The aim of this study is to propose simple and reliable techniques to assess the condition of metal oxide arrester based on the dielectric response techniques. A number of modern electrical diagnostics for Metal Oxide Surge Arrester (MOSA) are discussed in this paper. The techniques included return voltage, decay voltage and polarisation/depolarisation current measurement. The single and multipulse current (8/20micros) was used to artificially degrade the MOSA. The before and after diagnostic ....etc

MODERN ZINC OXIDE SURGE ARRESTER



Introduction
The most important matter in a
power system is how to handle a fault condition. In power
system networks we have to maintain the voltage, current
and other network parameters at a specified value .
If an abnormal condition is occurred we
must take precaution against the abnormality to protect
the succeeding elements connected to the network.There
are many modern technique to clear the over voltage
condit ....etc

Voltage surges are unpredictable, momentary increases in voltage. Typically, lightning, inductive switching, or power switching cause surges, which can damage the insulation in building wiring, electrical appliances, or electronic equipment.

Power surges, which can create havoc with today's highly sensitive electrical and electronic equipment, are an unavoidable fact of life. Power surges, both voltage and current, are occurring continually in today?s power systems.

Whether they occur naturally, such as from lightning and static electri ....etc

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
