Efficient fault detection of distribution transformers has great worth when installation of distribution transformers in the field is taken into account. Computer software has been developed which makes it possible to detect the region of fault location and evaluate the strength of insulation puncturing. It is capable of locating the position of fault along with total percentage of insulation breakdown region. Different evaluation tests are performed which are capable to recognize not only visible faults but also those faults in the windings of distribution transformers which cannot be...

This book describes number of aphid species attacking wheat varieties, population dynamics of aphid's species by collecting them from the field by using different collection techniques, and examine them in the laboratory under the microscope for the sake of species identification. The effect of abiotic factors on aphid's population was also determined. Four species of wheat aphid viz., Schizaphis graminum, Sitobion avenae, Rhopalosiphum padi and Rhopalosiphum maidis were identified on the basis of their taxonomic characters out of which S. graminum was most destructive. SARC-2 and SARC-8 were...
