| Abstract | The increasing of sensitive electrical equipment in our technologies is the biggest issues to power line system. The quality of electrical power supply becomes more concern to customers or electric users. Power quality signals will affect manufacturing process, failure of equipment and economic losses. This paper presents the development of power quality signals monitoring system using linear time-frequency distribution (TFD) which is spectrogram. The TFD is used to represent the signals in time-frequency representation (TFR) and is very appropriate to analyze power quality signals that have magnitude and frequency variations. Parameters of signal such as instantaneous of root means square (RMS) voltage, fundamental RMS voltage, total waveform distortion (TWD), total harmonic distortion (THD) and total non-harmonic distortion (TnHD) are estimated from the TFR to identify the signal characteristics. Standard power line measurements are also calculated from voltage and current such as RMS voltage and current, real power, apparent power, reactive power, frequency and power factor. The developed system also shows high accuracy monitoring system that presents very low absolute percentage error (APE) measurements and is suitable for power quality monitoring purpose. |

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.
