True three power test system for power transformer testing

The world’s first portable & light weight, three-phase power transformer test system which supports all common electrical tests on single phase and three phase, power and distribution transformers for routine and diagnostic testing on-site or during factory acceptance tests (FAT).

One system for multiple tests

Just three cables are needed to be connected to perform various tests with TESTRANO 600:

• Transformer Turns Ratio
• DC Winding Resistance
• Dynamic Resistance
• Demagnetization
• Short-Circuit Impedance / Leakage Reactance
• Frequency Response of Stray Losses
• OLTC Scan / Dynamic Resistance (DRM)
• Vector Group Check
• Cooldown Test
• Power Losses at Low Voltages
• Tan Delta with 12 kV or 15 kV Source
