Abstract :
A modified version of wideband inductive divider with guarded cable connections has been built for testing the linearity in multiphase generators. The operative frequency is 500 Hz - 50 kHz for voltage up to 10 V, where it can be calibrated with suitable procedures. Simulation with a lumped parameters circuit has shown that the errors both in phase and quadrature are within 3 parts in 106.
