ترانس ZEMCT303A در واقع یک مبدل جریان 40A به 40mA با نسبت تبدیل 1000 به 1 است و برای محافظت از رله ها، موتورها و سیستم های اندازه گیری کاربرد دارد.
Description:
A current transformer (CT) is a type of transformer that is used to reduce or multiply an alternating current (AC). It produces a current in its secondary which is proportional to the current in its primary. Current transformers, along with voltage or potential transformers, are instrument transformers. Instrument transformers scale the large values of voltage or current to small, standardized values that are easy to handle for measuring instruments and protective relays.
