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… read more 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. read less

This project defines a serial, full-duplex, asynchronous, 9-pin DTE communications port that follows EIA 574 and related standards. Portions of several standards will be referenced along with specific extensions applying to programmable instruments. The resulting draft will apply to point-to-point instrument systems composed of a measurement, stimulus or interconnect device and an instrumentation controller. It may also apply to certain devices outside the scope of the instrument system… read more environment. The document will cover mechanical, electrical and functional requirements of the interface. read less

To assist in providing a uniform method for calculating and measuuring torque pulsations which occur during starting of synchronous motors. Synchronous motors as discussed in this guide specifically refer to salient-pole type motors with wound main field circuits with either a continuous or interrupted amortisseur cage/ In modern installations, direct current is applied to the main field by means of slip rings from a static exciter or by a rotating brushless excitation system to establish synchronous operation.

This document provides a set of standard verification tasks for processor-based equipment used in safety critical applications on rail and transit systems. The scope of the standard shall encompass and be limited to processes which verify the level of safety achieved in the implementation of safety critical functions which are required to be fail-safe. It does not address quality assurance or validation processes which also affect the level of overall system safety achieved.

This recommended practice applies to utility-interconnected PV power systems operating in parallel with the utility and utilizing static (solid-state) inverters for the conversion of direct current (dc) to alternating current (ac). (This recommended practice does not apply to systems utilizing rotating inverters.) This recommended practice describes specific recommendations for "small" systems, rated at 10 kW or less, such as may be utilized on individual residences. These recommendations will provide greater standardization for these smaller systems, thereby reducing the engineering and design burden on both the PV system installer and the interconnecting utility. "Intermediate" applications, ranging from over 10 kW up to 500 kW, follow the same general guidelines as small systems. Options to have adjustable setpoints or other custom features may be required by the inter-connecting utility, depending on the impact of the PV system on the portion of the utility system to which it is interconnected. "Large" systems, greater than 500 kW, may combine various standardized features as well as custom requirements, depending on the impact of the PV system on the portion of the utility system to which it is interconnected. A greater degree of custom engineering of the utility interface is to be expected as the size of the PV system grows in relation to utility system capacity
