1. Summary
TH0500 Precision Current Transformers based on the principle of the current comparator, it can produce an output current or voltage that varies directly with the input current from 0.1A to 20 kA. By the connection of a reference shunt burden on the output terminal when outputting an current or directly measuring the voltage when outputting an voltage the primary current can be deduced from the measured voltage .

3.1 Application of type I/V TH0500
☆ Establish current precision measurement system |
|
• Form a current measurement system withTH0500, precision voltmeter and high stability current source. • Implement the measurement of a large current, or provide a DC / AC current signal |
☆ Calibrate High Current Source / meter |
|
• Another typical application of the type I / V transform is paired with a precision voltmeter to calibrate the AC high current standard source / meter. |
☆ Calibrate I/V conversion standards |
|
• Using the I/V type TH0500, you can calibrate the DC shunt, current transducer and other I/ V transform devices in the following two methods. • Calibration by difference method：The selected TH0500 is in the same proportion as the tested I/V, and a micro voltmeter such as a nanovoltmeter is used for calibration • Calibration by voltage ratio method：The selected TH0500 is not proportional to the tested I / V and is calibrated using a voltage ratio measurement device.(Note: For the calibration of type I /I conversion standard such as current comparator and DC current transformer, type I/ I TH0500 is recommended as the standard; the secondary series standard resistance being tested I / I is also used as described in the method above figure.） |
3.2 Application of Type I/I TH0500
☆ Calibrate I/I conversion standards |
|
• I/I type TH0500 can be used to calibrate DC current comparator, current transformer and other I/I conversion equipment according to the following two methods. • Calibration by difference method: the selected TH0500 is in the same proportion as the tested I/I μA micro ammeter for calibration. • Calibration by current ratio method: TH0500 selected is not in the same proportion as the tested I/I, and the current ratio measuring device is used for calibration |
☆ Establish high voltage and high current power/electric energy precision measurement system |
|
• TH0500 can be used with high-voltage V/V conversion equipment (typically TH0170 precision DC voltage divider) and standard power/energy meter (typically TD1310 AC/DC standard meter) to form a high-voltage high current power/energy precision measurement system. • It is used to measure the output power of high-power power supply, the efficiency of conversion equipment, calibrate high-power power source, power meter and other equipment |
