Direct Transfer Trips: A Primer

A lot is required of policymakers these days – in order to get policies right they often need to understand the basics of science and technology, sociology and economics, legal terminology and a host of other issues that can affect policy decisions. As a result, they often rely on experts like Michael Sheehan, who participates in state commission proceedings on behalf of IREC, helping policymakers understand how engineering principles should be incorporated into interconnection policy decisions. I recently had a chance to ask him about Direct Transfer Trips (DTT or Transfer Trip), a technical term I’d heard often but didn’t really know much about.

Increasingly, DTT requirements are a topic of discussion regarding updates to interconnection procedures. However, it can be difficult for those of us who lack a firm understanding of electrical engineering to know what this term means, and when DTT requirements may be necessary. From what I learned, Transfer Trips are a communication device between a generator and a substation through which a communication signal can be sent to disable a generator in the event of a power interruption.  When a substation relay detects fault on the electric power system (EPS), it sends a “trip” signal to the generator that trips the generator’s breaker and disables it so the generator ceases to energize the local power grid.
