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
