What type of wiring/cabling problems can an ECAD tester identify?

In general, the ECAD technology can identify and locate problems with the conductors in a cable/wire and insulation (dielectric) changes.    The easiest problems to troubleshoot are short-circuited or open-circuited conductors; these conditions influence more one of the tester’s measurements and usually produce a unique TDR signature.

Insulation degradation, such as heat damage, moisture ingress, and low resistance shunts, are also good applications for the ECAD technology.

CM Technologies has also researched and developed specialized measurement techniques to identify subtle forms of circuit degradation, including the changes that occur naturally in common insulation materials.  These techniques could be app

What type of support options are available for owners?

If you own an ECAD tester and need help interpreting a set of test results, CM Technologies offers “second opinion analysis”  to support maintenance decisions.    You can simply email some background information regarding the issue and the database to a support engineer.   The support period can be tailored to coincide with an outage or be made available throughout the year.   CM Technologies’ response can range from a complete engineering report to a simple email, as required by the customer.

Anther option for obtaining support is to have CM Technologies perform the on-site testing using your ECAD tester.  This approach can free up maintenance personnel during outages when resources are scarce.
