Microtest Transformer Test System

The Microtest Transformer Test System measures turns ratio, inductance, DC resistance, leakage inductance, interwinding capacitance, polarity, phase, and hipot/insulation resistance in automated sequences with pass/fail sorting and statistical process control for power transformers, signal transformers, current transformers, inductors, and chokes.

Test Parameters

Parameter	Application
Turns Ratio	Primary-to-secondary ratio verification
Inductance	Primary and secondary winding inductance
DC Resistance	Winding resistance for copper loss calculation
Leakage Inductance	Coupling efficiency between windings
Interwinding Capacitance	Parasitic capacitance between windings
Polarity / Phase	Winding direction and phase relationship
Hipot Withstand	AC/DC voltage withstand per IEC/UL
Insulation Resistance	Inter-winding and winding-to-core isolation
Pass/Fail Sorting	Multi-parameter limit checking with disposition
SPC Logging	Statistical trend analysis for process control

The system combines all essential transformer parameters in a single test station, eliminating the need for separate LCR meters, hipot testers, and turns ratio bridges. Automated test sequences execute the complete parameter suite in seconds, with handler interfaces supporting integration into automated production lines. Barcode-triggered test program selection enables mixed-model production where different transformer variants run on the same test station.

Indian transformer and inductor manufacturers serving power supply, automotive, telecom, and industrial markets rely on automated test systems for 100% production testing. GSAS Micro Systems provides fixture design, test sequence programming, and handler interface configuration for Microtest transformer test systems deployed in Indian manufacturing facilities.
