Abstract
Transducers of the average responding RMS indicating type are disclosed that are particularly useful for monitoring currents and voltages in a power distribution network. The transducer includes transformer, inductively compensated voltage divider, active filter and output amplifier circuits electrically connected to provide a transducer having excellent long term transducer stability so that the transducer requires no calibration, and a highly accurate readout over a wide temperature range.
