TWA Standard Series -
Amperis sl
The TWA standard series instruments are designed to measure the resistance of six coils and simultaneously analyze the three-phase tap changer on load of the primary and secondary transformer coils (provided by model TWA40). This is done in a single cable configuration, with test currents up to 40A. Each transformer configuration has a special measurement algorithm that is optimized for rapid stabilization of test results. The TWA instruments generate a true DC current without ripple. Both current injection and magnetic circuit energy discharge are automatically regulated.

RMO TW Series -
Amperis sl
The RMO-TW instrument can perform a simple, fast and reliable verification of a transformer on-load tap changer. This instrument allows measurements of a winding resistance at each tapping position of an on-load tap changer without discharging between tests. Problems with OLTC switching, such as interruption, can be detected with these measurements. The results are displayed on a backlit LCD screen.
