1. A system which supplies Network Line Power (NLP) to any electronic or electromechanical application by means of a Network Line Power Termination (NLPT), the system comprising:

  • a Voltage Enhancer Unit (VEU) which is supplied with power from a central location having an uninterrupted power supply (UPS), wherein the VEU is configured toreceive DC voltage as input from the central location having the UPS, the UPS including a battery and at least one of backup equipment, rectifiers and diesel generators,deliver a positively enhanced voltage on a first copper telephone line,deliver a negatively enhanced voltage on a second copper telephone line, wherein the first and second copper lines form a twisted pair,provide continuous power, under fault free conditions, to one or more NLPTs,limit the positively and negatively enhanced voltages and a maximum available short circuit output current to values within at least one safety standard, andwherein the VEU is electrically coupled to ground and measuring ground currents associated with the enhanced voltage feeds of its output and further configured to detect a ground current in excess of a given value, and disconnect the enhanced voltage outputs and initiate an alarm upon such detection; and

    a Network Line Power Termination (NLPT) which is fed with DC power over at least one copper telephone line pair by a Voltage Enhancer Unit (VEU).
