Lightning & Surge Protection:
Transient surge voltages arise as a result of lightning discharge, switching operations in electric systems and electrostatic discharge. These Surge voltages often destroy electronic equipment and systems to a large extent. Damage is not just restricted to industrial and commercial systems. Building automation and everyday household appliances are also affected.
In order to prevent surge voltages from destroying electrical systems, all the interfaces at risk, such as signal inputs and power supplies, must be connected to surge protection devices. Depending on the application, components such as spark gaps, gas-filled surge arresters, varistors and suppressor diodes are arranged individually or combined in protective circuits
1. Saint Elmo Lightning Conductor (For Building & Plant Protection)
2. Flashtrab Lightning Arresters ( Stage 1 Powerline Protection)

The first protection stage is FLASHTRAB, a lightning current arrester with arc chopping spark gap, that is installed in the central power supply of the building as the most powerful protective device. Surge voltages are limited to < 0.9 kV with these standard protective devices. From a technical point of view, the best position for installation is directly after the incoming main feeder box.
3. Valvetrab Surge Arresters ( Stage 2 Powerline Protection)

VALVETRAB, a surge arrester based on varistors, must be installed as second protection stage before the r.c.c.b.s in each subdistribution. This protection stage limits the remaining residual voltage over the lightning current arrester. In this way, switchgear, overcurrent triggers and r.c.c.b.s in the subdistribution and in circuit lines are sufficiently protected
4. Datatrab (Information Technology & Telecommunication Protection)

Information technology (IT) is another important application area for surge protection. Even when the power supplying the IT equipment is protected, you should be concerned about the data and telecommunication lines themselves. In the IT area, surge influences can come from internal influences such as motors, HVAC systems, drives, arc-welders, etc. Additionally, when the cabling of Information Technology system leaves the facility, lightning influences should also be considered.
Important application considerations for Information Technology solutions include:
5. Coaxtrab (Transceiver Protection)

Application:
Radio, video, and satellite systems are particularly susceptible to lightning influences. As with other signal applications, the influences can be due to direct or indirect lightning events. The antenna and/or connecting cables commonly used for such applications, despite their relatively good shielding properties, are extremely vulnerable to large electro-magnetic forces (such as lightning). Of volts, and can happen during monsoon season without any lightning strike.
Generally, transceiver protection refers to any system using coaxial cable for the data transmission medium. This includes video security, CCTV, CATC, GSM, FHSS, satellite, and other high frequency applications.
6. Termitrab (Measurement & Control Protection)

Application: Effective surge and lightning protection does not stop at protection of your power supply lines. Measurement and control signals also need to be considered as they are additional pathways for transient voltage and current to travel into sensitive electronics.
Measurement and control signals are used in many different commercial, Industrial and telecommunications applications. Those that tend to be most vulnerable to lightning and surge activity include those used for process control, manufacturing, instrumentation, HVAC systems, Security and alarm, and remote monitoring.
