Provision is made for including data for use in the design of feedback amplifiers and control networks, or other circuits in which the knowledge of the transformer amplitude and phase frequency response is needed by the system designer. These transformers are required to transform voltage within specified tolerances of amplitude and phase when operating between specified impedances. Guides to application and test procedures are included. The annexes within this standard contain certain precautions and recommended practices. This standard also pertains to hybrid transformers, primarily used in the telecommunications industry.

          This standard pertains to electronics wide-band transformers transmitting power within a wide band of frequencies covering typically at least one decade in the frequency spectrum. It is not intended to apply to transformers optimized to operate within a narrow band of frequencies. Transformers used in, or in conjunction with, wire line communication facilities serving power stations are excluded due to the special protection requirements involved. Provision is made for including data for use in the design of feedback amplifiers and control networks, or other circuits in which the knowledge of the transformer amplitude and phase frequency response is needed by the system designer. These transformers are required to transform voltage within specified tolerances of amplitude and phase when operating between specified impedances. Guides to application and test procedures are included. The annexes within this standard contain certain precautions and recommended practices. This standard also pertains to hybrid transformers, primarily used in the telecommunications industry. The hybrid transformer is a wide-band transformer used in a manner which makes it part of a capacitance, resistance, and/or inductance network, and it must have characteristics which permit it to match the network for proper overall performance.<br />\n

          New IEEE Standard - Inactive-Withdrawn.<br />\n
          This standard pertains to computer-type pulse transformers. These pulse transformers are characterized by their use of a square loop core material as defined below with normal operation into the saturation flux density regions and with typical operation using a specifically defined current input pulse. These transformers exploit the memory characteristic of square-loop core material that makes the output pulse dependent upon the immediate history of the core flux. This type of transformer is used in shift registers, memory across switches, memory readout circuits, transformer logic matrices, and other storage-type devices. It is not the purpose of this standard to include large-scale memories. Wherever numerical requirements are indicated, they may be considered as recommended values. Appendix I contains a core analysis, transformer equivalent circuit, and definitions of associated terms. Appendix II contains definitions pertaining mainly to characteristic testing of computer-type pulse transformers.<br />\n
          \t\t\t\t<br />\n
          The purpose of this Standard is to provide a common ground of understanding between computer system<br />\n

Power conversion equipment includes items known as inverters, converters, power conditioners, switching power supplies, switched mode power supplies, and the like. These items are mostly devices used to change dc power from one voltage to another, to change dc power to ac, and to change ac power of one frequency to another frequency. This equipment is best described as utilizing transistors, silicon controlled rectifiers (SCRs), or other similar devices that switch power on and off at a high rate in order to achieve the power conversion or regulation desired. Therefore, this standard covers the various transformers and inductors that are used in any of the above mentioned equipment or devices, except for transformers operated directly from the mains.

These tests are designed primarily for transformers and inductors used in all types of electronics applications, but they may apply to the other types of transformers of large apparent-power rating used in the electric power utility industry. Some of the tests described are intended for qualifying a product for a specific application, while others are test practices used widely for manufacturing and customer acceptance testing. Clause 4 is intended to serve as a guide for particular application categories. The tests described in this recommended practice include those most commonly used in the electronics transformer industry: electric strength, resistance, power loss, inductance, impedance, balance, ratio of transformation, and many others used less frequently.

          Pulse transformers for use in electronic equipment are considered. This standard applies to the following transformer types: power output (drivers), impedance matching, interstage coupling, current sensing, and blocking-oscillator transformers.

          This standard pertains to pulse transformers for use in electronic equipment. For the various types of these transformers, the peak power transmitted ranges from a few milliwatts to kilowatts; and the peak voltage transmitted ranges from a few volts to many kilovolts.<br />\n
          These transformers are required to transmit uni polar or bipolar pulses of voltage or current within specified tolerances of amplitude and time when operated between specified impedance. They are typically used as coupling devices in electronic circuits. In blocking oscillators, they are connected to provide positive feedback in the circuit. In radar or similar use, they are used to couple the modulator to a magnetron, a klystron, a traveling-wave tube or a cross-Þeld amplifier load.<br />\n
          Whenever numerical values are indicated in this standard, they may be considered as recommended values. Section 6. describes the preferred transformer test methods and Appendix A contains alternate test methods<br />\n
          The purpose of this standard is to provide a common ground between electronic system engineers and pulse transformer design engineers. This standard does not apply to transformers when used in a wire entrance facility to an electric power station. Neither is it intended to include low-power switching-type pulse transformers. These are covered in IEEE Std 272 1970, IEEE Standard for Computer-Type (Square-Loop) Pulse Transformers. This standard pertains to pulse transformers that transmit peak power that averages from a few milliwatts to those that transmit peak power that averages in the kilowatts. Also, the voltage range is from a few peak volts to many peak kilovolts.

          Pulse transformers for use in electronic equipment are considered. This standard applies to the following transformer types: power output (drivers), impedance matching, interstage coupling, current sensing, and blocking-oscillator transformers. For these transformers, the peak power transmitted ranges from a few milliwatts to many kilowatts, and the peak voltage transmitted ranges from a few volts to many kilovolts. Symbols, performance tests, equivalent circuits, preferred test methods, marking, and service conditions are covered.<br />\n

          This standard pertains to pulse transformers for use in electronic equipment. For the various types of these transformers, the peak power transmitted ranges from a few milliwatts to kilowatts; and the peak voltage transmitted ranges from a few volts to many kilovolts.<br />\n
          These transformers are required to transmit uni polar or bipolar pulses of voltage or current within specified tolerances of amplitude and time when operated between specified impedance. They are typically used as coupling devices in electronic circuits. In blocking oscillators, they are connected to provide positive feedback in the circuit. In radar or similar use, they are used to couple the modulator to a magnetron, a klystron, a traveling-wave tube or a cross-Þeld amplifier load.<br />\n
          Whenever numerical values are indicated in this standard, they may be considered as recommended values. Section 6. describes the preferred transformer test methods and Appendix A contains alternate test methods<br />\n
          The purpose of this standard is to provide a common ground between electronic system engineers and pulse transformer design engineers. This standard does not apply to transformers when used in a wire entrance facility to an electric power station. Neither is it intended to include low-power switching-type pulse transformers. These are covered in IEEE Std 272 1970, IEEE Standard for Computer-Type (Square-Loop) Pulse Transformers. This standard pertains to pulse transformers that transmit peak power that averages from a few milliwatts to those that transmit peak power that averages in the kilowatts. Also, the voltage range is from a few peak volts to many peak kilovolts.

          Transformers have a characteristic that is common to other iron-core devices of causing harmonic currents at voice frequencies to flow in supply circuits to the transformers.

          New IEEE Standard - Superseded.<br />\n
          Procedures for demonstrating the adequacy of new Class 1E transformers, located in a mild environment of a nuclear power generating station, to perform their required safety functions under postulated service conditions are presented. Single- and three-phase transformers rated 601 V to 15,000 V for the highest voltage winding and up to 2500 kVA (self-cooled rating) are covered. Because of the conservative approach used in the development of this standard for new transformers, the end-point criteria cannot be used for in-service transformers.<br />\n

          This standard provides requirements to demonstrate the adequacy of new Class IE transformers, located in a mild environment of a nuclear power generating station as defined in IEEE Std 323-1983 [16]1, to perform their required safety functions under postulated service conditions. This standard applies to single and three phase transformers rated 601 V to 15 000 V for the highest voltage winding and up to 2500 kVA (self-cooled rating).<br />\n
          The purpose of this standard is to provide specific qualification procedures for Class lE transformers to demonstrate their capability to meet the requirements of IEEE Std 323-1983 [16]. The transformer must perform its intended function under all specified service conditions.

          New IEEE Standard - Superseded.<br />\n
          Superseded by IEEE Std C57.12.37-2006 A basis for the electronic reporting of transformer test data on liquid immersed distribu-tion transformers as defined in the ANSI C57.12.2X standards series is provided. The specific setof test data to be reported and the format in which it is to be reported is detailed along with an ex-tended set of data as an option for the user.<br />\n

          Specify what information is required and in what format, when supplying transformer test reports through an electronic, computer readable medium.<br />\n
          Purchasers of transformers are requesting the associated certified test reports in many different formats. It would be in the best interest of all concerned to standardize on the required information and format in an electronic medium because errors could be introduced when a supplier of this informnation must go from one format to anotherre; the terms used in describing data in the test report can be misleading; and a standard format will make the development of test report data generating and data analyzing software easier, more efficient, more accurate and more widely available.
