The high pressures required for the economical use of transmission lines necessitates the employment of transformers at each end of the line; namely, step-up transformers at the transmitting end, to raise the voltage delivered by the generators, and step-down transformers, at the receiving end, to lower it for use in the various translating devices.

All agreed that some wire connecting heart and brain had burned out when the cruel "System" threw on a voltage beyond the wire's capacity to transmit.

Revivalism works up the voltage, then makes no use of the currentthe wire is grounded.
