SECTOR SYNCHRONISING RELAY KSQ331x2 • Low differential check synchronising, sector principle • Bi-directional synchronising • Manual and semi-automatic synchroniser • Integral voltage differential protection • ”Easy view” status presentation • Generator speed reference (analogue output) • System status output Specifications Monitored Voltage Input: Separate Aux. Supply: (Only for KSQ331G2) Monitored Voltage: (Only for KSQ331G2) Supply tolerance: Contact Rating: The digitally controlled KSQ331x2 provides both visual presentation of relative speed and phase angle relationship, and output signal necessary to permit check synchronising between two systems. KSQ331E2 is the standard and it takes the auxiliary voltage from the monitored voltage on terminal 3 & 4. KSQ331G2 have separate auxiliary supply on terminal 19 & 20. The synchronising relay will close when the incomer (generator, busbar, etc.) voltage and phase angle have been within the limits during the set retention time. Agreen lamp (CB close) indicates the close command to the breaker. Adjustments: Phase angle: Retention time: High voltage: Low voltage: Analogue output: Optional output: Temperature: Weight: Front protection: 4-30 degrees 100-600mS 2-15% of net voltage 2-15% of net voltage -10/0/+10mADC = -5/0/+5Hz difference -10/0/+10VDC (same Hz range) -20 to +70ºC 0.7kgs IP52 (IP65 optional) There is lamp indication for reference source present (BUS PWR, only when generator is powered) and incomer status (GEN PWR). Agreen lamp (VOLT OK) is lit when both voltages are within the set limits. Applications KSQ331x2 can be used both for single and three phase systems. Any two phases (or phase-neutral) can be used for synchronising as long as it is the same two phases on both side of the breaker. The unit is meant for manual and semi-automatic synchronising only. There is no compensation for the breaker closing time. For automatic synchronising, the KSQ104x2 ”SPOT ON” principle should be used to obtain compensation for breaker closing delay. User setable limits and retention time on the rear. Unit meets IEC60092-504 and relevant environmental and EMC tests specified in IEC60068/60092 and IEC61000/60533 respectively, to comply with Classification Societies requirements. Megacon is the inventor of the original, now industry standard “rotating” LED display, and a trendsetter in modern synchronisation control. The analogue -10/0/+10mA output signal can be used as speed reference to a generator controller, with polarity and amplitude proportional to frequency difference between the two systems. System status: KSQ331x2 is fitted with a system status relay. As standard the unit is powered from generator side (terminal 3 & 4), when power is ok and unit is working correctly the relay activates. It will release on alarm or when unit is not powered. Separate auxiliary supply is needed for continuously system status.

SECTOR SYNCHRONISING RELAY Low-differential SECTOR synchronising KSQ331x2 11 1 CB close command on for duration of power to terminals 1,2 & 3,4 Incomer (generator, busbar, etc.) 19 Separate Aux. Supply 20 (Only on KSQ331G2) + Description System “S” the sector synchronising principle: The KSQ331x2 is a low differential bi-directional check synchronising relay. The synchronising relay closes when the incomer (generator, busbar, etc.) frequency is close enough (diff 0,01 - 0,5Hz) to stay within the phase angle sector (S) for the set retention period (t). Sector synchronisation is the classical...
