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. The Programma Magnus can be used for preparing excitation curves for instrument transformers and for demagnetizing current transformer cores.

Programma Magnus Features:
• Prepare excitation curves for instrument transformers.
• Demagnetize current transformer cores.
• Conduct turn-ratio tests on voltage transformers.
• Weighs only 16 kg (35 lbs).
• Two-hand control enhances personal safety.
