An ANN Based Fault Diagnosis System for Tapped HV/EHV Power Transmission Lines

This paper presents a design for a fault diagnosis system (FDS) for tapped high/extra-high voltage (HV/EHV) power transmission lines (TL's). These tapped lines have two different protection zones. The proposed approach reduces the cost and the complexity of the FDS for these types of lines. The FDS, basically, utilizes fifteen artificial neural networks (ANN's) to reach its output diagnosis. Th...

Optimal Design of Grounding System for HV/ EHV Substations in Two Layered Soil

Successful operation of entire power system depends to a considerable extent on efficient and satisfactory performance of substations. Hence substations in general can be considered as heart of overall power system. In any substation, a well designed grounding plays an important role. Since absence of safe and effective grounding system can result in mal-operation or non-operation of control an...

On-line Partial Discharge Assessment and Monitoring of MV to EHV Cables

To effectively manage their electricity networks, owners and operators around the world have a very real need to understand the condition of their often ageing Transmission and Distribution assets. Of all the major asset classes, underground cables often have the least available condition data but at the same time have a significant impact on network performance. One of the predominant causes o...
