• Quick and easy preparation of excitation curves for instrument transformers
• Demagnetize current transformer cores
• Conduct turn-ratio tests on voltage transformers
• Two-hand control enhances personal safety

When power systems are put into operation or when faults occur, it becomes necessary to check the instrument transformers to make sure that they are providing test instruments and protective relay equipment with the correct outputs.

MAGNUS™ permits you to prepare excitation curves for instrument transformers quickly and easily.

MAGNUS is also used to demagnetize current transformer cores and to conduct turn-ratio tests on voltage transformers. Even though it weighs only 16 kg (35 lbs), it provides 1 A at 2.2 kV. Two-hand control enhances personal safety.

As standard, MAGNUS is delivered with a special high-voltage cable and a robust transport case.

State-of-the-art power transformer testing

TRAX is the most complete power transformer diagnostics test system. It integrates fundamental and advanced tests with unique features to ease analysis and evaluation of a transformer's overall condition in the field

• • WRM at 100A and 50V compliance voltage for faster saturation of large or high inductance transformers.    
• •  True dynamic resistance measurement of OLTC (Megger innovation) to determine the real magnitude of transition resistances and transition times.
• • Adaptive demagnetization for the fastest and most efficient demagnetization on the market.
