Mikrosensorik current transformer process

Current Transformers. Current transformers (CT) are devices that are used to transform the current from a high current into a lower current so that the power can then be measured and controlled. The transformers consist of a core, a primary and a secondary winding. When an alternating current flows through the primary winding, a magnetic flux is created which then induces an alternating current in

  • Current Transformer: Definition, Principle, Equivalent

    8 mins readDec 27, 2013The current transformer basically consists of an iron core upon which primary and secondary windings are wound. The primary winding of the transformer is connected in series with the load and carries the actual current flowing to the load, while the secondary winding is connected to a measuring device or a relay.

  • 6 electrical tests for Current Transformers explained

    May 12, 2017Current transformers play an important role in the monitoring and protection of electrical power systems. CTs are instrument transformers used for converting primary current into a reduced secondary current for use with meters, relays, control equipment and other instruments. The importance of instrument transformer tests is often underestimated.

  • The Correct Way to Specify and Install Current Transformers

    Mar 07, 2017To correctly measure current, the CT has to be able to wrap around the entire conductor of the current being measured. Typically, larger amounts of electricity require larger wires, so it’s important to keep window size in mind. What Style Current Transformer Should I Specify? We use three types of current transformers that come in all sizes.
