Microtest 9560 Automatic Transformer Test System

The Microtest 9560 Automatic Transformer Test System is the most comprehensive solution in the Microtest transformer testing portfolio, integrating low-voltage parameter measurement, hipot safety testing, impulse winding testing, and excitation current measurement with a built-in AC source across 21 channels. The integrated AC source enables excitation current and core loss measurement at actual operating voltages and frequencies, a critical test for power transformers where core material performance directly impacts efficiency and thermal behavior.

Excitation Current and Core Loss Measurement

Excitation current measurement reveals core defects, improper air gaps, and material degradation that other tests miss: a transformer with correct turns ratio and adequate insulation can still fail in the field if core losses are excessive or excitation current is anomalous. The built-in AC source applies the actual operating voltage and frequency to the primary winding, measuring the resulting excitation current profile.

Four-Function Integration

By combining LV parameter measurement, hipot withstand, impulse winding verification, and excitation current testing in a single automated sequence, the 9560 provides the most thorough production-line transformer qualification available. Programmable test sequences and handler interfaces support fully automated operation with barcode-driven recipe selection.

Applications

High-volume power transformer, isolation transformer, and switching transformer production facilities deploy the 9560 where both electrical performance and safety compliance are non-negotiable. The system is the definitive choice for manufacturers whose OEM customers require excitation current data and impulse test results alongside standard LV and hipot parameters.
