Abstract
An electronically aided multistage technique is applied to a hand-held openable-core clamp-on current transformer which enables accurate low current measurements to be made over a aide dynamic and frequency ran ge of operation, for use in conjunction with highly accurate active/re active power and energy meters, and harmonic power analyzers, The clam p-on current transformer can be used to measure currents in the range from 1 A to 200 A, at frequencies between 50 Hz ad 5 kHz, with ratio e rrors of less than 50 x 10(-6) in both magnitude and phase.
