Megger Magnus Step-Up Transformer

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 (now called the Megger Magnus) permits you to prepare excitation curves for instrument transformers quickly and easily. It is also used to demagnetise 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. As standard, MAGNUS is delivered with a special high-voltage cable and a robust transport case. 230V & 115V mains voltage versions of the Magnus are available. Please choose which option from the dropdown above. FEATURES 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. Megger Magnus Specifications Measuring Outputs Voltage 100/1, (max load of 1 MΩ). Inaccuracy +1,5%.
