Instrument Transformer is a general term for current transformer and voltage transformer. It can turn high voltage into low voltage and large current into small current for measurement or protection systems. Its function is mainly to convert high voltage or high current into standard low voltage (100V) or standard low current (5A or 1A, all refer to the rated value) in proportion, so as to realize the standardization and small size of measuring instruments, protection equipment and automatic control equipment. change. At the same time, the transformer can also be used to isolate high-voltage systems to ensure the safety of personnel and equipment.
Transformers are divided into two categories: voltage transformers and current transformers. Voltage transformers can be used for voltage and power measurement in high-voltage and ultra-high-voltage power systems. Current transformers can be used in the measurement of exchanged current, the measurement of exchanged electrical degrees and the protection of power drag lines.
