Product Description

TH0490 Bisector Current Ratio Standard

1. Summary
TH0490 is a series of bisector current ratio standard, which can divide the input wideband current into two equal parts before outputting. The ratio error and phase displacement of the two currents are very small.

2. Feature

1. Nominal Input Current: 2 A / 20 A
2. Frequency Range: 45 Hz ~ 5 kHz (TH0490-5kHz);  5 kHz ~ 100 kHz(TH0490-100kHz)
3. Typical Value of Amplitude Error: better than 10 ppm
4. Typical Value of Phase Angle Error: better than20 μrad

 

3. Application

1. Calibrating the AC/DC difference and phase displacement of a precision coaxial shunt.
2. Calibrate ratio error and phase displacement of medium frequency current sensor/transformer.
