When nature dictates the terms
06.03.2018Experts of EPM Columbia, Streamer's customer, demonstrated the power line equipped with surge arresters (SA). This conventional lightning protection device is widely used to protect power lines from lightning discharge impacts. Yet, with Colombia lines, these devices were not so effective: SAs installed on poles of power line had signs of damage. Many of them were out of use after direct lightning strokes.
This part of Latin America is exposed to the high thunderstorms activity. Moreover, the power line runs close to the city of Medellin, at an altitude of over 1400m above sea level, in extremely hilly terrain with high soil resistivity. The line, therefore, is subject to a large number of atmospheric overvoltages, and requires robust surge protection.
Surge arresters installed on pole mounted transformers, cable inputs, switchgear and other costly equipment in Colombia have a custom design that ensure quick replacement of a damaged unit with a new one. This also confirms the assumption that local linemen face this kind of issue quite often. In order to facilitate operational conditions of SAs, that protect sensitive equipment, and the equipment itself, Streamer have designed special line lightning protection devices (LLPDs), that can both dissipate overvoltages to the ground and interrupt the fault current at the same time.
Streamer LLPDs that have proven themselves to be very effective in regions of high thunderstorms activity, become more and more usual in Latin America. In particular, a 13,2 kV line was equipped with Streamer LLPDs in Colombia in December 2017. Within two months of operation, several one-time indicators have been triggered, three of them indicated operations of all LLPDs installed on one pole, that tells about a direct lightning stroke hit at this pole. No equipment failure or switchgear trips were observed on protected line after implementation of Streamer LLPDs. Which means that Streamer LLPDs had fulfilled their function and prevented detrimental consequences of direct lightning strokes hitting the line.
CIGRE 2022 finished last week
Streamer met with its old friends over the world - it was a nice and warm event, the first big one after the Covid times. CIGRE was also very useful in setting up new cooperation opportunities, mostly in the European region.
First LLPD installation for E-Distribuzione near Oderzo, Veneto, Italy
In 2019, the University of Napoli contacted Streamer Electric AG in order the find a lightning protection solution for medium voltage lines. Prof. Amedeo Andreotti was looking for medium voltage line protection devices for E-Distribuzione, the Distribution utility of Italy, part of the ENEL group owner of the electrical network in Italy but also many other electrical networks around the world. E- Distribuzione is actively looking to improve the lightning outage rate on their overhead line network and particularly in the northern part of Italy.
FIREX International Exhibition 2022 finished
The new LLPD Catalog 2022 is available for downloads
Some significant improvements implemented inside the document will help the user to better understand Streamer product portfolio and especially topics related to EasyQuench system and Line Lightning Protection Device product range, its operation principles and added values.
The international exhibition Intersec Expo finished this week
At the end of September, Streamer's topics have been presented at ICLP-SIPDA
The ICLP-SIPDA 2021 is a conference organized by the scientific committees of the International Conference on Lightning Protection (ICLP) and the International Symposium on lightning Protection (SIPDA). Conference took place from 20th to 26th September 2021. One of the two representatives from Streamer, Alexander Chusov, shared information about this conference and his thoughts about it
Ivan Zhitenev took part in the 50th St. Gallen symposium
The St. Gallen Symposium is a student initiative aimed at fostering an intergenerational dialogue and bringing world leaders and experts together.

First installation of TRANSEC units in Ecuador
Vietnam Ha Giang Power Company will test Streamer innovative devices of lightning protection.
Ha Giang is a mountainous province with a complex topography and experiences extremely high lightning density during the thunderstorm season. 110 kV lines in the province mostly pass through mountainous terrain, many rivers, and streams, so breaks of the line wires due to lightning, are not uncommon. Most of the problem areas are concentrated in areas such as the Nam Ngan hydroelectric power plant and the city of Viet Kuang. Installation of innovative lightning protection devices to provide the region with uninterrupted power supply was necessary.
