[0002] Instrument transformers, also known as instrument transformers, are a general term for current transformers and voltage transformers. They 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 convert high voltage or high current into standard low voltage (100V) or standard low current (5A or 1A, both refer to rated values) in proportion, so as to achieve standardization and miniaturization of measuring instruments, protection equipment and automatic control equipment.

[0003] As an important component of the transformer, the connecting piece usually consists of two parts: a copper block and a lead pin. During use, the copper block and the lead pin are usually connected by riveting.
