Data interchange and standard software services for test and diagnostic environments are defined by Artificial Intelligence Exchange and Service Tie to All Test Environments (AIESTATE). The purpose of AI-ESTATE is to standardize interfaces for functional elements of an intelligent diagnostic reasoner and representations of diagnostic knowledge and data for use by such diagnostic reasoners. Formal information models are defined to form the basis for a format to facilitate exchange of persistent diagnostic information between two reasoners and also to provide a formal typing system for diagnostic services. The services to control a diagnostic reasoned are defined by this standard.

Definitions and usage of terms used in the measurement and analysis of corona and field effects of overhead power lines are presented in this standard. Correlation between measurements from equipment to standard terms is defined. Weather conditions such as rain, snow, fog, and drizzle are defined and their measurement standards discussed. The intent is to assist in correlating standard terms found in literature and requirements to standard engineering practice.

General recommendations for the operation, loading, and maintenance of synchronoushydro-generators and generator/motors are covered. This guide does not apply to synchronousmachines having cylindrical rotors. In this guide, the term hydro-generator is used to describe asynchronous machine coupled to a hydraulic turbine or pump-turbine. This guide is not intended toapply in any way to the prime mover.

Methods for defining the dc load and for sizing a lead-acid battery to supply that load for stationary battery applications in float service are described in this recommended practice. Some factors relating to cell selection are provided for consideration. Installation, maintenance, qualification, testing procedures, and consideration of battery types other than lead-acid are beyond the scope of this recommended practice. Design of the dc system and sizing of the battery charger(s) are also beyond the scope of this recommended practice.

Recommended design practices and procedures for storage, location, mounting, ventilation, instrumentation, preassembly, assembly, and charging of vented lead-acid batteries are provided. Required safety practices are also included. These recommended practices are applicable to all stationary applications. Specific applications, such as emergency lighting units, semiportable equipment, and alternate energy applications, may have other appropriate practices and are beyond the scope of this recommended practice.

Maintenance, test schedules, and testing procedures that can be used to optimize the life and performance of permanently installed, vented lead-acid storage batteries used for standby service are provided. Guidance to determine when batteries should be replaced is also provided. This recommended practice is applicable to standby service stationary applications where a charger maintains the battery fully charged and supplies the dc loads.

Uniform procedures for the measurement of radio noise generated by corona from overhead power lines and substations are established in this standard. Measurement procedures in this standard are also valid for other power-line noise sources such as gaps and harmonics; however, most of the precautionary information, analysis, and data plotting techniques were written and developed primarily for corona discharges. The procedures are not valid for measuring transient radio noise sources that occur during breaker or disconnect switching operations. The procedures apply in the frequency range of 0.010 MHz to 1000 MHz; however, the emphasis is on the standard amplitude-modulation broadcasting (0.535 MHz to 1.605 MHz) and television broadcasting (54 MHz to 72 MHz, 76 MHz to 88 MHz, 174 MHz to 216 MHz, and 470 MHz to 698 MHz) bands. This standard is applicable to both ac and dc transmission lines and substations.

The recommended practices and procedures for direct voltage acceptance and maintenance testing of shielded, laminated, dielectric-insulated power cable systems rated 5 kV to 500 kV are presented in this guide. It applies to all types of laminated power cable systems such as paper insulated, lead covered, pipe-type, and pressurized cables that are intended for the transmission or distribution of ac electric power. The tabulated test levels assume that the cable systems have an effectively grounded neutral system or a grounded metallic shield.

In today’s digital age, technology has a firm grasp on practically every aspect of human life, consequently there is growing cross-sector demand to help individuals build digital competencies such as digital literacy, digital skills, and digital readiness. However, there is no universally accepted meaning of terms like “digital literacy,” “digital skills,” or “digital readiness,” which can lead to difficulty coordinating efforts to improve digital competencies worldwide. Digital Intelligence (DQ) was developed to encompass a comprehensive set of technical, cognitive, meta-cognitive, and socio-emotional competencies, which are grounded in universal moral values and enable individuals to face the challenges of digital life and adapt to its demands. The DQ Framework is comprised of 8 areas of digital life--identity, use, safety, security, emotional intelligence, literacy, communication, and rights--across 3 levels of experience--citizenship, creativity, and competitiveness. The objective of this standard is to establish a DQ global standard that encompasses a common framework to ensure that digital competency building efforts are coordinated globally. It includes a common set of definitions, language, and understanding of digital literacy, skills, and readiness that can be adopted by all stakeholders worldwide, including national governments, the educational industry, the technology industry, international agencies, private companies, and society as a whole.

The aim of this recommended practice is to establish a protocol for the measurement of partial discharges using ac voltages and VHF/UHF electromagnetic sensors, for quality control during routine tests on factory and pre-molded joints of high-voltage direct-current (HVDC) extruded cable systems having voltage ratings up to 800 kV. The various steps of the protocol for the measurement of partial discharges in such cables are carefully described. Details are given about the procedure for a sensor performance check, test setup preparation, and success criteria. The ultimate goal of this recommended practice is not verifying the compliance with any maximum acceptable limit of partial discharge amplitude, but rather focusing on the whole phenomenon of partial discharges, in order to assess whether critical partial discharges are present in the tested object (either a factory joint or a pre-molded joint of a HVDC extruded cable system). “Critical partial discharge” is used here to mean a discharge within the insulation of the object under test, excluding all external discharges that can be present during the ac voltage test, (e.g., corona discharges due to HV electrodes, conducting leads related to the test setup).
