Working principle:
Transformer is the use of the principle of electromagnetic induction to change the AC voltage, current and transmission of AC power an electrical device, the main components are the primary coil, secondary coil and iron core (core), its main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer) and so on. Transformers can be divided into: power transformers, test transformers, instrument transformers and special purpose transformers.
It is mainly used for power extraction, energy conversion, power measurement, leakage protection, etc. Such as: various types of different levels of current transformers, power transformers, current sensors, etc. used in the power system.

Features and uses:
This type of iron core has superior magnetic properties, high permeability in a weak magnetic field, low saturation magnetic induction and high resistivity. It is mainly used for power transmission, energy conversion, energy measurement, and human Electric protection and other aspects. Such as: various types of current, voltage transformers, safety devices used in power systems, and other examples: input transformers, pulse transformers, magnetic amplifiers, magnetic screens, sensor stepping motors and electronics used in automatic control systems Computer memory components, etc., are widely used.
Hemei Electronics's self-powered current transformers have been applied to power supply, power grid, petrochemical, metallurgy, railroad transportation and urban construction, etc. The domain is gradually expanding to new energy power generation, rail transportation, data centers, new infrastructures and other emerging fields.
