Ⅲ. Applications

Fixed value shunt is a kind of external shunt which is suitable for measuring DC current under 10kA and directly acting on analog display instrument and used to expand the range of DC current measurement.
It is also can be regarded as a standard resistor for current sampling in a sequential circuit whose sampling voltage can be regarded as an analog signal of the primary current used for measurement.
