Power Transformer Testing with One-Time Test Connection

 

TESTRANO 600 is the world’s first portable, three-phase test system, which supports all common electrical tests on power transformers. Weighing just 44 lbs / 20 kg, 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.

TESTRANO 600 was demonstrated at the Knoxville Utilities Board (KUB) in Tennessee as part of the T&D HOW video series. With the new three-phase system, power transformers can be tested using a one-time test connection. Thus, common diagnostic tests such as 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 with a single setup. By combining TESTRANO 600 with the accessory CP TD1, it can also test power/dissipation factor and capacitance up to 12 kV.
