Plasma inducer

A plasma inducer was a device that malfunctioned on the USS Enterprise (NCC-1701-D) in the anti-time past before the ship's maiden voyage to Deneb IV and, given Jean-Luc Picard's preexisting knowledge of the problem, likely also malfunctioned on the ship at some point in the original timeline.

In the anti-time past, Captain Picard used his knowledge of his own past to assist Miles O'Brien regarding a problem with the the warp plasma inducers on the USS Enterprise (NCC-1701-D) by providing O'Brien with specifications to bypass the secondary plasma inducer.
