This article describes the different testing challenges per asset and shows the possibility how to achieve a higher efficiency using an optimised testing approach. - Christian Enk, Martin Pfanner

Commissioning tests and periodic on-site maintenance checks are essential for the safe and outage-free operation of power transformers and substations. A combination of routine...

Temperature monitoring using advanced diagnostic thermal imaging cameras can increase reliability of distribution networks.

Over the service life of a voltage/potential transformer, various tests are useful for ensuring safety, quality, and operation that fall in line with the specifi cations.

“OMICRONs CMC test sets are not only a solution for testing protective relays and distribution automation schemes, they enable the user to benefit from a broad range of synergies.” - Cord Mempel, Klaus Jotz

AccuLoss is a complete three-phase transformer measuring system designed for power frequency testing and calibration of medium and large power transformers, large motors and turbines.

This article describes an innovative solution to test current transformers at all lifecycle stages by using a sophisticated testing method known as “the modeling concept”.

To keep the device’s technology at the high level required by its continuously changing working environment, the CT Analyzer has been reworked once again.

Performing a range of standard electrical tests on a regular basis has proven to be an effective way of gaining reliable insight into the operating condition of transformers. But, this has been a time- and cost-intensive job in the past. A true three phase test system can really make a difference.

Rishabh is having the complete basket of low tension current transformers manufactured in a world class CT manufacturing setup consisting of an automatic testing facility for all CTs with a printed Test Certificate...- Santosh R. Bhangale

TRAX is not just another multi-functional test instrument, but rather many intelligent instruments built into one box. The software includes a number of apps, making it fast and easy to perform a large range of different tests. The hardware offers unmatched flexibility and the range of cables and accessories adding even more flexibility, making the TRAX an efficient and time saving system for any user in the world...

There is only one instrument to unpack, power up and configure; the same cable set is used for a whole range of measurements, so the connections only need to be made once; and, when carrying out a range of tests, users of multifunction instruments move quickly and easily from app to app, rather than having to go from instrument to instrument... - Peter Fagerström

To aid in the organization of a corporate or personal library, Megger is introducing a comprehensive series of Transformer Life Management bulletins that broadly cover the fundamentals of managing the life of a transformer...
