The surge arrester is a protection element that discharges very high pulses, such as lightning, by short-circuiting the excessively high changes brought on the flow diagram. High voltage, medium voltage and low voltage types are available.We will examine the low voltage range. Low voltage surge arrester is used as class B, C and D according to its functions.
Since this device has just begun to be known, it is also known to protect against over-voltages.
However, it does not attract any excessive stress on the system to the nominal level and even make no intervention. The function they do is to carry out the protection function, especially by transmitting over-currents to the soil.
Types;
B class surge arrester
By using before the counter of any structure, instantaneous currents up to 125kA are transmitted to the ground and prevent their entry into the system. Sensitivity is less than C and D class. Good grounding is needed.
C class surge arrester,
In the post-counter board of the building, it transmits current currents up to 20kA to the ground and prevent entry into the system.
Sensitivity is less than D class.
Good grounding is needed.
D class surge arrester,
In order to protect direct sensitive devices, applications are being made for systems that require more precision than class B and C sensitivity.It needs a very good grounding.Surge arresters, in summary, are the ones used by lightning rods in the electrical system to prevent the lightning strike directly into the structure.
That is, the lightning rod can transmit the lightning pulse outside the structure to the ground, cannot adjust the tension level, and the surge arrester can transmit the lightning pulse entering the electrical system inside the structure to the ground.
There are currents and voltages wherever there is electricity as in lightning.The surge arresters are used to prevent over-currents and Trimbox is used to prevent over-voltages.This is because the overvoltage between the two ends of the system cannot be prevented by the surge arrester and causes the devices in this system to burn.
In a system that uses Trimbox, damage to the over-voltage is prevented.In addition, there is no need for Low Voltage Surge Arrester.
