Megger MAGNUS Step-Up Transformer

Megger MAGNUS Step-Up Transformer — Portable Instrument-Transformer Testing

The Megger MAGNUS is a portable step-up transformer that makes instrument-transformer testing fast and safe in the field. It prepares excitation (magnetisation) curves for current transformers, demagnetises CT cores and performs turn-ratio tests on voltage transformers — delivering a continuously variable high-voltage output for substation and industrial test teams in a compact, transportable package.

Key Features

• Instrument-transformer testing — prepares CT excitation curves, demagnetises CT cores and performs VT turn-ratio tests.
• Variable high-voltage output — continuously adjustable 0–2200 V AC (at 230 V input) via dial control.
• Dual outputs — independent high-voltage and mains-level outputs; up to 1 A at maximum high voltage.
• 2300 VA capacity — ample power for excitation testing, with a 30-second maximum-output duty cycle.
• Two-hand control — enhances operator safety during high-voltage testing.
• Universal input — 115 V or 230 V AC, 50/60 Hz models available.
• Portable & rugged — 356 × 203 × 241 mm, 16.3 kg, supplied in a robust transport case.
• CE compliant — built to LVD, EMC and RoHS directives.

Applications

The MAGNUS is used by substation commissioning and protection teams for current-transformer excitation (knee-point) testing, CT core demagnetisation after primary injection, and voltage-transformer ratio verification — anywhere instrument transformers must be characterised or restored in high-voltage substations and industrial installations.
