What are Shunts?
Shunts are a type of resistor designed to be used as a measuring instrument for low and high levels of voltages. The shunt's accuracy is measured at ¼% of the value rated and for continuous operation, it’s recommended that the shunts used don’t exceed 2/3 the IEEE rated current. If temperatures exceed 80°C on the shunt then resistance may drift and if it goes beyond 140°C, the resistance will be permanently altered. Shunts should typically reach 80% of its operating temperature within the first 2 minutes of operation. Leads are an important part of how Shunts are applied to applications as it isn’t a good idea to mount shunts close to the instrument reading device. It also isn’t recommended to have longer lead lengths, but if necessary additional drops in load must be considered when applying instrument reading devices. When connecting shunts it should also be done on the grounded side of the line.

Application of Ground Straps & Shunts:
Shunts can handle moderate temperature environments and are able to be successfully applied in mining industries, equipment manufacturing and distribution of power, nuclear applications and original equipment manufacturing. Being corrosion resistant shunts are able to handle moderate amounts of handling and be applied in specific hazardous environments.
There are always things to consider when purchasing wire and the same goes for shunts. There are 4 major factors to take into account:
- Ambient- Temperature elevated or high altitudes
- Temperature rise- Normal, limited or fluctuating
- Duty- Continuous, surge or intermittent
- Environment- Open air, grouped, closed, forced air
- Combinations of 1 through 4
Any combination of these factors may exist in specific scenarios. When this occurs it will be a necessity to take all these factors into consideration in order to find the correct rating. Shunts can be placed anywhere a specific current needs to be measured but should be done in a vertical position in order to help with airflow. Newly developed shunt models allow for more than one input so multiple inputs and outputs are able to be measured. Shunts work off of ohm’s law (Voltage (E) = Current (I) x Resistance(R)) to give the most accurate measuring of current flow through a circuit. Typically used as expansion joints that hold together equipment misalignment, the customizable Shunts are able to replace Voltmeter or Multimeter, because of the extremely higher voltages it can handle for extended amounts of time.
