Set up wideband current measurement system with wideband current source and wideband standard voltmeter (such as TH2000 vector voltage analyzer), measure wideband current signal, and calibrate wideband current source and wideband ammeter, etc.

Set up wideband power/energy precision measurement system with wideband I/V conversion standard (such as TH0150 wideband voltage divider) and TH0200 vector voltage analyzer, measure wideband power/energy signal, calibrate wideband power source, wideband power meter, power analyzer and other equipment.

Set up a wideband transformer/sensor measurement system with a wideband constant-current source and a wideband sensor tester (such as TH2000 vector voltage analyzer) to calibrate the tested transformer or sensor with nominal current ≤ 100 A.

For the calibration of transformer/sensor whose nominal current is greater than 100 A, TH0400 is used as the secondary signal I/V converter of the standard and equipment under inspection, and a wideband constant current source and wideband sensor tester (such as TH2000 vector voltage analyzer) are used to build a wideband transformer/sensor measurement system.

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 × [1-(current measurement/nominal current value)^2]

Note [3]: The measured value of AC current should be calculated according to the following formula, and the unit of the difference between AC and DC is ppm:

Ac current measurement value =(voltage measurement value/calibration resistance value)*(1+ AC-DC difference /(1 000 000))
