Current Transformer

Sort  

Current transformer is an instrument that converts a large primary current into a small secondary current based on the principle of electromagnetic induction to measure it. There are many types of current transformers: residual current transformers, open type transformers, closed type transformers, AC and DC current transformers, which can be used in different locations and different needs. 

The internal materials include:Iron core silicon steel sheet: suitable for iron core materials in current transformers.Ferrite: a magnetic core material suitable for current transformers.Nickel hydride: mainly used in high-precision current transformers.The exterior is insulated and flame-retardant, which is non flammable in the event of an open fire. It is insulated to prevent electrification and protect the circuit.
