The digitally controlled KSQ104x2 provides both visual presentation of voltage differential and relative speed and phase angle relationship and speed control output signals necessary to achieve fast automatic “spot-on” synchronizing between two systems. KSQ104x2 is a direct replacement for the “traditional” KSQ104 and KSQ105.
Its many important features contribute to make KSQ104x2 simply the best choice available for synchronising in any automatic generator control system (PM-system).
KSQ104F2 is the standard and it takes the auxiliary voltage from the monitored voltage on terminal 3 & 4.
KSQ104G2 have separate auxiliary supply on terminal 19 & 20.
KSQ104x2 is used for both single and three phase systems. Any two phases (or phase-neutral) can be used for synchronizing as long as they are the same two phases on both sides of the breaker. The synchronizer is rated for continuous operation and can be left connected when not in use.
To adapt the functionality of KSQ104x2 to any specific application, the direction of approach to synchronizing (LEAD, LAG or NEUTRAL) can be selected as required:
- LEAD (incomer faster than bus)
- LAG (incomer slower than bus)
- NEUTRAL (bi-directional)
