How to calculate a 90-degree bend in the pigtail channel
The calculation formula is: BA = (Angle × π/180) × (Radius + K-factor × Thickness) Where Angle: is the bending angle in degrees (for a 90-degree bend, it is 90°). Then input the bend angle to get the arc length, bend allowance and bend deduction. With this bend allowance calculator, you will learn how to calculate the length of a sheet metal bend so you can optimally create metal bendings without a bend allowance chart. It works as a bend deduction calculator too! This tool calculates bend allowance/deduction based on material thickness.

Design of 110kV Relay Protection Communication Channel
This guide was prepared by the WECC Telecommunications and Relay work groups. In this paper, the main electric wiring mode of 110kV substation is selected, the structure of substation is determined, and then the main wiring diagram is drawn. According to the design and load of the primary electrical connection, select the maximum and minimum operating modes to calculate the. The equipment manufactured shal for trouble free operation of the equipment specified in this specif acturing shall be such that. This document supplements PJM Manual 07 which contains the minimum design standards and requirements for the protection systems associated with the bulk power facilities within PJM.

Relay Protection Transmission Channel Technology
Transmission line protection is the coordinated use of protective relays, instrument transformers, circuit breakers, communication channels, and backup logic to detect faults on high-voltage lines and isolate the affected section. Abstract: Information on the concepts of protection of ac transmission lines is presented in this guide. They offer the user a fully programmable system for Direct Transfer Trip, Permissive Transfer Trip, Blocking, Unblocking and Phase Comparison applications. Transmission lines act like the arteries in the human circulatory system, moving electrical power from were it is produced by generators to where it is consumed at load centers.

How to measure fiber optic channel attenuation
Why is low attenuation important for optical communication systems? Low attenuation keeps your signal. Attenuation -- the dB-per-kilometer loss of light traveling through the glass -- is the fundamental property of fiber. Three methods exist for measuring it: cutback (the reference standard), insertion loss (the field standard), and OTDR (the diagnostic tool). The most fundamental parameter for optical fiber is geometry, since the dimensions of the fiber determine its ability to be spliced and terminated to other fibers.
