Current Transformer Basics: Understanding Ratio, Polarity ...· Current Transformer Types. There are four typical types of current transformers: window, bushing, bar, and wound.The primary winding can consist merely of the primary current conductor passing once through an aperture in the current transformer core (window- or bar-type), or it may consist of two or more turns wound on the core together with the secondary winding (wound type).

Transformers Supplier Philippines - Meiji Electric· According to the Business Dictionary, a transformer is a device that converts an alternating (A/C) current of a certain voltage to an alternating current of different voltage, without change of frequency, by electromagnetic induction. A 'step up' transformer receives a low voltage and converts into a higher voltage, and a 'step down' transformer does just the reverse.
