The Megger TRAX 280 is a multifunction transformer and substation test system for diagnostic testing of medium- and high-voltage electrical plant. It supports a wide range of transformer and substation tests, including transformer turns ratio, winding resistance, excitation current, short-circuit impedance, demagnetisation, tap changer dynamic resistance, contact resistance, CT/VT testing, circuit breaker analysis and primary injection testing. The system is fitted with the tan delta / power factor add-on, enabling capacitance and dielectric dissipation factor measurements for insulation condition assessment up to 12 kV. Typical applications include transformer condition assessment, bushing and insulation diagnostics, circuit breaker testing, failure investigation, research, teaching and industry consulting.
