Leak detection in a cable assembly

A cable assembly comprising:

• a cable having a first end and a second end, the cable comprising an electric conductor and a cooling conduit, each of which extends from the first end to the second end, wherein the cooling conduit is adapted to convey a fluid that cools the electric conductor;
• and
• a connector attached to the second end of the cable, wherein the cooling conduit forms a fluid channel around an interior of a handle of the connector and is adapted to cool the connector;
• and
• a leak detection module coupled to the cable and the connector, the leak detection module comprising:
• a power source to generate an input voltage signal wherein the input voltage signal is applied to the fluid at a first node in contact with the fluid;
• and
• a controller configured to monitor an output voltage signal and to detect a leak of the fluid from the cooling conduit based on the output voltage signal.

• and
• a controller configured to monitor an output voltage signal and to characterize a leak of the fluid from the cooling conduit based on the output voltage signal based on a comparison of the monitored output voltage signal with two representative output voltage values, a first representative output voltage value associated with a fluid leak and a second representative output voltage value not associated with a fluid leak.
