Common Electrical Tests on Power Transformers
Regularly performing a range of standard electrical tests has proven an effective way to gain a reliable insight into the operating condition of your transformers and can extend their lifespan.
These conventional testing methods include measuring a number of parameters, such as the short circuit impedance, transformers ratio, magnetizing current, winding resistance and dynamic winding resistance of the tap changer. With our testing system, you can use a single device to determine all of these parameters in an easy way. Once you have completed the testing, you can also demagnetize the transformer.

TESTRANO 600 + PTM
TESTRANO 600 is the world’s first portable, three-phase test system which supports all common electrical tests on single- and three-phase power and distribution transformers.
TESTRANO 600 provides you with a convenient way of testing to gain a comprehensive insight into the condition of every part of your power transformer. It can be operated using TESTRANO TouchControl on the integrated display, or by using our Primary Testing ManagerTM software on your laptop. This makes it ideal for routine and diagnostic testing onsite or during factory acceptance tests (FAT).
