Arc Discharge Protection (Direct Lightning Protection / Surge Protection)
-
Patent registered
-
Design registered
-
New product and new technology registered
-
World’s first direct lightning and surge protection test completed (Korea Electrotechnology Research Institute)
-
Direct lightning current test: 200 kV (10/350 μsec), protection verified for 5 times or more
-
Durability: 8 MJ × 5 times = 40 MJ or higher
-
When the potential difference exceeds 500 V, lightning energy is reduced to 1/120,000 through arc discharge
-
Prevents surge damage, the leading cause of failures in communication equipment
-
Voltage reduced to 1/120
-
Duration time reduced to 1/1000
Main Functions
-
Compared to other voltage regulators, efficiency exceeds 95%
-
Can be used semi-permanently with a single installation
-
Reduces cost burden
-
Proven delivery record with a maximum capacity of 20 MVA, the largest in the world
Additional Functions
-
In addition to the basic performance, various optional functions are available to fully meet customer requirements.

Control via 4 mA to 20 mA source, wired and wireless remote control, etc.
Applications
-
Equipment affected by power induction disturbances near KEPCO grounding systems
-
Equipment subject to ground-fault accidents such as lightning strikes and special high-voltage events
-
Equipment damaged by induced noise from grounding systems
-
High-end equipment requiring stable communication signals
-
Applicable to all facilities including communications, power supply, and lightning protection systems
Impedance Coil
-
Suppresses surge current using high-frequency impedance characteristics
-
Induces arc voltage between ground electrodes and main conductors when lightning surges are introduced
-
A circuit that diverts commercial-frequency leakage current to ground
Ground Electrode
-
When the potential difference exceeds 500 V, an arc is generated to dissipate energy
-
Symmetrical arrangement prevents localized discharge caused by lightning surges
-
Made of stainless steel, providing high durability against arc discharge
Lightning Surge Application Test Results (Waveform)
When 2.16 MV is applied using a direct lightning test generator, it can be confirmed that the voltage is reduced to 18 kV

Characteristics of Parallel Installation (Direct Grounding Rod) Method
-
Enables burial to a depth of 3 m or more using a direct-driving rod, and allows parallel construction methods
-
Suitable for low-resistance grounding work in confined spaces and helps prevent civil complaints
-
Robust connector coupling structure prevents separation during installation (stainless steel)
-
Vertical driving connection method allows compatibility even if intermediate cutting occurs due to underground rock
-
Fire-resistant and corrosion-resistant characteristics make it suitable for vulnerable environments
-
Easy handling of materials and simple installation process
