Product Description

Descriptions 

The GOLD GDVA test set is a lightweight, robust, portable unit capable of testing both current and voltage transformers. At less than 15Kg the GDVA is a highly portable unit that also offers accuracy in testing. Capable of performing saturation, ratio, polarity, winding resistance, and insulation tests on current transformers, the GDVA can also be used for testing metering and protection class voltage/potential transformers.

The GDVA provides a microprocessor controlled variable voltage and current output along with precision instrumentation for automatically testing single and multi-ratio CT's and PTs. The GDVA makes testing CTs easy. It will directly connect to multi ratio CTs and perform all tests saturation, ratio and polarity, winding resistance, and insulation on all taps with the push of a button and without changing leads. This greatly reduces testing time.

The GDVA can be controlled via its large, full color, high resolution, sunlight readable TFT LCD touch screen display. This interface allows the user to perform manual and automatic testing quickly and easily using the manual test screen, or by using ore-constructed test routines. The large color display also permits the user to easily read all pertinent data while the test is being performed and provides the ability to view the results when the test is complete.
