Surge protection system

Protection against lightning surges

Surge collision protection is essential for the Data Center. It is used to protect against overvoltage, overcurrent, or surge caused by a circuit break or by lightning. Surge arresters reduce or eliminate excess current or voltage.

The current electrical, electronic, and communication equipment have been developed. The device is smaller in size and higher in value. These devices are quite fragile when the circuit breaks and a lightning strike occurs. The damage value of data in the organization cannot be compared with the cost of installing a surge arrester. Therefore, protective devices have been developed to prevent possible damage.

Surge protection also includes types used for communication, such as surge protection for LAN systems, coaxial cables. It can be seen that today there are many types of surge protection devices. Before installation, it must be selected to suit the purpose.

The most widely used world standard for lightning protection in buildings is the IEC or IEEE standard

  • The relevant IEC standards are:
    – IEC 61024-1: 1990-03: Protection of structures against lightning, Part 1: General principles
    – IEC 61312-1: 1995-02: Protection against lightning surges Part 1: General principles
    – IEC 61000-4 -5: 1995-02: Electromagnetic compatibility (EMC) Part 4: Test and measurement techniques Part 5: Surge immunity tests
    – IEC 60664-1: 2000-04: Insulation coordination for equipment in low voltage systems Part: 1 Printing materials, Requirements and Tests
  • IEEE related standards are:
    – IEEE C62.41-1991 IEEE Recommended Practices Over voltage surges in low voltage AC power circuits
    – IEEE C62.45-1992 IEEE Guidelines for Surge Testing for Equipment Connected to Low Voltage AC Power Circuits

The relevant IEC standard is/The relevant IEEE standard is for Thailand, whose standard for overvoltage protection in buildings is the Lightning Standard electromagnetic protection of "Thailand Institute of Technology under the auspices of HM The King's"
