We know it as a measuring device.But it can act as
protecting device also.
It is basically a step-up transformer.It raises the
voltage thereby reducing the current(as high as 100A or
more) in a circuit so that it can be measured using a std 5A
or 1A ammeter.Primary is the conductor containing the
circuit in which the current is to be measured.
