Plasma conduit

A plasma conduit (sometimes referred to as a power conduit) was a vital part of the warp drive and power grids of many spacefaring cultures.

Cleaning plasma conduits was considered to be a menial task, and sometimes delegated as a disciplinary measure. (ENT: "Singularity", "Dead Stop"; VOY: "Q2")

Warp plasma conduit

A warp plasma conduit directed high energy electro-plasma, known as warp plasma or drive plasma, from a warp core, through the ship it was on, to plasma injectors in the nacelle tubes. (TNG: "Phantasms"; ENT: "The Forgotten")

The copper tubing suggested by Lieutenant Barclay to replace the Phoenix's damaged conduit

In 2063, the time-displaced crew of the USS Enterprise-E assisted Zefram Cochrane with making repairs to his warp ship. Since the craft's warp plasma conduit had been damaged, Lieutenant Barclay found a length of copper tubing and suggested that it be used to replace that damaged component. Commander La Forge approved, but noted that it would have to be reinforced with a nanopolymer. (Star Trek: First Contact)

EPS conduit

An EPS conduit takes small amounts of plasma from the warp core or the impulse engines and redirects it throughout the ship for use in powering other systems, such as weapons and navigational deflectors.

In 2154, Trip Tucker warned T'Pol that tying Enterprise NX-01's impulse reactors directly into the deflector array to create a large deflector pulse would rupture every EPS conduit on the ship. (ENT: "Countdown")

The EPS mains of the Galaxy-class USS Enterprise-D were located on deck 13, close to cargo bay 4. (TNG: "Schisms")

In 2129, the plasma conduits on a Kantare supply ship were overloaded by an ion storm, causing it to crash land on an unidentified planet. (ENT: "Oasis")

In 2153, a plasma conduit rupture aboard a Xindi-Primate ship was faked by Archer's crew to explain the Xindi crew's loss of consciousness, when in fact they'd had their memories wiped in an effort to extract information. (ENT: "Stratagem")

In November 2154, Hoshi Sato feigned annoyance about "noisy" plasma conduits that ran across the ceiling in her quarters aboard Enterprise NX-01. This was done in order to prepare Captain Archer for his dealings with Ambassador Gral, whose people thrived on arguments. (ENT: "Babel One")

The plasma conduit on a Bajoran raider piloted by Kira Nerys and Jadzia Dax in 2370 suffered damage in battle, forcing them to eject the associated plasma tank. (DS9: "The Siege")

Later that year, Deanna Troi candidly admitted to Will Riker she had trouble "telling the difference between a plasma conduit and a phase inducer." (TNG: "Thine Own Self")

An unshielded warp plasma conduit could interfere with combadges. (DS9: "For the Uniform")

By running a plasma conduit through the USS Defiant's primary phaser coupling, the ship's phaser power was almost doubled.(DS9: "Defiant")

A Bajoran transport carrying Kai Winn Adami and Vedek Bareil Antos to Deep Space 9 in 2371 had a molecular fracture in one of its plasma conduits. The conduit collapsed, destroying the entire relay system. (DS9: "Life Support")

In early 2371, Joseph Carey and B'Elanna Torres had an argument over realigning the USS Voyager's lateral plasma conduit. This action would have resulted in an overload. (VOY: "Parallax")

After the power supply grid on Deep Space 9 was overloaded in 2371, it caused a power surge that blew out a plasma conduit, blocking a Jefferies tube with debris. (DS9: "Civil Defense")

Also in 2371, a phase variance in plasma conduit 3 inhibited Voyager's thrusters. This was caused by Torres, Seska and Carey making an illicit attempt to use a spatial trajector. (VOY: "Prime Factors")

Later that year, the warp plasma conduit was one of several areas where a Founder planted a device that gave it access to all of the Defiant's shipboard systems. (DS9: "The Adversary")

In 2372, Tom Paris, affected by hyper-evolution, used a phaser on Voyager's port plasma conduit and thereby knocked out power throughout the ship. (VOY: "Threshold")

Lon Suder tried to use an EPS conduit to dispose of the body of Crewman Darwin after he murdered him, but Suder damaged the conduit while putting the body inside and, as a result, the remains were only severely burned instead. (VOY: "Meld")

A blown plasma conduit was one of several reasons proposed by Kira Nerys for an explosion witnessed by herself and Miles O'Brien. (DS9: "Sons of Mogh")

When Tierna blew himself up aboard Voyager in 2372, he simultaneously destroyed a primary plasma conduit. (VOY: "Basics, Part I")

In 2373, plasma conduit G6 blew in engineering aboard Voyager during a battle between that ship and the Nerada. (VOY: "Favorite Son")

Soon after, Torres attributed an unspecified malfunction to a plasma conduit, while Paris correctly suspected the problem lay with the anodyne relays. (VOY: "Distant Origin")

In 2374, a plasma conduit exploded aboard the USS Honshu when the ship was attacked by Cardassian destroyers, knocking out Benjamin Sisko. (DS9: "Waltz")

Also that year, malfunctioning bioneural gel packs on Voyager caused false readings to be fed to the sensors, which therefore incorrectly showed plasma conduits were rupturing on decks seven and thirteen. (VOY: "One")

Soon after, Captain Kathryn Janeway listed a plasma conduit amongst the things a replicator was capable of creating, upon instructions. (VOY: "Latent Image")

Voyager salvaged at least a dozen plasma conduits from a Borg vessel in 2375. (VOY: "Dark Frontier")

Later that year, Harry Kim untruthfully claimed to Paris to have been checking the plasma conduits in section 22 of the Varro generational ship, when he had in fact been with Derran Tal. (VOY: "The Disease")

In 2376, when Voyager was hit by a neutronic wavefront, a plasma conduit ruptured on deck nine. (VOY: "Fair Haven")

In 2377, Chakotay asked The Doctor, functioning as the ECH, to repair ruptured plasma conduits aboard Voyager, but The Doctor felt he'd do better to remain in command. (VOY: "Workforce")
