Program production, as a skill and an applied art, historically began when photographic cinematography followed the Greek theater, and from there, expanded to embrace television and video. Now essential further contributions and modulations are recognized from computer graphics, data processing, gra...
This standard applies to surge-protective devices designed for repeated limiting of voltage surges on 50 Hz or 60 Hz power circuits by passing surge discharge current and subsequently automatically interrupting the flow of follow current. This standard applies to devices for separate mounting and to...
This document supersedes IEEE Std 28-1972 (ANSI C62.1-1971) and revises many portions ofthe previous edition. Three new significant design tests have been added to determine:(1) The highest 1.2 x 50 standard impulse which the surge arrester will allow without sparkover(2) The effect of external cont...
The issuance of this document to supersede IEEE Std 28-1967 (ANSI C62.1-1967) revises manyportions of the standard and adds two significant design tests, namely, switching-surge sparkovercharacteris
The current issue of this Standard is a revision of the previous issue C62.1-1957 to change many of the definitions, to add a new definition titled "Virtual Duration of Wave Front" which changes the method of measuring time to crest value, to eliminate the word "type" from arrester classification de...
The standards in this section shall apply to all types of lightning arresters designed for the protection of alternating-current power circuits.
