The ZXCBB PT Turn Ratio Meter Calibration Transformer is precision testing equipment designed to verify the accuracy, resolution, and group configuration of instrument transformer turn ratio testers. This system combines a standard three-phase PT with an inductive voltage divider to deliver comprehensive testing capabilities for electrical measurement instruments.

Preset turns ratio range from 1.111111 to 0.0000001. For standard ratios including 1, 2, 5, 10, 20, 50, 100, 200, 500, 1000, 2000, and 2500, the inductive voltage divider provides precise dial scale settings. Operates effectively at 20%~100% of the 200V rated voltage.

Configure divider values between 0.1000000~0.0999900, corresponding to turn ratios of 10.000~11.100. Provides clear display value changes for accurate resolution verification.

Direct connection testing with divider set to 1.000000, enabling 1/1 self-checking functionality. Includes inductive isolated winding for 1/1 isolation testing where required.

Standard three-phase PT supports 12 group configurations with turn ratio options of 10, 100, or 1000. Each single-phase error remains below 0.05%.

Comprehensive Z-type testing with 10 group configurations at 100 turn ratio. Each phase secondary winding maintains error below 0.05%.
