TESTRANO 600

TESTRANO 600 is a revolutionary three-phase transformer test system that performs all major tests with minimal reconnection effort. It replaces multiple traditional test devices by combining winding resistance, ratio measurement, short-circuit impedance, OLTC testing, magnetization, and more into one unit. TESTRANO 600 greatly accelerates testing workflows through its automated test sequences and guided PTM interface. The device significantly reduces testing time in substations, especially during transformer commissioning or major maintenance. Its three-phase design ensures symmetric testing, improved accuracy, and reduced risk of wiring errors. TESTRANO 600 is rugged, portable, and suitable for applications from distribution to large power transformers.
