Provided is a system for directly sensing, measuring, or monitoring the temperature of an electrical conductor () of a power cable (). A temperature sensitive capacitor (C) is disposed in direct thermal contact with the electrical conductor (). The temperature sensitive capacitor (C) includes a dielectric material that has a dielectric constant variable with the temperature of the electrical conductor (). The temperature of the electrical conductor () can be sensed, measured, or monitored by measuring the capacitance of the temperature sensitive capacitor (C).

Capacitive temperature sensing for electrical conductor

A terminal connection device comprises a contiguous body disposed onto an inner conductor. The inner conductor includes a first end mateable with a power cable connector and a second end. The body comprises a multilayer structure having an inner conductive or semiconductive layer disposed over at least a portion of the power cable connector, an insulating layer and an outer conductive or semiconductive layer. The body surrounds the first end of the inner conductor and extending towards the second end of the inner conductor. The body can also include an electrically isolated section of conductive or semiconductive material. The terminal connection device can be a fully integrated structure, having a pre-installed connection interface, or the terminal connection device can be configured as an adapter which can be mounted in the field to a connection interface.
