MEGGER TDM45 HIGH POWER TEST AND DIAGNOSIS COMBINATION FOR MV CABLES

TDM 45 series is a revolutionary breakthrough in testing and diagnosis of MV cables. The patented concept addresses the utilities increasing need for flexibility in use of test and measuring equipment based on the type of application.

The modular concept allows the engineer to individually set-up the unit based on the type of job that needs to be executed. If e.g. withstand testing on short cable lengths need to be performed then only one module is needed. When part of the task is also to perform a partial discharge diagnosis then an additional module is needed.
