Haiyan Weijia Electrical Technology Co., Ltd.

A Manganin Copper Alloy Watt-hour Meter Shunt Resistor is a type of electrical device that is used to measure the amount of electrical energy used by a load. It is typically used in conjunction with a watt-hour meter, which measures the voltage and current flowing through the load, and calculates the power being consumed.

The shunt resistor is made of a manganin copper alloy, which has a low electrical resistance and high thermal stability. These properties make it suitable for long-term accurate measurements of electrical energy consumption. The shunt is connected in parallel with the load being measured, and a small portion of the current flowing through the load is directed through the shunt, creating a small voltage drop across the resistor. This voltage drop is measured by the watt-hour meter, which calculates the energy consumption based on the current and voltage measurements.

Manganin is a common material choice for watt-hour meter shunt resistors as it has high accuracy and stability over a wide range of temperatures and time. Manganin shunt can have a low resistance and a high current capacity, that way the resistance will not affect the measurement of the current, and it will generate a small voltage drop that can be measured.
