We are proud to present the CVA500, our latest innovation in instrument transformers testing technology.

Designed for comprehensive analysis of Current Transformers (CTs), Voltage Transformers (VTs), and Capacitive Voltage Transformers (CVTs).

With its intuitive 10.1-inch touchscreen interface, the CVA500 allows quick test configuration and execution.

Its standout feature is one-time connection to all CT measurement terminals—including the primary side and up to five secondary taps—enabling multiple tests to be performed in a single automated sequence.

This minimizes human error and significantly reduces test time.

Key Test Capabilities Include:

• Burden testing for CTs, VTs, and CVTs
• CT demagnetization, saturation curve, and knee point
• CT ratio and phase errors across multiple burdens and currents
• CT composite error, FS (Instrument Security Factor), and ALF (Accuracy Limit Factor)
• Secondary terminal voltage (Vb)
• Turns ratio, polarity, and phase angle for VTs, and CVTs
• Winding resistance and insulation resistance for CTs, VTs, and CVTs
