A Current Transformer (CT) is an instrument transformer designed to produce a secondary current directly proportional to the current flowing through its primary, safely stepping down high AC currents from thousands of amperes to a standard output of 1A or 5A for accurate measurement and monitoring. Unlike voltage transformers, the CT's primary winding is connected in series with the current-carrying conductor, making it a non-invasive and reliable solution for measuring motor load without interrupting the circuit. Available in three configurations - wound, toroidal, and bar-type, Load Controls' current transformers work in conjunction with our full range of power sensors and load controls, providing the accurate current input signal needed for true power measurement across all industrial motor applications.
