1. Summary of TH0420 Reference Coaxial Current Shunt
TH0420 is a set of precision coaxial shunts with ultra-low power coefficients. Each set includes 12 different current range specifications, capable of converting nominal currents from 0.1 A to 500 A into nominal voltage outputs of 1 V or 0.5 V.
TH0420 features an ultra-low power coefficient—for example, the power coefficient of the TH0420-100A does not exceed 10 ppm even when operating at 100 W, making it highly suitable for fast measurements of a wide range of AC and DC currents.
2. Features of TH0420 Reference Coaxial Current Shunt
Typical Annual Drift: 5 ppm; Maximum Annual Drift: 16 ppm
Ultra-low Power Coefficient
Extremely Low Self-heating Power Coefficient and Temperature Coefficient
High Current Carrying Capacity
Capable of Withstanding Instantaneous Current Surges

Set up a wideband transformer/sensor measurement system with wideband constant-current source and wideband sensor tester (such as TH2000 vector voltage analyzer) to calibrate the tested transformer or sensor with nominal current ≤ 500 A.
☆ Build Wideband Transformer/Sensor Calibration System
For the calibration of transformer/sensor whose nominal current is greater than 500 A, TH0420 is used as the standard and the secondary signal I/V converter of the equipment under inspection, and a wideband transformer/sensor measurement system is established with a wideband constant current source and a wideband sensor tester (such as TH2000 vector voltage analyzer).

Note [1]: The initial deviation is the maximum offset of the resistance under DC condition, usually the manufacturer's guaranteed value; Higher precision can be customized according to user requirements, such as 20 μΩ/Ω.
Note [2]: When the coaxial shunt is used to measure DCI, the resistance's own heat will lead to the change of resistance value under different input currents, thus introducing the error. The calculation formula is as follows:
γ= power coefficient x [1-(current measurement/nominal current value)^2]
