Epri red book 3rd edition

It prices 8, items in up to 12 grades each, with 50, individual values and 16, auction records covering circulated, Mint State, and Proof coinage. The book is illustrated with 5, images. Named for its distinctive crimson cover, the new Red Book is not. Included in this set up are a string of porcelain disc insulators and three non-ceramic or polymer insulators.

Note the polymer insulator at the far left has corona rings installed, while the two on the right do not. Also, the polymer insulator at the far right has standard line-end hardware installed on it there are bolt ends that are slightly protruding downward , while the other three insulators have corona-free hardware.

Through the use of the DayCor camera, this portion of the demonstration allowed participants the opportunity to see why corona-free hardware is required for transmission lines that are above kV. A tripod in the lower portion of the photo holds a sound level meter to measure the audible noise generated by the corona on the test line and insulators. The test line voltage was raised—from kV to kV—to allow measurements of the audible noise created by corona activity at different voltages.

Participants watch a demonstration of the DayCor camera used to measure corona on a transmission line energized by the DTC 1. The DayCor camera provides a normal video image superimposed with an image that displays a software generated representation of the ultraviolet signature produced by the corona photons.

In the center of this photo the corona camera output is projected onto a screen. Red Flag This Post Please let us know here why this post is inappropriate.
