Function：

1. The digital three-phase shifter can reach an advance or hysteresis shift phase of any angle within 0 to 360 degrees;

2. The digital three-phase shifter uses three-phase three-core column transformer, Y0 wiring method, each with four equilateral windings, intersecting different angles, forming a hexagon connected to the corner, The six sides have a total of twelve taps, namely the twelve gears, 30 degrees per gear, three-phase synchronous adjustment, fine adjustment consists of three coaxial autographs and capacitors, so that the output three-phase is in the range of 0 ~ 360 degrees. Synchronous adjustment to ensure the balance of the three-phase output;

3. The digital three-phase shifter has the characteristics of convenient operation, small size, low noise, and good output waveform. It can meet the single-phase and three-phase AC power, phase and other instrumentation test verification, and the test verification of the meter, etc. Among the calibration devices for the electric meter.
