One setup, multiple tests
DV Power CVA500 Current and Voltage Transformer Analyzer
The DV Power CVA500 tests current transformers, voltage transformers, and CVTs from a single connection. Saturation and knee point, ratio, polarity, phase angle, burden, winding resistance, and insulation, all from one rugged case built for the field.
Fewer instruments in the truck, less setup time on site, and results your crews can stand behind.
One instrument that replaces several
For 20 years ProgUSA has supplied and supported the U.S. power industry with advanced diagnostic test equipment. The CVA500 fits that record. It covers the full range of CT, VT, and CVT testing that utilities, NETA firms, and industrial crews perform during commissioning, acceptance, and maintenance.
Internal multi-tap connections and output up to 2000 VAC at 60 Hz let you run saturation, ratio, polarity, phase angle, and burden tests, plus VDC for insulation and winding resistance, without swapping setups between measurements.
Full instrument transformer testing
Everything you need to verify CTs, VTs, and CVTs on the bench or in the substation.
Built for the field, trusted in the substation
Instrument transformers sit at the heart of protection and metering. When a CT or VT is off, relays misoperate and revenue metering drifts. The CVA500 gives test crews one rugged, portable tool to verify them with confidence.
It is used in utility substations, generating stations, transmission and distribution maintenance programs, acceptance and commissioning, and condition-based maintenance programs.
