The Megger Magnus Step Up Transformer is used to check that instrument transformers in power systems are providing test instruments and protective relay equipment with the correct outputs. The Megger Magnus Step Up Transformer can be used to check power systems before they are put into operation and/or when a fault occurs.
The Megger Magnus Step Up Transformer can be used to demagnetise current transformer cores, conduct turn-ratio tests on voltage transformers, and prepare excitation curves for instrument transformers.
Preparing excitation curves using the Megger Magnus Step Up Transformer is quick and easy:
The Megger Magnus Step Up Transformer is able to provide 1A at 2.2kV. It features a two-hand control to improve user safety.
Finally, the Megger Magnus Step Up Transformer weighs just 16kg (35 lbs) and is supplied with a special high-voltage cable and robust transport case.
The Megger Magnus Step Up Transformer is an efficient, simple-to-use and safety-optimised transformer tester.
Please note that this model is optimised for the UK/Europe and requires a mains voltage of 230V AC. Models requiring a mains voltage of 115V AC are available, please contact our sales team for further information.
