IEEE 356-2020

Measurements of the electrical properties of naturally occurring solids are covered in the scope of this guide. Not covered are methods that rely on mapping earth structure anomalies unless directly related to electrical properties. Coverage of numerical methods for forward/inverse modeling is limited.

IEEE 149-2021

The recommended practices for the measurement of antenna transmitting and receiving properties are presented. Throughout this standard it is assumed that the antenna to be measured can be treated as a passive, linear, and reciprocal device. A fundamental property of any antenna is its radiation pattern. The measurement of radiation patterns in an antenna test facility is discussed. The design of antenna test facilities is described along with instrumentation requirements for the proper operation of the antenna facility, directions for the evaluation of an (existing) range, and the operation of ranges is discussed. References are provided that are illustrative of…

The process of the measurement of the radar cross section of objects using a test range is described in this recommended practice. The term radar cross section (RCS) is defined, and the characteristics of different types of test ranges are given. The responsibilities of the test range operators are shown to involve test and calibration of the measurement range systems and to take the measurements accurately. Techniques are described for each stage of this process.

IEEE 211-2018

Terms and definitions used in the context of electromagnetic wave propagation relating to the fields of telecommunications, remote sensing, radio astronomy, optical waves, plasma waves, the ionosphere, the magnetosphere, and magnetohydrodynamic, acoustic, and electrostatic waves are supplied.

IEEE 149-1965

This Test Procedure, which supersedes the previous issue, Standards on Antennas--Methods of Testing 48 I R E 2S2, is concerned with measurements of the properties which characterize antennas. In Section 1.2, symbols and units to be used in this test Procedure are defined. The effect of the environment on the antenna and its characteristics is discussed in Section 1.3, and certain precautions to be taken during the measurements are suggested. In Section 1.4, the usefulness of the reciprocity theorem in antenna measurements is cited, along with examples of situations in which this theorem does not apply.

AIEE 21-1942

These standards specifically cover the following types of bushings: ( o ) Outdoor bushings for large apparatus. ( 6 ) Cover type bushings for small apparatus. ( c ) Indoor bushings for all types of apparatus except dry type instrument transformers, air-blast transformers, dry type regulators, and circuit breakers rated below 5,000 volts, and non-oil tight oil circuit breakers rated 50,000 kva or less. These standards are not intended to apply to wall bushings, cable potheads, nor insulators for back connected disconnecting switches, although many of the principles may be applicable. The bushing requirements as specified in these standards apply…

IEEE/ASA 21-1964

This Standard covers the following: (1) Electrical requirements for outdoor power apparatus bushings having basic impulse insulation levels 110 through 1300 kilovolts. (2) Mechanical requirements for the outdoor power apparatus bushings listed in Table 7.4. (3) Dimensions of the outdoor power transformer and alternating-current power circuit breaker apparatus bushings listed in Tables 7.1(a), 7.1(b), and 7.1(c). 1.2 This Standard does not apply to bushings for indoor apparatus, dry type instrument transformers, air-blast transformers, dry type regulators, oil-less and oil-poor apparatus, roof, floor, wall and generator bushings, potheads, distribution type circuit breakers and back-connected switch insulators. 1.3 Bushing requirements as set…
