Many utilities have made commitments to establish inspection programs for monitoring the condition of non-EQ cables during their extended operating license period. The reason behind these commitments is simple. Cable integrity is very important to the safe operation of the electrical circuits within a nuclear power plant, especially when you consider that the circuit components will see 40+ years of use .
The approach for using the ECAD tester requires that the circuit under test be logically organized as a set of two-wire configurations. For most circuits, the total number of combinations is manageable so that the time required to move the test lead connections between configurations is not significant. The test lead connection time does, however, become more significant as the number of two-wire configurations increases or if the number of similar circuits to be tested becomes large.
The Nuclear Instrumentation System (NIS) is one the most important instrumentation and control systems in a nuclear power plant . Operators use the outputs of these circuits to ensure that the reactor is operating safely and within the specified limits in all operating modes.
We are in the process of implementing a major overhaul of the CM Technologies website (www.ecadusa.com). As we are making changes, you might encounter some broken links or observe some odd behavior so we apologize in advance.

CM Technologies Corp Successfully Troubleshoots 4 kV Festoon Cable at the APM Terminals’ Facility in Elizabeth, NJ
The Crane Manager at APM Terminals’ Elizabeth, New Jersey facility reported a complete failure of 4 kV festoon cable on Crane #4 in December 2013. The crane was forced to shut down until the problem was resolved, limiting the shipyard’s ability to load and unload boats. A damaged wire causing a short circuit was believed to be the culprit. After three months of downtime spent troubleshooting the problem, CM Technologies was called to track down the fault.
