technology and significant application advantages.

In recent years, with the advancement of technology, single coil transformers have received widespread attention in multiple application fields due to their unique design and performance advantages.

In modern power systems, measuring transformers, as one of the core components, bear the important responsibilities of voltage conversion and electrical isolation.

Temperature rise test is the core means to verify the rationality of measuring transformer design and the efficiency of cooling system.

Accurately measuring dynamic magnetic flux changes in measuring transformers is a challenging task, which requires the measurement system to have high precision, high response speed and good anti-interference ability.
