Abstract

Power cable monitoring system comprising one or more transducers distributed along the cable. Each of the transducers is operationally connected to the cable for measurement of operational parameters of the cable, such as temperature, pressure, voltage, current, etc., and provides an output signal in response to actual parameter values. A data cable, such as a coax cable, a twisted a pair cable, an optical fibre cable, etc., positioned adjacent to and extending substantially in parallel is connected to the transducers.
