A shunt assembly
is a device that is used to measure the flow of electrical current in a power system. It typically consists of a shunt resistor and a set of terminals that allow it to be connected to the power system.
The shunt resistor is the key component of a shunt assembly, as it is responsible for diverting a portion of the current flow through the shunt and creating a secondary circuit. This secondary circuit is used to measure the current flow, and the voltage drop across the shunt resistor is proportional to the current flow.
The terminals of a shunt assembly are typically designed to provide a secure and reliable connection to the power system, allowing the current to flow through the shunt and be measured accurately. In some cases, the shunt assembly may also include a current transformer, which is used to measure high-current applications.
Shunt assemblies are used in a variety of applications, including energy metering, voltage monitoring, load testing, and fault detection. They are designed to be compact and rugged, making them suitable for use in harsh industrial environments. Additionally, shunt assemblies are often designed to be field-installable, allowing them to be easily added to an existing power system without the need for extensive modifications.
