New concepts in systems for electrical measurement
A. J. Corson, Roger M. Rowell · IEEE Transactions on Communication and Electronics · 1963
A new concept of more flexible instrumentation for power systems is described. A group of individual transducers is used for measuring the usual electrical quantities and temperature, each producing a high-level d-c output suitable for either analog or digital readout. Conventional d-c mechanisms are used in the end devices, eliminating the need for more complex mechanisms. The operating principles, performance characteristics, and circuit diagrams of six commercially available transducers are given.
