The Activation Gap: Why Backup Relay Systems Are Often Slower Than the Failures They Are Meant to Absorb
Detection speed is only half the equation in relay failover engineering. The interval between confirming a relay failure and completing the activation of its backup—what we call the activation gap—is frequently longer than the detection window and almost always underestimated. This performance analysis dissects the mechanical causes of that gap and challenges operators to rethink the trade-offs between speed and validation.
