Lightning rod pulls lightning, and grounding provides the entry for electricity. KSC-IEC was amended from independent ground to common ground in 2005, but it is still independent ground. Lightning reacts electrically at 300,000km/sec, and does a very wide damage. Lightning electricity breaks electronic equipment down through the land, water pipes, gas pipes, electric wire, or grounding cable. TN ground should be adopted in Korea, but can’t be adopted due to earth leakage breaker. standard common ground based on equipotential theory can’t be configured where there is ELB. It is because it’s difficult to determine or notify what the invisible lightning electricity did. The sites are not well aware because the amended KSC-IEC standard is promoted or trained.

It protects against damage, breakdown, or malfunction of electronic equipment despite lightning. Electronic equipment operates normally despite lightning around, and never breaks down. ELB never trips despite any lightning. CCTV, fire alarm controller, communication facility, and security system operate normally despite any lightning. There is absolutely no breakdown of electronic equipment caused by unknown reason. Electronic equipment can be operated stably without lightning rod and grounding. Lightning damages are completely prevented to protect against recovery cost, manpower, financial and business loss.

Solve the crashing issues between KS C-IEC’s TN method and extension regulations (ELB installation). Form common grounding based on equipotential theory and maintain the potential difference within 0.2V. In places with ELB, form TN method from the output through electromagnetic circuit separation. Improve the independent grounding of KS C-9609 in the past to the amended KS C-IEC standard in 2005. “Install lightning protection system (excluding lightning rod) and grounding facility” in Article 18 of the Radio Equipment Regulation. Review the error/problem thoroughly, and determine KS C-IEC standard correctly through perception change.

Maintain the TN method and equipotentiality below 0.1V through TNC model (performance-guaranteed product). In places with ELB, form TN method electromagnetic circuit separation of TNC model. Improve the independent grounding of KS C-9609 in the past to the amended KS C-IEC standard by installing eca3G. “Install lightning protection system (excluding lightning rod) and grounding facility” in Article 18 of the Radio Equipment Regulation by installing eca3G. In case of damage, offer 100% compensation through PL insurance.
