WHAT IS THE OVER VOLTAGE HOLDER - SURGE ARRESTER?
Communication systems and electrical transmission facilities are always open for lightning.Since the conductivity of these systems is high, it is a serious risk that they are affected by lightning.The protection of the systems is partly provided by the over voltage holder - surge arresters.Thanks to this equipment, the lightning current is grounded in a short time and the over-current is directed to the system and the cause of the fault is partially prevented.
Where the Over Holder Surger Arrester Is Used?
- In Television / Radio transmitters
- In communication systems
- In power plants and production lines
- In railway facilities
Along with these, it is necessary to use the over voltage holder surge arresters in all areas where direct lightning may be the target.
What Are the Characteristics of the Over Voltage Holder Surge Arrester?
Unlike standard surge arresters, the over voltage holders have their own lightning arresters.Because the hardware is connected to the external system, it has the ability to direct over-current directly to the ground in lightning strikes.All electrical poles have the over voltage holder surge arrester. Compared to low voltage surge arresters, the voltage upper limits are higher and can partially provide the operation of the system by directly grounding the lightning.
Are Over Voltage Holders Sufficient Alone?
Lightning-induced damage is often found in electrical transmission poles, television and radio transmitters.In fact, there are regional interruptions due to lightning striking the power poles and power plants at certain periods every year.This indicates that the over voltage surge arresters found in all electrical installations alone are not sufficient.Although the upper limit of the surge arresters is high, the surge arises in the surge with excessive current, and the lightning arresters and surge arresters do not have the ability to limit the excess voltage in the system even though they have the ability to conduct the over current to the earth.
What to Do?
The surge arresters must be supplemented with surge voltage suppressor elements to prevent over-currents from lightning. It can also prevent the breakdown of the surge arresters in the electrical and communication facilities by preventing the peaking of an equipment current that provides voltage regulation. All of this can only be provided with Trimbox.
Why should Trimbox be used in Electrical and Communication Facilities?
- As stated in the article, no matter how high the surge voltage upper limit is, it must be supported by a stabilizer.Trimbox protects systems by damping over-voltage.
- Trimbox also serves as a surge arrester. It prevents the overflow that occurs in the lightning process from entering the system. It also allows the system to continue to operate. Therefore, the systems are completely protected from lightning effects.
- Together with all this, exceeding the upper voltage level of Trimbox is an extraordinary situation. In this case, however, Trimbox disconnects the system by pulling the voltage within itself, preventing the system from being damaged from high currents.
