Abstract | The number of distributed energy sources (DER), the huge increase of loads with switching supplies and the massive use of compact saving lamps brings the need to measure and evaluate voltage and current up to 9kHz. Annex B of the latest update of the IEC 61000-4-7:2002/A1:2008 unifies the length of the basic time window for the evaluation of signal components up to 2kHz and for the evaluation of signal components in the range of 2kHz–9kHz. This fact, together with latest measurement technologies, allows the simultaneous evaluation of signal components in the entire range of 50Hz–9kHz, even for very small amplitudes of frequency components. This paper analyzes and describes the technical problems to be solved in order to meet the requirements of IEC 61000-4-7:2002/A1:2008. The paper presents the results of measurements performed on different loads with expected significant signal components in the frequency range of 2kHz–9kHz, such as PC power supply. Compatible levels for frequency components in the range of 2–9kHz are discussed. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
