A cable assembly includes a cable having a first end and a second end. The cable has an electric conductor and a cooling conduit, each of which extends from the first end to the second end. The cooling conduit is adapted to convey a fluid that cools the electric conductor. The cable assembly includes a leak detection module to detect a leak of the fluid from the cooling conduit. The leak detection module includes a power source to generate an input voltage signal which is applied at a first node contact with the fluid. The leak detection module includes a controller to monitor an output voltage signal at the first node and to detect a leak of the fluid from the cooling conduit based on the output voltage signal.
