Q: What is the meaning of 'eca3G'?

The initials of 'Energy Conversion Apparatus 3rd Generation.' Can be pronounced as 'εka three Gee!!'

Q: Is 'eca3G' a grounding device or a lightning protection device?

'eca3G' is both a grounding & lightning protection device, which enable creation of an optimistic grounding system (common grounding, equi-potential), and eliminate lightning surge currents at the same time. 'eca3G' is a lightning protection device to eliminate abnormal voltage & induced currents from lightning. 'eca3G' has a US patent (No. 7652865 B2) as "EARTHING DEVICE WHICH NEEDS NOT BE BURIED UNDER GROUND”

Q: How does 'eca3G' work?

By converting electrical characteristics of lightning surges to other energy forms such as heat & arc energy, neutralizes electrical characteristics, and forms an equi-potential environment to protect all the systems in the same space. This is the technology of the world’s first third generation digital grounding device securing a US patent and international patent.

Q: Who are the major clients of 'eca3G'?

eca3G has been installed for the Navy, Army, Air Force, National Institutions, Water Service Management Agency, Hydro-Nuclear Power Corporation, Gas Corporation, as well as at Railways, Subways, Road Construction Sites, Broadcasting Stations, Mobile Communication Service Providers, Mobile Shelters, etc. Protecting electronic communication facilities from lightning.

Q: What type of equipment does 'eca3G' protect?

eca3G protects Wire/Wireless Communication Equipment, Radars, Communication Vehicles, Measuring Control Equipment, Broadcast Facilities, CCTV Camera and Security Systems, Electronic Perimeter Systems, Anti-aircraft guns, Missiles, etc. with devices for protecting all electronic communication facilities from lightning and surges.

Q: What is the maximum surge current discharge capacity ‘eca3G’ can withstand?

For Power Supply: 100kA~420kA / For Communications: 50kA~200kASPD Model: 10kA~240kA

Q: How long is the warranty period of 'eca3G'?

Lightning Protection Model (LM, SM, TM, TNC): 5 years, Surge Protection Model: 3 years

Q: Can 'eca3G' be used where there is no grounding?

Yes. 'eca3G' can protect electronic/communication systems from lightning without a grounding system. We have plenty of proven experience for unmanned TV relay stations, unmanned forest fire monitoring systems, hydro-power dam surveillance system, fire-fighting agency wireless communication systems in deep mountainous areas, and plenty of others. This is one of the strengths of 'eca3G' and a key of the US patent.

Q: How to check if 'eca3G' is running under normal operational status?

There are indication lamps on the front panel.

Q: What is the electricity consumption of 'eca3G'?

Around 100 kWh per year. At normal status, diagnosis system requires small consumption to be ready for response of surge detection, and 'eca3G' will use surge electricity to protect system for 0.3 second when the surge invades. 'eca3G' electric consumption is very minimal.

Q: If there are several pieces of equipment (such as a communication unit, monitoring unit, computer, etc.) in the base station, how many power distribution panels be installed?

Typically, there is one power distribution panel in the base station to supply power to all the pieces of equipment. One 'eca3G-LM' will be installed to connect to the DB and each piece of equipment. If there is a UPS, AVR or small transformer, 'eca3G-SM' will be installed for each. If some of the equipment use a different power source, 'eca3G-LP / LS' will be installed.

Q: What is the meaning of 'eca3G' model names?

WW-XX-YY-ZZM
WW=> LM (for Main DB), SM (for sub DB), TM (for Rack )
XX=> 12 (Single phase, 2 wire), 33 (3 phase, 3 wire), 34 (3 phase, 4 wire)
YY=> 10: 100V~130V, 20: 200V~240V, 38: 360V~440V.

How many pieces of equipment is used with 'eca3G'?

① One for each DB
② One 'eca3G' can be connected with 10 pieces of equipment
③ One 'eca3G' for each generator
④ One 'eca3G' for each UPS (AVR)
⑤ One 'eca3G' for low voltage DB at main power supply station
⑥ If distance from DB is over 30M, install additional LS / LP
⑦ If there is an insulation transformer, an additional 'eca3G' will be installed
