Power Transmission by Alternating Currents - Editorial

The brief paper by William Stanley. Jr., which we publish elsewhere, gives an interesting view of the alternating current phase of power transmission. It is specially important as bringing to public notice again the very ingenious motor devised by Messrs. Stanley and Kelly, to which reference has several times been made in our columns. One very pretty feature of this machine is the ingenious method for neutralizing lag between field and armature circuits. This question of a practical alternating motor for general use is one of the greatest importance since on the existence of each machine depends the availability of the alternating current in the general transmission of power. In cases where the electromotive force of transmission must be higher than that of utilization, the high efficiency of the alternate current transformer is of no avail unless convenient and efficient motors can be employed in connection with it.
