This is two terms for the same device. Lightning appears as an electrical surge, just as switching surges do. Arresters are used to mitigate these surges, preventing excessive over voltages.
lightning arrestor prevents overvoltage from reaching the equipment it is protecting on its load side, by shorting to ground, a damping resistor is used to damp out the oscillation of the overvoltage...
surge arrestor is a device which is used to normalize the transient deveoped in the system due to faults occurring in the overhead lines,these faults maily occur due to thunder and flashing of light...
Their purpose is completely different. A wavetrap is placed in series with a line, and is meant to block specific high frequencies (usually used in power line carrier communication schemes - a high...
OK, basically there are two types of arrester , namely Direct arrester (Lightning arrester) & indirect lightning arrester (surge arrester).Direct arrester are copper rod of 5 to 6 feet long used...
Neon and other noble gases require a high voltage to conduct electricity, so that normally current will not flow across them. However, a direct lightning strike (such as on a radio tower antenna)...
