EE1137 : Transformer Factory Test

This practical and highly-interactive course includes various practical sessions and exercises. Theory learnt will be applied using our state-of-the-art simulators.

This course is designed to provide participants with a detailed and up-to-date overview of Transformer Factory Test. It covers the transformer types and applications, transformer construction and core types, cooling methods and transformer rating nameplate interpretation; the transformer manufacturing process and standards for transformer testing; the high-voltage test laboratories overview, test instruments and calibration, safety precautions in HV testing and grounding and shielding practices; and the factory test plan and documentation, core magnetization and visual inspection.

Further, the course will also discuss the winding resistance measurement, resistance testing, temperature correction, test procedure and connection methods and acceptable limits and troubleshooting; the insulation resistance and polarization index, turns ratio and phase displacement test; the no-load loss and current measurement, short-circuit impedance, load loss and vector group verification; and the voltage (AC withstand) test, induced voltage (double frequency) test and partial discharge measurement.

During this interactive course, participants will learn the lightning impulse test (type test), switching impulse test (special test) and bushing and OLTC insulation testing; the temperature rise test (type test), oil and gas analysis, magnetic balance and zero sequence impedance, noise level and vibration test and OLTC and tap changer functional test; the special tests for customer requirements, dielectric test demonstration, data recording and interpretation; and the failure analysis in factory testing, FAT reporting and client witnessing.
