The Calibration of Current Transformers by Means of Mutual Inductances [PDF]
Transactions of the American Institute of Electrical Engineers, 1915 Reasons are given for the selection of mutual inductances as a means for calibrating current transformers, the most important of which is the wide use to which they may be put besides the calibration of current transformers. The design and manufacture of the apparatus are described, reasons being given for the choice of the form of the secondary coil ...
