Precision Three-Stage 1000 V/50 Hz Inductive Voltage Divider

摘要

A separately excited three-stage inductive voltage divider (IVD) has been designed for voltages up to 1000 V at frequencies from 50 Hz to 1000 Hz. The IVD provides output to input voltage ratios of 0.001 to 0.01 with in-phase and quadrature uncertainty of the ratio better than 1×10~(-6).
