CVA500 is designed for utilities, service companies, and laboratories that need reliable CT, VT, and CVT testing capabilities in a focused, professional, and cost-effective solution.

Built for serious field work, CVA500 combines automated test execution, one-time connection for multi-tap CTs, standard-compliant measurements, and an intuitive 10.1-inch touchscreen interface to help technicians perform tests faster and with greater confidence.

From CT saturation and knee point testing up to 2 kV to turns ratio, polarity, winding resistance, insulation resistance, burden testing, and accuracy class assessment, CVA500 provides advanced functionality for a wide range of instrument transformer testing applications.

Focused on What Matters in the Field:
One-Time Connection for Multi-Tap CTs
Connect once and perform multiple measurements without repeated cable reconnection.

Automated Test Mode
Run key measurements in one automated sequence, reducing manual work and saving valuable testing time.

Standard-Compliant CT Analysis
Perform saturation, knee point, ratio and phase error, composite error, FS, ALF, Vb, and accuracy class assessments.

Practical Field Operation
A large touchscreen display, built-in thermal printer, and DV-TR software support efficient testing, analysis, and reporting.

For teams looking to upgrade their instrument transformer testing process, CVA500 offers a smart balance of advanced functionality, reliable performance, intuitive operation, and excellent long-term value.
