Technical notes

Application

Shunts are used for indirect detection of high electric currents.

How they work in principle

The current flowing through the shunt shows a voltage drop which can be measured with a measuring device connected in parallel. By connecting the shunt and gauge in parallel it is possible to use voltmeters to measure current or to extend the measurement range of existing electricity meters.
