DvPower - Multi-tap Current and Voltage Transformer Analyzer CVA500
The new powerful DV Power Current and Voltage Transformer Analyzer CVA500 with a large 10.1-inch touchscreen display represents an evolution testing technology that provides user-friendly and fast test ex*****on of the full range of current transformer (CT), voltage transformer (VT), and capacitive voltage
transformer (CVT) tests.
CVA500 simultaneously measures CT knee point, turns ratio, polarity, and winding resistance in all taps. The automated test feature performs all these measurements in one test, including CT demagnetization, insulation resistance, and burden test, without any operator intervention. This significantly reduces testing time and helps to avoid possible issues caused by operators.
Application
The list of instrument applications includes a full range of tests:
• Saturation curve and knee point for CTs
• Ratio and phase errors for 4 different burdens and 8 different primary currents, for CTs
• Composite error for CTs
• Instrument security factor FS for IEC-based measurement CTs
• Accuracy limit factor ALF for IEC-based protection CTs
• Secondary terminal voltage Vb for IEEE-based protection CTs
• Turns ratio, polarity, and phase angle tests for CTs, VTs, and CVTs
• Demagnetization for CTs
• Winding resistance for CTs, VTs, and CVTs
• Insulation resistance for CTs, VTs, and CVTs
• Burden test for CTs, VTs, and CVTs
