Thunderstorm activity and lightning guard problem of the overhead transmission lines



Only in Russia because of dangerous weather environment economic waste figures up annually around 60 billions of rubles, as well as electricity supply network complex damage – nearly 5 billions of rubles.

William M. Daley, US Secretary of Commerce:«Weather is a big business. It’s not only the environment – it’s an integer economical indicator. Weather influences upon a seventh part of the economy, $ 1 trillion per year.»

Lightning guard problem of the overhead transmission lines



Lightning overvoltage

Safe lightning protection

Smoothly

Bad lightning protection or its deficiency

Power setback

Electricity supply system breakdown

Necessity of the remedial work

Production downtime or

customer curtailment

International fame and patents



Research advisor of the company – Georgy V. Podporkin, D.Sc. in engineering, professor of St. Petersburg Polytechnic University, Senior Member IEEEThe company has 16 patents. First generation technology (Long-Flashover Arresters LFA) was patented in Russia and abroad: Germany, Finland, France, Great Britain, Italy, USA.Moreover, at present moment are lodged application for patenting Second generation technology (Multi-Chamber System) in the following countries: USA, Mexico, India, China, Indonesia, Japan, Vietnam, Thailand, Korea, France, Italy, Germany, Spain, Finland, Sweden, Norway, Estonia, Latvia, Lithuania, Poland, Czech Republic, Hungary, Rumania, Bulgaria, Great Britain, Turkey, Brazil, Argentina, Australia, Republic of South Africa, Azerbaijan, Kazakhstan, Ukraine, Belorussia.Informative articles about company are publishing in the leading technical mass media both in Russia and overseas: (Energetik, Energetika, Etektrichestvo, Elektrotehnika, IEEE Transactions on Power Delivery, Proceedings International Conference on Lightning Protection (ICLP), Proceedings of Electricity Distribution International Conference (CIRED), International Symposium on Lightning Protection (SIPDA))

First generation solution: Long-Flashover Arresters



According to the Statute Concerning engineering policy in distributing electricity supply network complexIt 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 flashoversForming of the long discharge channelDischarge channel segmentationArcing fault prevention

Key qualities of LFA:Defense against lightning overvoltagesDefense the conductors from burnouts Prevention the lines from dumpingHigh reliability: current flows OFF the device Loop-Type Long-Flashover arrester for power lines 10kV,

the most popular in Russia



First generation solution: Long-Flashover Arresters

Comparison of different measures of reducing the quantity of insulated conductors damage

Second generation solution: Multi-chamber system (MCS)



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

Second generation solution: multi-chamber system
