Intermediate metal conduit (IMC) is a steel tubing heavier than EMT but lighter than RMC. It may be threaded. Electrical metallic tubing (EMT), sometimes called thin-wall, is commonly used instead of galvanized rigid conduit (GRC), as it is less costly and lighter than GRC. EMT itself is not threaded, but can be used with threaded fittings that ...
The original and most common meaning is a hollow conductive metal pipe used to carry high frequency radio waves, particularly microwaves. [1] Dielectric waveguides are used at higher radio frequencies, and transparent dielectric waveguides and optical fibers serve as waveguides for light.
Electromagnetic compatibility (EMC) is the ability of electrical equipment and systems to function acceptably in their electromagnetic environment, by limiting the unintentional generation, propagation and reception of electromagnetic energy which may cause unwanted effects such as electromagnetic interference (EMI) or even physical damage to ...
The EMTP recoding project started in 1998 by J. Mahseredjian. J. Mahseredjian worked later with a small team of developers, including mainly S. Dennetière, O. Saad, C. Dewhurst and Laurent Dubé, to deliver the new commercial version of EMTP, in 2003. It was then released under the version named EMTP-RV, RV meaning restructured version.
power engineering That part of electrical engineering that deals with the generation, distribution and consumption of electrical power. power-factor correction Apparatus intended to bring the power factor of some load closer to 1. power factor The ratio of apparent power flowing to a load divided by the real power. power-flow study
An order from the engineering department (to be followed by the production department or vendor) overriding/superseding a detail on the drawing, which gets superseded with revised information. Also called by various other names, such as engineering change order (ECO), engineering change notice (ECN), drawing change notice (DCN), and so on.
The material with which a pipe is manufactured often forms as the basis for choosing any pipe. Materials that are used for manufacturing pipes include: Carbon steel; ASTM A252 Spec Grade 1, Grade 2, Grade 3 Steel Pile Pipe; Plastic piping, e.g. HDPE pipe, PE-X pipe, PP-R pipe or LDPE pipe. [11] Low temperature service carbon steel; Stainless steel
Penetrants, or penetrating items, are the mechanical, electrical or structural items that pass through an opening in a wall or floor, such as pipes, electrical conduits, ducting, electrical cables and cable trays, or structural steel beams and columns. When these items pierce a wall or floor assembly, they create a space between the penetrant ...
