Transformers, also known as instrument transformers, current transformers and voltage transformers are collectively. High voltage can become a low voltage, high current into a small current for measurement or protection systems. Its main function is to high voltage or high current proportionally converted into standard low voltage (100V) or standard small current (5A or 1A, refer rating), in order to achieve measuring instruments, protective equipment and automatic control equipment standardization, and small technology. Meanwhile transformer can also be used to separate high-voltage systems, in order to ensure the safety of persons and equipment
