ABSTRACT A system and method is described for expanding the load capacity of a cable system or the like supplied with AC power, without increasing the voltage-drops caused by load currents, by coupling additional loads to such a cable system only during intervals of each half-cycle of the AC power during which instantaneous current values for existing loads are zero or near zero. The existing loads may be cut off from power during such intervals. Also described is an arrangement for locating and replacing defective amplifiers in a cable system, and for controlling gain of and temperature compensating a cable system by interposing or removing amplifier stages.
