Tie line (telephony), a circuit between two telephone exchanges. Tie line (electrical grid) , an electrical circuit connecting balancing authorities. Tie line , an isothermal line through a two-phase region on a phase diagram.
Because of the presence of a neutral fuse, and in the event that it blew, the neutral conductor could not be relied on to remain near ground potential; and, in fact, could be at full line potential (via transmission of voltage through a switched-on light bulb, for example). [5] Modern electrical codes generally do not require a neutral fuse.
The uni knot is widely used for attaching hooks, rings and swivels to the end of the line [7] and it is also used for joining two fishing lines together. [8] The bend form of the uni knot (for joining two lines) is not a noose; rather it is akin to a multiple fisherman's knot with the two opposing knotted parts arranged in the manner of uni knots.
An interconnector (also known as a DC tie in the USA [1]) is a structure which enables high voltage DC electricity to flow between electrical grids. An electrical interconnector allows electricity to flow between separate AC networks, or to link synchronous grids .
A typical one-line diagram with annotated power flows. Red boxes represent circuit breakers, grey lines represent three-phase bus and interconnecting conductors, the orange circle represents an electric generator, the green spiral is an inductor, and the three overlapping blue circles represent a double-wound transformer with a tertiary winding.
A tie line, also known as a tie trunk, is a telecommunication circuit between two telephone exchanges or two extensions of a private telephone system. [1] [2]
LSM is used mainly in the construction industry to schedule resources in repetitive activities commonly found in highway, pipeline, high-rise building and rail construction projects. These projects are called repetitive or linear projects.
A spoolbase is a shore-based facility used to facilitate continuous pipe laying for offshore oil and gas production. [1] The facility allows the welding of single or double joints (40' or 80') of steel pipe of 4" to 18" diameter, into predetermined lengths for spooling onto a reel lay vessel.
