F6050 Universal Time Synchronizer

GPS precision and flexibility for end-to-end testing

GPS synchronization is necessary for end-to-end testing of the complete line protection and communication scheme under all fault conditions, including external faults and current reversals. Doble's F6050 Universal Time Synchronizer extends the benefits of GPS-synchronized end-to-end testing to your entire power system, regardless of location, eliminating the need for costly staged fault testing.

Used in conjunction with the F6150 Power System Simulator, the F6050 provides end-to-end synchronization where access to GPS signals is not available. After acquiring an initial signal, the F6050 continues generating simulated GPS time accurately for eight hours. You can increase the reliability and confidence of your power system protection performance by testing critical lines that are inaccessible to a GPS signal.

Features

• Extra-High Precision. Rubidium crystal provides 1 pulse per second (pps) output, ±10 microseconds.
• Extendability. Battery backup guarantees accuracy for 8 hours
• Reliability. Rugged construction and proven state-of-the art design provides laboratory accuracy in field environments.
• Versatility. Replay actual transient end-to-end events in the field to analyze unexpected operations
• Flexibility. The F6050 Universal Time Synchronizer generates timing signals using three methods:
  • Whenever the unit is powered up or on external reset, the F6050 uses self-generated or simulated GPS time that starts at 00:00:00 (hh:mm:ss).
    
  • When connected to an F6885 GPS Satellite Receiver Interface, the F6050 synchronizes to UTC time.
  • When connected to a 50/60Hz, 120/240 VAC main signal, the F6050 generates a 1 pps signal based on the positive-going zero crossing of the AC main signal.
