Metal-oxide surge arresters designed to repeatedly limit the voltage surges on 48 Hz to 62 Hz power circuits (>1000 V) by passing surge discharge current and automatically limiting the flow…
This document provides definitions of electric power to quantify the flow of electrical energy in single-phase and three-phase circuits under sinusoidal, non-sinusoidal, balanced, and unbalanced conditions.
This guide is primarily concerned with outdoor ac substations, either conventional or gas-insulated. These include distribution, transmission, and generating plant substations. With proper caution, the methods described herein are also…
Guidance for the power system user in applying, installing and operating digital communication channels for the purpose of protective relaying is provided in this guide.
The use of some electrical equipment attached to typical power systems creates voltage quality concerns. There is an increasing awareness that some equipment is not designed to withstand the surges,…
This standard defines a protocol and procedures for the transport of timing over bridged and virtual bridged local area networks. It includes the transport of synchronized time, the selection of…
The main emphasis of this recommended practice is the engineering design of optical fiber communication facilities serving, or connected to, electric supply locations. This document includes methods for providing telecommunication…
Ethernet local area network operation is specified for selected speeds of operation from 1 Mb/s to 10 Gb/s using a common media access control (MAC) specification, management information base (MIB),…
Electromagnetic compatibility (EMC) criteria and consensus test and measurements procedures for broadband over power line (BPL) communication equipment and installations are presented. Existing national and international standards for BPL equipment…
