World’s First Portable, Three-Phase Test System

TESTRANO 600 paves the way to quick and easy three-phase testing of power transformers… 


 With TESTRANO 600, OMICRON has developed the world’s first portable, three-phase test system, which supports all common electrical tests on power transformers. Weighing just 20 kg/44 lbs, it is ideal for routine and diagnostic testing on-site and during Factory Acceptance Tests (FAT). In addition, its innovative design significantly reduces wiring efforts, cutting down testing time to one third compared to conventional single-phase testing.

One system– multiple tests

  By using TESTRANO 600, operators can perform multiple test without rewiring. Just three cables have to be connected: One to the high-voltage side, one to the low-voltage side and one to the tap changer of the power transformer. With this common setup, transformer turns ratio, exciting current, DC winding resistance, dynamic resistance, short-circuit impedance / leakage reactance as well as frequency response of stray losses (FRSL) can be measured.

  By combining TESTRANO 600 with the accessory CP TD1, it can also test power/dissipation factor and capacitance up to 12 kV.

Flexible and smart operation

  In order to fulfill individual customer requirements, TESTRANO 600 offers a flexible operating design. It can be operated via the smart TESTRANO TouchControl on the integrated touch display or by using the established Primary Test Manager software on the laptop.
