The low-voltage short-circuit method is usually adopted, and the built-in power supply of the instrument applies voltage to the transformer



The transformer capacity characteristic tester is a key device used in the power system to evaluate the core performance of transformers. It can accurately measure the capacity, losses, and other important electrical parameters of transformers under low voltage and small current conditions, and is widely used in scenarios such as installation acceptance, preventive tests, condition-based maintenance, and electricity consumption audits in the power system.
