Transformer Test Set

CTMP 2012 - Blue Box Test Equipment (Calvada Technologies)

The CTMP 2012 offers integrated instructions for easy familiarization and enhanced productivity. The instrument performs the classic voltage ratio test and displays the primary and secondary voltages and the angle between them (polarity). Two X1 - X2 excitation output voltage ranges, 0-200V and 0-1000V, facilitate accurate measurement of CT ratios to 100,000 to 5. Output voltage metering autoranges to a 0-20V scale to maintain accuracy on low ratio transformers. The H1-H2 input range for current transformer testing is 0-0.32V to allow high resolution with the typical one turn primary used to perform a CT ratio test.
