The influence of lightning induced voltage on the distribution power line polymer insulators
Protection of medium voltage (MV) overhead lines against the indirect effects of lightning is an important issue in Malaysia and other tropical countries. Protection of these lines against the indirect effects of lightning is a major concern and can be improved by several ways. The choice of insulator to be used for instance, between the glass, ceramic or polymer, can help to improve the line p...
متن کاملTall-Structure Lightning Return-Stroke Modelling
A lightning return-stroke model, based on the lightning return-stroke current derivative measured at the Toronto CN Tower is presented in this paper. A 3-section transmission line representation of the CN Tower along with the derivative of the modified Heidler function is used to simulate the measured current derivative signal. Reflections from major structural discontinuities of the CN Tower a...
متن کاملNoninvasive Voltage Measurement Through an On-chip Test Structure
A method to evaluate internal voltages through a builtin test structure is presented. Multiplexers are used to increase accessibility. The test structure does not affect normal operation of the circuit. Individual subcircuits can be tested selectivel,v based on evaiuated internal voltages.
متن کاملDesigning Concept on Lightning Protection of Overhead Power Distribution Line
The principle is shown for lightning protection of power distribution lines taking the effects of surge arresters, overhead ground wires and their combined use into consideration. Moreover an outline of a rational design method targeting direct lightning hits, induced overvoltages and backflow currents from high structures.
متن کاملPerformance of Medium Voltage Overhead Distribution Lines Against Lightning Discharges
The lightning discharges are one of the main causes of interruptions of medium voltage overhead distribution lines, being the reason of great concern for the utility companies. Its destructive effects frequently extends to equipments and connected installations, with the possibility to cause personal injuries and material damages, beyond economic losses, due to out of income and the possibility...
