- Editor's Notes
- drawing "Object of patent regulation of the EMF at the reducing station while that at Central Station is constant-- AA' are tow Motors wound so that a 1/2 speed they give a minium counter electro motor force B are motors which are run from the low tension line-- When the volts are to be increased or diminished on the high line the fields of B are increased or diminished in strength & thus the motor B runs at a higher or lower speed-- Thus causing A to give greater or lesser counter EMF or back pressure Thus if the Central station has a constant of 2500 volts & A a counter pressure of 500 volts, The net will be 2000; if now there is a fall of pressure due to load The strength of the field of B is increased, the speed of A diminished & the back pressure diminishes thus bringing the pressure up to the required amount."
