Split-core iron core current transformers are electrical devices used to measure high voltage currents. They can convert high currents into low current outputs and ensure that the current information is not lost during output. This type of transformer consists of an iron core and several coils, with the iron core able to induce current onto the coils which is then stepped down through the circuit.

Motor test measurements usually require ammeters to be equipped with multiple shunt units to solve the problem of ensuring the desired measurement accuracy over a larger measurement range. At this point, the rated voltage drop of all shunt used must match that of the ammeter (e.g. 75 mV).
