Power Frequency Overvoltages in Power Systems: The Power Frequency Overvoltages occur in large power systems and they are of much concern in EHV systems, i.e. systems of 400 kV and…
Switching Surges in Transmission Line: Till the time when the transmission voltages were about 220 kV and below, over-voltages due to lightning were of very high order and overvoltages generated…
Rectangular Travelling Wave: Reflection and transmission of a Rectangular Travelling Wave at junction points of unequal impedances in a transmission line are of great importance in transmission systems. Depending on…
Transmission of Waves at Transition Points: Whenever there is an abrupt change in the parameters of a transmission line, such as an open circuit or a termination, the travelling wave…
Travelling Waves on Transmission Lines: Any disturbance on a Travelling Waves on Transmission Lines or system such as sudden opening or closing of line, a short circuit or a fault…
Mathematical Model of Lightning Stroke: During the charge formation process, the cloud may be considered to be a nonÂconductor. Hence, various potentials may be assumed at different parts of the…
Impulse Voltage Test System: It is extremely difficult to control and adjust the Impulse Voltage Test System wave shapes for different load conditions as in the case of large capacitive…
Impulse measurements using Multiple Shield Enclosures and Signal Cable: Multiple Shield Enclosures - It is essential that leads, layout, and connections from the signal sources to the CRO are to be…
