Product Description

TH 0490   Bisector Current Ratio Standard
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. F eature
  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   1 0 ppm
  4. Typical Value of Phase Angle Error: better than2 0 μrad
 

3. A pplication

  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 . TH0490 Bisector Current Ratio Standard
