Electrical Tests on Power Transformers

Benefits of this solution

One system – multiple tests

With TESTRANO 600 you can measure transformer turns ratio, DC winding resistance, dynamic resistance, leakage reactance / short-circuit impedance and frequency response of stray losses as well as demagnetize your transformer.

Easy and fast testing setup

All these tests can be performed with one common setup and on all three phases simultaneously. Thus, TESTRANO 600 cuts down testing time to one third.

Flexible operation

TESTRANO 600 can be flexibly operated using TESTRANO TouchControl on the integrated display, or by using a laptop with the Primary Test Manager software.

Powerful and compact

The three integrated sources ensure measurements with high accuracy and make it a powerful system (3 x 33 A DC and 400 V AC). With a weight of just 20 kg / 44 lbs, it is ideal for on-site and FAT testing.

“TESTRANO 600 is the world’s first portable, three-phase test system, which supports most common electrical tests on power transformers.”
