S. Avramov et al., AUTOMATIC INDUCTIVE VOLTAGE DIVIDER BRIDGE FOR OPERATION FROM 10 HZ TO 100 KHZ, IEEE transactions on instrumentation and measurement, 42(2), 1993, pp. 131-135
A bridge to calibrate programmable and manual inductive voltage divide
rs is described. The bridge is based on a programmable 30 b binary ind
uctive voltage divider with terminal linearity of +/-0.1 ppm in phase
and +/-2 ppm quadrature at 400 Hz. Measurements of programmable test d
ividers can be automated using software developed to align the bridge
components and perform an automatic balance.
