[0002] Transformers can convert high voltage into low voltage and high current into low current, and are used in measurement or protection systems. Their main function is to proportionally convert high voltage or high current into standard low voltage (100V) or standard low current (5A or 1A, both refer to rated values) in order to achieve standardization and miniaturization of measuring instruments, protection equipment and automatic control equipment. At the same time, transformers can also be used to isolate high-voltage systems to ensure the safety of people and equipment. Transformers usually use outgoing line bars to connect lines.
