TH0500 Precision Current Transformer

1. Summary of TH0500 Precision Current Transformer

The TH0500 is a series of precision current conversion standards that utilize high-precision DC current comparator technology. They convert nominal DC/AC currents ranging from 0.1 A to 20 kA into proportionally smaller voltage or current signals while maintaining a high level of ratio accuracy. By connecting the secondary output to appropriate measuring instruments, a wide variety of measurement applications can be achieved.

2. Features of TH0500 Precision Current Transformer

• Supports two current access modes, through core and direct connected type respectively.

Direct connected type with the input current of 0.1 A…200 A

Through core type with the input current of 500 A…20 kA

• Secondary output signal is optional for current (I / I) or voltage (I/ V)

I/I：Optimum uncertainty of 2ppm

I/V：Optimum uncertainty of 10 ppm

☆ Calibrate I/V conversion standards

TH0500 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.）
