What is the transformer volt-ampere characteristic tester used to measure?

A transformer is a device that converts voltage or current in proportion. As a connecting element between primary system and secondary system, transformer is very important in power system. Its main function is to convert high voltage or large current into standard low voltage (100V) or standard small current (5A or 1A, both refer to rated value) in proportion, so as to realize the standardization and miniaturization of measuring instruments, protection equipment and automatic control equipment. At the same time, the transformer can also be used to isolate the high voltage system to ensure the safety of personnel and equipment.
