Front cover of Eaton's Spring and Summer Catalogue 1942. The Eaton's catalogue was a mail-order catalogue published by Eaton's from 1884 to 1976. It was "one of the first to be distributed by a Canadian retail store". [1] The first version of the catalogue was a 32-page booklet handed out at the Industrial Exhibition (now the Canadian National ...
In high-voltage or complex systems, these locks may be part of a trapped-key interlock system to ensure proper sequence of operation. In some designs, the disconnector has the additional ability to earth the isolated circuit thereby providing additional safety. Such an arrangement would apply to circuits that inter-connect power distribution ...
A parts book, parts catalogue or illustrated part catalogue is a book published by a manufacturer which contains the illustrations, part numbers and other relevant data for their products or parts thereof. Parts books were often issued as microfiche, though this has fallen out of favour.
An opto-isolator is a very popular method of isolation in digital circuits. Cross-section of dual in-line package opto-isolators. Relative sizes of LED (red) and sensor (green) are exaggerated. Everlight EL817 phototransistor opto-isolator in DIP-4 package Halo TG110-S050N2RL 10/100BASE-TX Ethernet pulse transformer in SO-16 package.
IEC 60364 Electrical Installations for Buildings is the International Electrotechnical Commission (IEC)'s international standard on electrical installations of buildings.This standard is an attempt to harmonize national wiring standards in an IEC standard and is published in the European Union by CENELEC as "HD 60364".
A 230 V isolation transformer A simple 1:1 isolation transformer with an extra dielectric barrier and an electrostatic shield between primary and secondary. The grounded shield prevents capacitive coupling between primary and secondary windings.
Network isolators are installed as part of a wired Ethernet system as galvanic isolators to reduce the potential for electrical injury and limit the extent of damage due to lightning strikes. Through the applied principle of electromagnetic induction , network data is transmitted across an electrically non-conducting barrier.
