The Megger MAGNUS Step-up Transformer is a versatile, user-friendly tool designed to streamline critical testing of instrument transformers in power systems, ensuring reliable outputs for protective relays and test instruments. Capable of delivering 1 A at up to 2200 V AC (or 2000 V at 115 V mains), it excels in preparing excitation curves for current transformers (CTs) with a straightforward process of increasing voltage and recording current and voltage values. Its demagnetisation function, achieved by gradually reducing voltage to zero, safeguards CT cores from residual magnetism, while its capability to perform turns-ratio tests on voltage transformers ensures comprehensive diagnostics with 1% accuracy for voltage and current measurements.

Weighing just 16 kg, the MAGNUS is highly portable, arriving with high-voltage cables and a sturdy transport case to withstand demanding field conditions. The two-hand control mechanism enhances safety during high-voltage operations, complemented by built-in protections like a thermal cut-out and miniature circuit breaker. Suitable for continuous low voltage testing at 250 V AC and 6 A, it adapts to various scenarios, from routine commissioning to fault diagnostics. Operating reliably between 0°C and 50°C, the MAGNUS aligns with standards like IEC 61010-1 and is an essential asset for engineers aiming to maintain the integrity of power system components, preventing costly failures with precision and ease.
