The present invention refers to a system for remotely operating and monitoring the integrity of HV/MV/LV (High Voltage/Medium Voltage/Low Voltage), mono phasic or three- phase, power cables, regardless of the cable being under tension, wherein the protection against theft of power cables is one of several advantageous uses. The present invention is based on the principle of two-way communication between two modules, installed one on each end of the cable being operated and/or monitored, using the cable itself to communicate and is characterized by a communication Master module (4) installed upstream to the infrastructure, Slave modules (12), installed at each end located downstream, and bypass modules (9) to pass through circuit breakers. The system is based on determining the cable cutout (alarm condition sent via GSM/GPRS) when the communication between Master and Slave modules is interrupted. The present invention is applicable in the power cable industry and every other industry depending on power cables integrity.
