Product Description

GDVA-405 Current & Potential Transformer CT PT Analyzer CT Meter

Product Description

 

GDVA-405 Current & Potential Transformer CT PT Analyzer CT Meter is a comprehensive CT and PT analyzer.

GDVA-405 Current & Potential Transformer CT PT Analyzer CT Meter is constant voltage and current is highly stable. DSP system controls the constant voltage and current source output and amplitude. This source generates AC of 0-125V and or DC of 0-0.5A current to sample CT.

The DSP system besides controlling the sources, also samples data and communicates with the internal computer. Display screen is large LCD with touch pad.

GDVA-405 Current & Potential Transformer CT PT Analyzer CT Meter is highly accurate with high noise immunity and is very user friendly.
