| Abstract | In this paper, the influence of the frequency response of coupling capacitor voltage transformers (CCVT) on traveling wave-based fault locators is analyzed, highlighting the benefits of the CCVT secondary voltage compensation when only voltage measurements are available. In order to do so, the frequency response of a well-known 230 kV CCVT model is evaluated and a digital compensator is proposed. Several fault scenarios in a 230 kV power system were simulated via Alternative Transients Program (ATP). In each case, the fault point was estimated using a two-terminal traveling wave-based fault location algorithm, considering as inputs the primary voltages, secondary voltages and secondary voltages corrected by the proposed digital compensator. For a more thorough evaluation, the analyzed fault location method was implemented using two different transient detection algorithms available in the literature. The obtained results indicate that the CCVT frequency response compensation is effective and suitable for traveling wave-based fault locators. |

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.
