Current transformers are very important parts of power grid flow measurement; they can be found in large volumes on all power grids at specific intervals. They are also found mounted on homes and businesses for the purposes of measuring electricity flow; these transformers are fitted with meters that can be easily read by utility workers. Read More…

Current Transformers - Triad MagneticsBecause of the role they play in the measurement and control of the flow of electricity, current transformers are an essential part of all electricity control and access systems. Current transformers are used to obtain the measure of current in an AC power transducer. Current transformers also retain the ability to transform current to a value suitable for measurement or control. These transformers provide isolation and a step-down current output.
Current Transformers - Triad MagneticsAccuracy and cost of current transformers depend on core materials. In a current transformer, the wire to be gauged is placed within the opening of the device and a measure of either alternating voltage or alternating current is produced.
The simplest form of a current transformer consists of two coils of wire, electrically insulated from one another and arranged so that a change in the current in one coil (the primary) will produce a change in voltage in the other (the secondary).
The transformers are designed to provide a current in its secondary, which is accurately proportional to the current flowing in its primary. There are several types of current transformers including protective, measuring, air-gapped, anti-remanence, wideband and linear current transformers as well as differing styles including split core and clamp-on current transformers. As is true with all other electricity control and measuring equipment, extra care must be taken when servicing or inspecting current transformers in order to avoid injury or equipment damage.
