This standard covers certain electrical, dimensional, and mechanical characteristics and safety requirements of single-phase, 60-Hz, liquid-filled, self-cooled, pad-mounted, compartmental-type distribution transformers. These transformers are rated 250 kVA and smaller with the high voltages of 34 500 GrdY/19 920 V and below for operation between one phase and grounded neutral and low voltage of 480/240 V and below. These transformers are generally used for step-down purposes from an underground… read more primary cable supply. This standard covers the connector, bushing, and terminal arrangements for radial or loop feed systems. This standard does not cover all electrical and mechanical requirements of accessory devices that may be supplied with the transformer. read less

This recommended practice covers the voltage endurance testing of form-wound bars and coils for use in large rotating machine stator windings. Such testing is defined for machines with a nominal voltage rating up to 30 000 V. These tests are to be applied at 50 Hz or 60 Hz and may be done at either room temperature or elevated temperature. (Testing at 50 Hz or 60 Hz may yield different times to failure for comparable samples.) The specimen to be tested should be representative of the bars or… read more coils used in the machine, and should include the complete insulated bar and external grading construction that the machine winding would have. Special features different than those used in the machine should not be added to the test specimens. read less

Within the context of the ISO/IEEE 11073 family of standards for device communication, this standard establishes a normative definition of communication between personal telehealth urine analyzer devices and managers (e.g., cell phones, personal computers, personal health appliances, set-top boxes) in a manner that enables plug-and-play interoperability. It leverages appropriate portions of existing standards including ISO/IEEE 11073 terminology, information models, application profile… read more standards, and transport standards. It specifies the use of specific term codes, formats, and behaviors in telehealth environments restricting optionality in base frameworks in favor of interoperability. This standard defines a common core of communication functionality for personal telehealth urine analyzers. read less

This guide is intended for fiber optic cables designed for use in power generating stations and industrial facilities, in both the outside plant environment and indoor applications--the latter with adequate consideration for requirements of the National Electrical Code (NEC). It is not the intention of this guide to establish requirements for cables designed for installation in a high voltage environment, such as optical ground wire and all-dielectric, self-supporting. These applications are… read more covered by other IEEE documents (IEEE Std 1138(TM) and IEEE Std 1222(TM). read less
