Synchroscope Training Tool

Synchronizing Criteria (typical): ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Slip Frequency: < 0.067 Hz (4 seconds per revolution) • Phase Angle: Within ±10° of 0° (12 o'clock) • Voltage Difference: Within ±5% Synchroscope Operation: ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Pointer at 12 o'clock = 0° phase difference (IN SYNC) • Clockwise rotation = Incoming FAST (higher frequency) • Counter-clockwise = Incoming SLOW (lower frequency) Best Practice: ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 1. Match voltages within 5% 2. Adjust incoming frequency to rotate slowly CLOCKWISE 3. Close breaker just BEFORE reaching 12 o'clock 4. This accounts for breaker closing time
