Transfer Function of Power Transformer. Part 4. Additional Measurements on Test211 Winding

摘要

The project for developing a transfer function method for transformer testing was211u001estarted at HUT High Voltage Institute in summer 1997 and the results were 211u001ereported in June 1998. This report gives results of additional measurements on 211u001ethe separate test winding at high voltage and low voltage lightning impulses. 211u001eMeasurements consisted of interference checks and artifical faults like galvanic 211u001efaults over nine turns, faults using pressurized spark gaps and also series 211u001econnections of a resistor and a spark gap.
