| Abstract | The accurate and comparable measurement of voltages and currents in the frequency range of 2 kHz to 150 kHz is a basic requirement for the assessment of emission limits, compatibility levels and immunity limits and therefore important for a consistent standardization framework. Currently a measurement method for frequencies of 2 kHz to 9 kHz exists in the informative annex of IEC 61000-4-7, which could be extended in application to 150 kHz. The committee draft for vote of IEC 61000-4-30 Ed.3 proposes a new method for the frequency range of 9 kHz to 150 kHz, which is different from the aforementioned one. This paper identifies parameters with impact on measurement results and compares both methods based on multiple test signals, which are derived from lab measurements of different equipment and field measurements in low voltage networks. The comparison is carried out regarding the necessity of filters, chosen bandwidth, impact of band boundaries and methods for aggregation in time. The results show that the two measurement methods have individual benefits and drawbacks. Finally, the paper proposes several approaches to combine the advantages of both methods. |

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.
