The application guide for relay protection of squirrel-cage and wound-rotor induction motors presents a review of the generally accepted forms of motor protection and summarizes the use of relays and devices, singly and in combination, to enable the reader to properly select the necessary equipment to obtain adequate motor protection. The Guide is prepared primarily for the protection of three-phase integral-horsepower motors and refers to single- or two-phase motors only in special instances… read more and only where specifically indicated. It is especially useful where the motor installation is sufficiently important, due to either its size or the consequences of motor malfunction, to justify specific design of the protective system. It also provides the information necessary to judge whether there are safety or economic reasons for such a specific design. This Guide is not a Standard and does not purport to detail the protective requirements of all motors in every situation. Its recommendation is of a general nature designed to cover the usual or typical motor installation. Sufficient background of material on objectives, application, and setting philosophy is presented, however, to enable the reader to evaluate the need for various forms of protection and to select and properly apply suitable protective equipment for most situations. read less

The reliable performance of oil in an insulation system depends upon certain basic oil characteristics which can affect overall apparatus characteristics. Such oil characteristics are integral parts of the equipment design for which the manufacturer has final responsibility. The reliable operation of the equipment in service for which the electric power producer has final responsibility also depends on maintaining certain basic oil characteristics. Adherence to the recommended oil… read more characteristics will assist in obtaining the desired equipment characteristics. Other tests or verification of the integrity of the insulation system are often necessary and required. read less

This standard applies to both wireless communications devices (WDs) and hearing aids. It sets forth uniform methods of measurement and parametric requirements for the electromagnetic and operational compatibility of hearing aids and WDs, including cellular phones, personal communications service (PCS), and voice-over-Internet-protocol (VoIP) devices, operating in the range of 614 MHz to 6 GHz. TIA-1083, Telecommunications Communications Products Handset Magnetic Measurement Procedures and… read more Performance Requirements [B87], has become the recognized standard for measurement procedures and performance requirements for handset-generated audio band magnetic noise of wireline communications devices, including cordless telephones (cordless handsets with wireline-connected base units). Ongoing communications between the TIA TR-41.3.14 accessibility working group and ANSI C63.19 working group have been maintained with the objective of harmonizing the two standards to the maximum extent possible. This standard is intended to apply to all types of hearing aids with acoustic output, including, as examples, behind-the-ear (BTE), in-the-ear (ITE), in-the-canal (ITC), completely-in-the-canal (CIC) types, and receiver-in-the-canal (RIC). Test methods are provided for acoustic (microphone input) mode and tele-coil (T-Coil) hearing aid modes of operation. Users of this standard are cautioned to maintain the field strength called for in various places in the document within the limits for radio-frequency (RF) safety specified in IEEE Std C95.1(TM) [B65]. read less

The purpose of this document is to provide guidelines for the use of automatic test equipment (ATE) for the measurement of electromagnetic emissions of electronic, electrical, and electro-mechanical equipment. It is intended to be a companion document to ANSI C63.2-19961 and ANSI C63.4-2003 for making accurate and repeatable automated emissions measurements from 9 kHz to 1 GHz according to commercial Electromagnetic Interference (EMI) regulations. As such, it addresses automated measurement… read more processes, automatic test equipment, and measurement integrity aspects. Furthermore, the importance of a test plan will be outlined. Although intended for automatic testing, these guidelines also apply to semiautomatic measurements where only parts of a test may be automated. read less

This consensus standard specifies methods, instrumentation, and facilities requirements for the compliance testing radio transmitters designed to operate in a licensed radio service. It does not include limits or licensing requirements. Tests methods are provided for measurement of radiated and conducted emissions, RF output power, out-of-band emissions, frequency stability, and other regulatory requirements for a variety of devices, as described in this standard. This standard does not consider test methods for requirements specific to maritime and aviation transmitters, ground based radars, satellite communication equipment, fixed microwave equipment, and broadcast transmitters. The latter equipment types may be covered in future revisions of this standard. In addition, this standard does not include evaluation methods for transmitters subject to regulatory requirements concerning human exposure to RF energy; RF exposure conformity assessment methods are given in other standards, e.g., IEEE Std 1528(TM)-2013 [B41].2 Other documents covering a limited number of the test procedures included in this standard are available and may be used at the discretion of the regulatory authority, e.g., IEEE Std 377(TM)-1980 [B36], TIA-102.CAAA-D [B62], TIA 603-D-2010 [B63].

This standard includes procedures for evaluating the compliance of lighting devices with applicable electromagnetic compatibility (EMC) requirements. Test procedures for radiated field strength and conducted disturbance measurements are included, with reference to established standards, where applicable. This standard covers measurement methodologies, but is not intended to describe regulatory limits. Some regulatory agencies classify lighting devices either as Industrial, Scientific and… read more Medical (ISM) equipment or as digital equipment, depending on its technology. However, if the lighting device includes any wireless modules (intentional radiator, e.g., IEEE 802.11), that portion of the lighting device is usually classified as radio apparatus. This standard includes methods for evaluating the compliance of the lighting device, excluding its radio apparatus portion (if any), with the applicable EMC limits, as specified by the purchasing agency or regulatory authority. Compliance evaluation procedures for radio apparatus are usually subject to other testing procedures; e.g., ANSI C63.10 [B1], ANSI C63.26 [B2], and/or additional or other applicable requirements, as specified by the purchasing agency or regulatory authority. This standard does not cover the testing of other types of ISM equipment, incidental or un-intentional radiators. read less
