Current transformers, along with voltage or potential transformers, are instrument transformers, which scale the large values of voltage or current to small, standardized values that are easy to handle for measuring instruments and protective relays. Instrument transformers isolate measurement or protection circuits from the high voltage of the ...
Current transformers used in metering equipment for three-phase 400 ampere electricity supply SF 6 110 kV current transformer TGFM series, Russia. Current transformers (CT) are a series-connected type of instrument transformer. They are designed to present negligible load to the supply being measured and have an accurate current ratio and phase ...
General purpose instrument measures voltage, current and resistance (and sometimes other quantities as well) Network analyzer: Measures network parameters Ohmmeter: Measures the resistance of a component Oscilloscope: Displays waveform of a signal, allows measurement of frequency, timing, peak excursion, offset, ...

A current clamp uses a current transformer with a split core that can be easily wrapped around a conductor in a circuit. This is a common method used in portable current measuring instruments but permanent installations use more economical types of current transformer.
The current value may be directly displayed by an instrument, or converted to digital form for use by a monitoring or control system. Current sensing techniques include shunt resistor, current transformers and Rogowski coils, magnetic-field based transducers and others.
An instrument that measures electric current. amorphous metal transformer A power transformer where the metallic core is made of metals cooled so quickly that they do not form a crystal structure; such transformers can reduce some kinds of energy loss. ampacity The current carrying capacity of a conductor, in the context of electric power ...
