MEDIUM VOLTAGE POWER TRANSMISSION LINE ALTERNATIVE

摘要

The invention is an electrical power system for powering quasi-remote loads wherein local electric utility power is stepped up in voltage and transmitted to a remote battery bank via a low cost, two-conductor, direct burial cable. The system is configured such that current in is this cable is relatively low and constant. The battery bank is used to buffer the low power feed from the electric utility source and the high power, high crest factor remote loads. An inverter, like the type used with off-grid solar power systems, converts the DC battery power to AC power to supply the remote loads.
