Protection against lightning surges<\/span><\/h3>\n

\"\"<\/span><\/p>\n

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.<\/span><\/p>\n

\n

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.<\/span><\/p>\n

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.<\/span><\/p>\n

The most widely used world standard for lightning protection in buildings is the IEC or IEEE standard<\/span><\/p>\n
