Modern power systems involve large amount of investment. An electric power system comprises of generation, transmission and distribution of electric energy. Growth of power systems has lead to very complex networks extended across large areas. In such situations, the proper functioning of a modern power system is heavily dependent upon the healthy operation of the transmission lines within it. ...

The series capacitor compensation is one of the key technologies in the EHV and UHV long distance power transmission lines. This paper analyzes the operation characteristics of the main protection combined with the engineering practice when the transmission line overcompensation due to the series compensation system is modified and analyzes the influence of the transition resistance and the sys...

Power cable is widely used in Extra High Voltage (EHV), High Voltage (HV) transmission, Medium Voltage (MV) sub-transmission, and MV / Low Voltage (LV) distribution applications. Basically, the protection principles used for cable are similar with the ones for overhead transmission line. However, the inherent characteristics of cables make its fault behavior more complicate than that of transmi...

This study aimed to investigate the neuropathogenesis of equine herpes virus 9 (EHV-9) by studying the effects of a single point mutation introduced in two different EHV-9 genes. The two EHV-9 mutants, 14R and 19R, were generated carrying a point mutation in two separate EHV-9 genes. These mutants, along with the wild-type EHV-9, were used to infect a hamster model. The EHV-9- and 19R-infected ...

A total of 51 sera from a migratory population of Burchell's zebras (Equus burchelli) were collected in the Serengeti National Park (Tanzania) between 1999 and 2001 to assess levels of exposure to equine herpesvirus types 1, 2, 4, 9 (EHV-1, -2, -4, -9), EHV-1 zebra isolate T965, and equine arteritis virus (EAV). Using virus-specific neutralizing antibody tests, seroprevalence was high for EHV-9...

Recently new threats to humans are observed from electromagnetic radiation from various sources like mobile phones, transmission lines and many more. For providing continuous and uninterrupted supply of electric power to consumer’s maintenance operation of high voltage power lines are often performed with systems energized or live. This is referred as Hot Line maintenance or live line maintenan...
