Lightning and Surge Protection Of Modern Electronic Systems

Introduction
In virtually all aspects of our modern lives, microprocessors and integrated circuits (ICs) are hard
at work processing digital data, controlling critical systems and communicating information
through ever-expanding global networks. These now common components have dramatically
lowered system costs while increasing the power and flexibility of modern electronic systems in a
manner unimaginable just a few years ago. Yet, few developers se ....etc

The development of the equipment and systems sensitive to lightning electromagnetic impulse (LEMP) requires more efficient protection measures within a new lightning protection zones (LPZ) concept. effective selection and application of these measures should be based on a probabilistic approach which may contain procedures like:
-recognition of all kinds of lightning influence on the structure and its sensitive equipment;
-selection of protection measures in respect of highest value of risk component and LPZ concept
-assessment of lightning ....etc

ABSTRACT
A long flashover arrester (LFA), which comprises of three flashover modules using the creeping discharge effect, is described in this paper. In this design, the total arrester stressing voltage is applied simultaneously to all of the three modules so that the voltage-time characteristics of the arresters are improved. It assured reliable protection of medium voltage (e.g., 10kv) over head power line against both ....etc

Lightning and Surge Protection in
Photovoltaic Installations
This article discusses about the scientific background and essential assumptions to be taken into account in case of the lightning and surge protection in photovoltaic installations. The aspects of standardization are also considered. conventional low-voltage power distribution systems
(CLVPDSs) standards are used as a guide and changed also as some characteristics of PVIs are different from that of CLVPDS. This system is applied to a applied to an actual grid-connected P ....etc
