10. First generation solution: Long-Flashover Arresters 10 Copyright © 2010 Streamer Inc. All rights reserved. LIGHTNING GUARD OF POWER GRIDS According to the Statute Concerning engineering policy in distributing electricity supply network complex It is necessary to install LFA on the transmission lines: - for overvoltage protection and against the cable burning on the lines with insulated conductors; - on the approach to electricity distribution plant of the substations; - for weak parts of the transmission line defending ; - in the regions with extremely high percentage of lightning outages. Operational principle of LFA: Protection of insulators against the lightning flashovers Forming of the long discharge channel Discharge channel segmentation Arcing fault prevention Key qualities of LFA: Defense against lightning overvoltages Defense the conductors from burnouts Prevention the lines from dumping High reliability: current flows OFF the device Loop-Type Long-Flashover arrester for power lines 10kV, the most popular in Russia

13. Second generation solution: Multi-chamber system (MCS) 13 Copyright © 2010 Streamer Inc. All rights reserved. LIGHTNING GUARD OF POWER GRIDS Structurally common and effective Multi-chamber arresters (MCA) Multi-chamber Insulators-arresters (MCIA) for 10-35 kV and higher. Advantages of usage MCS instead of suspension strand: - no lightning outages; - unbending of power line exploitation; - refusal of using towers ground wire; - reducing of weight and price of towers or reducing its quantity Advantages of Multi-chamber system have already been accepted by distribution companies, oil and gas complex companies, our foreign partners and by Russian Railway. Now these devices are installed in pilot production on the problem transmission lines: Volgogradenergo, Lukoil, TNK-BP
