Concurrent Transformer Test System and Method

摘要

A tester for testing a transformer is provided. The tester comprises a primary voltmeter and a plurality of secondary voltmeters. The tester may also comprise an ammeter in series with a voltage source configured to apply voltage to the transformer. The primary voltmeter is configured to measure voltage induced across a primary winding of the transformer, while the secondary voltmeters may simultaneously measure voltage outputs at secondary windings of the transformer. The tester is configured to calculate ratios, saturation curves, and knee points for multiple winding combinations based on the measurements simultaneously obtained by the ammeter and the primary and secondary voltmeters.

1. A method for testing a transformer, the method comprising:
applying an input voltage to a secondary winding of the transformer in order to induce a voltage in a primary winding of the transformer; and simultaneously measuring secondary voltages in a plurality of secondary windings of the transformer in response to applying the input voltage, wherein a plurality of secondary voltmeters are used to measure the secondary voltages as a primary voltmeter measures the induced voltage in the primary winding.
