The Application and Selection of Lightning Arresters
When a wave E1 traveling on surge impedance Z1 encounters another surge impedance Z2, the voltage on the new wave Z2 becomes: E2 = E1( 2 * Z2 ) E1 + E2 . Note: as the new surge impedance Z2 approaches infinity, representative of an open line, E2 = 2E1. The reflected wave will actually double in magnitude in its return in the opposite direction.

Types of Lightning Arresters - Circuit Globe
Types of Lightning Arresters The lightning arrester protects the electrical equipment from lightning. It is placed very near to the equipment and when the lightning occurs the arrester diverts the high voltage wave of lightning to the ground.
What's the Difference Between Surge Arresters and TVSSs ...
New NEC requirements make it important to understand the difference between surge protectors, surge arresters, and transient voltage surge suppressors The term surge protector can describe any device that protects against surges, which are excess voltages either impulses or sustained AC overvoltages.
Separate the Arresters From the Suppressors Electrical ...
The NEC distinguishes between surge arresters and transient voltage surge suppressors (TVSSs), yet both provide surge protection. What's the difference between them? Surge arresters generally apply to only the supply side (line side) of the meter (280.22), whereas TVSS devices generally apply to only the load side (285.21).
MOV or SASD Which Surge Suppressor is Right for You?
When a lightning current hits a power line, it's conducted to ground through a surge arrester or a flashover on the power system. The current flowing through the system's line and ground impedance causes a high-voltage transient (rise time of a few microseconds and a tail of tens of microseconds).
What is the difference between Surge arrester and surge ...
The simple answer is that a surge arrester directs the above voltage surge to ground while a surge suppressor soaks the energy up and re-emits it as heat. The two terms are often misused and sometime a better quality will also have a very small arrester included as part of the package. The average ...
