Claim 11:
12. A cable tray assembly comprising:
a cable tray run having a base portion, opposing side walls extending from the base, and a length, wherein the cable tray run is configured to support one or more electrical cables;
a first leakage detector configured to be disposed at a first longitudinal location of the cable tray run, the first leakage detector including a first magnetic sensor and a first electrical conductor coupled to the first magnetic sensor, wherein in use the first leakage detector is configured to sense magnetic flux generated by current flowing through the one or more electrical cables adjacent the first leakage detector, wherein the first electrical conductor extends around the cable tray run in a direction generally transverse to the length of the cable tray run;
a second leakage detector configured to be disposed at a second longitudinal location of the cable tray run, the second leakage detector including a second magnetic sensor and a second electrical conductor coupled to the second magnetic sensor, wherein in use the second leakage detector is configured to sense magnetic flux generated by current flowing through the one or more electrical cables adjacent the second leakage detector, wherein the second electrical conductor extends around the cable tray run in a direction generally transverse to the length of the cable tray run; and
a central computing device configured to receive: i) a first signal from the first leakage detector indicative of the magnetic flux generated by current flowing through the one or more electrical cables adjacent the first leakage detector, and ii) a second signal from the second leakage detector indicative of the magnetic flux generated by current flowing through the one or more electrical cables adjacent the second leakage detector, wherein the central computing device is configured to compare the first and second signals to determine if there is leakage current from the one or more electrical cables in the cable tray run.
