The Measurement of Body Currents

Transactions of the American Institute of Electrical Engineers, 1941
IN these days of supersensitive amplifiers and recording apparatus, it is very tempting to define life and death in terms of electrical activity. Whether or not this concept is accurate, we can, on present knowledge liken living tissue to a B-battery and dead tissue to a burned out generator. The function of living tissue, however, is so closely allied

The measurement of spot-welding current

Electrical Engineering, 1940
CURRENT is an essential factor in the complete specification of spot-welding conditions. Therefore, the need for the measurement of spot-welding currents arises, if optimum conditions determined in experimental laboratories are to be duplicated in production shops. Laboratory methods must be accurate and supplemented by facilities for ready calibration

Fault-Current Measuring Device

Transactions of the American Institute of Electrical Engineers, 1946
IN electric power system operation numerous problems are encountered in analyzing the results of short circuits and in the physical location of the trouble. Some devices now available for analyzing short circuits in a-c circuits are the oscillograph, the annunciator ammeter, and a magnetic link device requiring rectifiers.

The Measurement of Large Varying Currents

Transactions of the American Institute of Electrical Engineers, 1946
IN OSCILLOGRAPHIC STUDIES where it is necessary to measure current in the range of from 5 to 100 kiloamperes, one must often resort to the use of shunts ...
