Description

Transformer diagnostics in a single instrument.

The Megger TAU3 True Three-Phase Transformer Winding Analyzer is designed for electromechanical testing of power, distribution, and instrument transformers.

The multifunctional TAU3 allows multiple transformer tests to be performed with a single connection. This reduces testing time, minimizes lead reconnections, and improves operational safety and productivity.

Key capabilities of the TAU3 include:

• Polarity and transformer turns ratio testing.
• Transformer winding resistance measurement.
• Transformer demagnetization.
• Short-circuit impedance measurement.
• Transformer efficiency assessment.
