IEEE/ANSI C57.12.25-1990

This standard covers certain electrical, dimensional, and mechanical characteristics, and takes into consideration certain safety features of single-phase, 60-Hz, mineral-oil-immersed, self-cooled, pad-mounted, compartmental-type distribution transformers with separable insulated high-voltage connectors. These transformers are rated 167 kVA and smaller, with high voltages of 34500 GrdY/19 920 volts and below for operation between one phase and grounded neutral, and low voltages of 240/120 volts. These transformers are generally used for step-down purposes from an underground primary cable supply.

Superseded **Revision of 802.1D-1990 edition (aka ISO/IEC 10038). 802.1D incorporates P802.1p and P802.12e. It also incorporates and supersedes published standards 802.1j and 802.6k. Superseded by 802.1D-2004. The concept of Media Access Control (MAC) Bridging, introduced in the 1993 edition ofthis standard, has been expanded to define additional capabilities in Bridged LANs aimed at providing for expedited traffic capabilities, to support the transmission of time-critical information in a LAN environment; and providing filtering services that support the dynamic use of Group MAC Addresses in a LAN environment.


This guide provides engineering principles, practices, and guidelines for the selection and application of fast response systems of customer-side loads in modern power grids. It considers the impact of increasing the penetration of renewable energy sources in power systems. The definitions, classification and characteristics of rapid load response resources are elaborated in this guide, such as active response loads, interruptible loads and energy storage. It provides complementary approaches for mitigating frequency stability issues of bulk power systems and microgrids, as well as absorbing renewable power. Function architecture, control strategy, and system implementation for quick response systems of customer-side loads are…

IEEE/IEC 63195-1-2022

This International Standard specifies protocols and test procedures for the reproducible and conservative measurement of the power density (PD) assuming incident to the head or the body by radio-frequency (RF) transmitting devices, with a defined uncertainty. The protocols and procedures apply for a significant majority of people including children during the use of hand-held and body-worn wireless communication devices. These devices may feature single or multiple transmitters or antennas, and may be operated with their radiating part(s) at distances up to 200 mm from a human head or body. This standard can be employed to evaluate PD compliance of different…


This standard develops a set of common functionality for the family of IEEE 1451 smart transducer interface standards. This functionality is independent of the physical communications media. It includes the common transducer services required to control and manage smart transducers and Transducer Electronic Data Sheet (TEDS) formats. It defines a set of implementation-independent application programming interfaces (API). This project does not specify signal conditioning and conversion, physical media, or how the TEDS data are used in applications.


This project establishes a standard for wireless communication methods and data format for transducers (sensors and actuators). The standard defines a TEDS based on the IEEE 1451 concept and protocols to access TEDS and transducer data. It adopts necessary wireless interfaces and protocols to facilitate the use of technically differentiated, existing wireless technology solutions. It does not specify transducer design, signal conditioning, wireless system physical design or use, or use of TEDS.
