Maintain Plant Process!

Avoid motor damage and costly shutdowns by ensuring the orderly transfer of the sources to your motors. Our complete Syncrotran® System and component relays properly execute the transfer of your critical motor loads.

Your Benefits:

Match the Conditions at the Instant of Transfer—

• Our Syncrotran® System and component relays address fast (high-speed synch-check), in-phase (high-speed synchronizing) and residual (undervoltage) transfer applications
• You can use component relays for specific transfer types, or the Syncrotran® System that automatically selects the best method from the three types during the transfer interval

Enhanced Power Delivery and Safety—

• Dynamically adapts to source conditions, composite motor bus inertia and voltage decay characteristics to automatically determine the best method for transfer— even under adverse fault conditions
• Mitigate the effects of overvoltage, high volts-per-hertz (overexcitation) and hard loading (mechanical shock) to your motors by assuring source transfer with a minimum of electrical and mechanical stress
• Avoid needless power plant shutdown due to unavailability of auxiliary services after faulty source transfer

Syncrotran^® System
The utility-grade Syncrotran System consists of a Transfer Logic Controller and either a Power Transfer Relay or a High Speed Sync-Check Relay. The system performs all of the necessary logic and control functions for motor bus transfers in two directions by automatically selecting from either fast, in-phase or residual voltage methods. The relays allow the Transfer Logic Controller to supervise a fast transfer by monitoring the phase angle between the motor bus and the new source, and blocking transfer if the angle is excessive. If fast transfer is impossible because of excessive angle, the Power Transfer Relay offers the option of closing the motor bus in-phase with the new source at the very next pass through zero degrees. Should system conditions prevent transfer by either method, the Transfer Logic Controller contains a circuit that measures bus voltage, regardless of the frequency, and allows a residual transfer to occur when the motor bus voltage has decayed to a safe level.
