Engineered for the rigours of field testing, the Megger IDAX 322 Insulation Diagnostic Analyser redefines precision in assessing insulation health across bushings, current transformers, power transformers, and generators. Harnessing Dielectric Frequency Response (DFR), it delivers comprehensive measurements of capacitance (10 pF–100 µF), tan delta/power factor, and moisture content with a stellar 0.5% accuracy, covering frequencies from 10 µHz to 1 kHz. Its 2 kV peak output and 50 mA capacity make it a powerhouse for low-capacitance objects like bushings, where it detects moisture ingress and partial discharges—critical given bushings contribute to 17% of transformer failures and up to 80% of related fires.
Dual ammeters allow two simultaneous measurements, slashing test times, while the Individual Temperature Correction (ITC) ensures results are normalised to 20°C or 25°C for reliable comparisons. Tailored for RBP, OIP, RIP, RIS bushings, and custom materials, the IDAX 322 adapts effortlessly to diverse applications. The optional DFR500 switchbox transforms bushing and transformer testing by enabling single-connection setups, reducing hazardous re-connections and enhancing safety. Weighing 13 kg and paired with a practical soft backpack for its 21 m cables and bushing tap adapters, it’s built for demanding environments. The IDAX 5.1 software simplifies workflows with automated analysis, presenting clear results to guide maintenance decisions.
Compliant with standards like IEEE C57.161-2018, the IDAX 322 empowers engineers to optimise load capacity, extend equipment longevity, and avert catastrophic failures in vital power infrastructure.
