Capacitor Voltage Transformer (CVT) Turns Ratio Tester
Description of Capacitor Voltage Transformer (CVT) Turns Ratio Tester
The Vanguard CVT-765 is a microprocessor-based, single phase, automatic, transformer turns-ratio tester. This portable test unit is specifically designed to measure the turns-ratios of Capacitor Voltage Transformers (CVT’s).
The CVT-765 determines the transformer turns-ratio using the IEEE C57.12.90 measuring method. It uses a 7440 Vac excitation voltage source to accurately measure the turns-ratio of Capacitor Voltage Transformers with a rating of up to 765KV. The transformer turns-ratio is determined by precisely measuring the voltages across the unloaded transformer windings.
- Standalone or computer-controlled
- Can test CVT’s rated up to 765 KV
- Displays turns-ratios from 75-15,000
- Calculates turns-ratio percentage error when nameplate voltages are provided
