State-of-the-art power transformer testing
TRAX is the most complete power transformer diagnostics test system. It integrates fundamental and advanced tests with unique features to ease analysis and evaluation of a transformer’s overall condition in the field
• WRM at 100A and 50V compliance voltage for faster saturation of large or high inductance transformers.
• True dynamic resistance measurement of OLTC (Megger innovation) to determine the real magnitude of transition resistances and transition times.
• Adaptive demagnetization for the fastest and most efficient demagnetization on the market.
Leading tan delta / power factor testing technology
With the TDX120 add-on, the TRAX becomes are the most advanced tan delta /power factor testing instrument on the market. Its unique features allow better assessment of the insulation system.
• Tan delta / power factor testing at 12 kV and 500 mA for successful testing of high capacitance objects without the use of an external inductor.
• Individual Temperature Correction (ITC – Megger innovation) for accurate and automated temperature normalization to 20 °C, to avoid use of outdated correction tables. True correction based on dielectric response analysis.• Voltage Dependence Detecion (VDD – Megger innovation). Automatic detection of voltage dependence and alert to run a tip-up test. This is of particular value to oil-paper insulation systems, for which a stepped voltage test is not normally performed.
• Narrowband DFR testing capabilities from 1 – 500 Hz.
• Megger state of the art Individual Temperature Correction algorithm and 1 Hz power factor/dissipation factor/tan delta assessment
