CHECK SYNCHRONISER RELAY & BUS/GENERATOR COUPLER

CHECK SYNCHRONISER RELAY & BUS/GENERATOR COUPLER

Product catalog summary

Specifications:
The KSQ332EJD1 is a precision check synchroniser and bus/generator coupler designed for both visual speed rotation and phase angle relationship monitoring. It includes integral voltage differential protection and features an 'Easyview' status presentation. The device supports bi-directional synchronising and can be used for both single and three-phase systems. It is suitable for manual and semi-automatic synchronising, with user-settable limits and retention time.

Procedures:
The synchronising relay closes when the voltage and phase angle are within set limits for a specified retention time. A green lamp indicates the close command to the breaker. The unit provides lamp indications for reference source presence and incomer status, as well as a voltage comparator indication.

Standards and Compliance:
The KSQ332EJD1 complies with IEC60092-504 and relevant environmental and EMC tests specified in IEC60068/60092 and IEC61000/60533. It meets the requirements of Classification Societies.

Applications:
The device is used for synchronising two different system voltages or as a bus/generator coupler. It is particularly useful in scenarios where the bus and/or generator is 'dead'.

Technical Specifications:

Monitored Voltage Input: 100-120, 200-240, 380-415, or 440-460VAC, 40-70Hz
Auxiliary Supply: AC or DC options available
Contact Rating: AC: 100VA - 250V/2A max; DC: 50W - 100V/1A max
Adjustments: High/Low voltage limit: 2-15% of net voltage; Phase angle: 4-30 degrees; Retention time: 100-600mS
Temperature Range: -20 to +70ºC
Weight: 0.7kgs
Front Protection: IP54 (IP65 optional)

Recommendations:
For applications requiring automatic synchronising, the KSQ104 'SPOT ON' principle is recommended to compensate for breaker closing delay. The sector synchronising principle allows for interrelated synchronisation accuracy and speed, but may not be suitable for fluctuating loads.

Ordering Information:
Product type: KSQ332EJD, with options for auxiliary supply and network voltage.

When used as a bus/generator coupler, the CB close relay will energise when either the bus and/orthe generator is "dead" AND the enable signal is closed. The synchronising relay will close when the voltage and phase angle has been within the set limits for the set retention time. Agreen lamp will indicate the close command to the breaker. There is lamp indication for reference source present (BUS PWR) and incomer status (GEN PWR). And an additional lamp for the voltage comporator (Voltage OK), green LED is lit when gen. voltage is within voltage set limits. KSQ332EJD1 is only available with separate AC or DC auxiliary supply. Applications KSQ332EJD1 can be used both for single and three phase systems. Any two phases (also 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 since there is no compensation for the breaker closing time. For automatic synchronising then the KSQ104 "SPOT ON" principle should be used to get compensation for the breaker closing delay.
