What are transient overvoltages?
Transient overvoltages are brief increases in voltage, measured between two conductors or between a conductor and ground. These increases can be caused by atmospheric electrical discharges (lightning) or by switching processes or breakdowns, such as ground contact or short circuits.
These surges can cause premature aging of components and damage equipment connected to the electrical network.
How can we protect ourselves?
To protect the installations against these transient overvoltages, there are protection devices such as gas discharge tubes, zinc oxide varistors, suppressor diodes, spark gaps, among others.
These devices are divided into three types according to the level of protection they offer:
- TYPE 1 Protector: Protects against direct lightning strikes and is installed in places where the currents and electromagnetic effects of lightning are not attenuated.
- TYPE 2 Protector: Limits transient overvoltages and diverts currents to earth to protect installation and electrical equipment. It is installed in places where the currents and electromagnetic effects of lightning are attenuated.
- TYPE 3 Protector: Protects against more attenuated industrial surges and is installed near sensitive equipment or more than 30 meters from the previous protector.
Do you need any of these devices?
At Aiditec Systems, we offer a wide range of surge protectors, including the types mentioned above, tested and certified to the relevant standards.
To find out if you need to install a protector, you can access our PROTECTOR SELECTION ASSISTANT and we will propose the most suitable model according to your indications.
