[Legacy Report] Motor Bus Transfer Applications: Issues and Considerations

#Motor #Bus #Transfer #Applications: #Issues #and #Considerations

That transferring within the ANSI C50.41 prescribed time limit criterion may actually damage your motors? Learn why time is not an optimum transfer performance prediction metric.

• That using the ANSI C50.41 prescribed resultant per unit V/Hz criterion does not correlate with reacceleration torque? See oscillographs results that show transfer torque is the key metric and that per unit V/Hz is not a positive success indicator.
• The various initial phenomena across the alternate source breaker that absolutely would preclude an immediate Fast Transfer.
• When Fast Transfer is not possible, In-phase transfer offers a whole new dimension in transfer opportunities.
• That coordinated use of the fast and in-phase transfer can offer safe transfer and maintain process continuity? See how the settings are developed without the need for a study or ringdown test.
• Analysis of live Motor Bus Transfer field results at power generation and petrochemical facilities are presented to derive and propose a new transfer criterion based on the ratio of the aggregate peak torque after the transfer to the aggregate load torque prior to transfer.
• A new relay test protocol is proposed to fill the need for industry performance requirements of devices supervising Motor Bus Transfer.
• Explore both field and test results as In-Phase and Fast Transfer methods coordinate synchronous transfer under widely varying dynamic conditions.
