New Surge Testing
Technique for High Inductance Equipment
An iPresentation Tutorial by
George Frey, Baker Instrument Co.
This 8
minute iPresentation tutorial covers a new technique that has been
developed to provide valuable information on DC or direct current
windings. The circuitry behind the surge test has been improved to
provide substantially better ring patterns for these types of hard to
test windings due to their turn characteristics. A much greater degree
of sensitivity is also found in the L-L EAR or Line-Line Error Area
Ratio calculations. With these two data points DC motor problems can be
identified and recorded for trending and troubleshooting.
