What does a transformer do?
Transformers: divided into voltage transformer, current transformer, zero sequence transformer, etc.
Voltage transformers: converts different voltages into a unified value to match the instrument or meter. The secondary voltage is mostly 100V or 220V.
Current transformers: Change different currents into a unified current value to match the instrument or meter. Generally, the secondary current is 5A.
Zero-sequence transformer: It mainly measures the neutral line current. It is a sensitive current transformer. Its secondary current can measure dozens of milliamperes.
Instrument transformer, also known as instrument transformers, is the collective name for current transformers and voltage transformers. It can change high voltage into low voltage and large current into small current for measurement or protection system. Its main function is to proportionally convert high voltage or high current into standard low voltage (100V) or standard small current (5A or 1A, both refer to the rated value), in order to realize the standardization and small size of measuring instruments, protection equipment and automatic control equipment. change. At the same time, transformers can also be used to isolate high-voltage systems to ensure the safety of people and equipment.

People use Current transmitter. Why do people use transmitters, in the chillers the air compressors, the generators and the IoT systems? In systems I see chillers, in commercial buildings air compressors in factories and generators, in data centers. The chillers, the air compressors and the generators all have one thing in common. In short devices… Continue reading Why Current Transmitter Matter in Chiller, Air Compressor, and Generator
