The Megger MTO210 is a high-precision instrument designed to measure the DC resistance of transformer windings, ensuring accurate assessment of winding condition and tap changer performance. It is widely used during commissioning, maintenance, and diagnostics to detect issues such as loose connections, winding deformation, or contact problems in OLTC/DETC systems. Its fast measurement capability reduces test time, especially on large power transformers.
Technical Highlights: Test current range: up to 10 A DC | Resistance measurement range: 0.1 µΩ to 2 kΩ | High accuracy with temperature correction | Dual-channel measurement for faster testing | Built-in demagnetization function.
Delivers reliable, repeatable results essential for transformer health evaluation.
