Measuring resistance is an important part of maintaining high-voltage breakers and isolators (disconnecting switches).
Measuring resistance is an important part of maintaining high-voltage breakers and isolators (disconnecting switches).
Instruments that measure the resistance of high-current contacts and other transmission elements have been included in Programma's line of products for many years.

MOM 690 supplements our family of microhmmeters. In addition to high current capacity, MOM 690 features microprocessor-based measurement, storage and reporting. The built-in software enables you to carry out an individual test or an entire series of tests and store the results.

With the optional MOM Win software you can also export the test results to a PC for further analysis and reporting. Ranges are set automatically, resistances are measured continually and test results can be frozen at a preset test current. What could be simpler?

After testing a breaker with a CT mounted in its current circuit, e.g. dead tank and GIS breakers, it is recommended that the CT is demagnetized. This troublesome task can be accomplished quickly and easily thanks to the MOM 690's AC output. The AC output can also be used as a general multi-purpose current source in different applications.
