Warp plasma regulator
An assimilated Tarkalean attempts to overload the warp plasma regulators
A warp plasma regulator was a component used to regulate warp plasma in the warp drive of a starship.
In 2153, two Tarkaleans who had been assimilated by the Borg attempted to overload some of Enterprise NX-01's warp plasma regulators in an effort to destroy the ship. To stop them, Captain Jonathan Archer ordered an outer hatch opened, causing a decompression which blew the Tarkaleans into open space. (ENT: "Regeneration")
