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.
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
The interim results of the work of the new TRANSEC are ready
The equipment at the Pavlovskaya HPP and Zatonskaya Power House of the Bashkir power-producing company was installed in May 2021 and has been actively operating for 3 months
Installation of TRANSEC at Shaturskaya CTTPP in Russia
The power plant was built over a hundred years ago and is one of the oldest in Russia
The first of the lightning protection devices, developed to be supplied to SGCC sites, was sent to carry out operational testing in Guangxi province.
The lightning protection device has successfully passed certification tests at CEPRI (Wuhan) owned by SGCC.
During the development, new design and process solutions were found and applied, resulting in improvements of technical characteristics and reducing the cost of a multi-chamber system – the main functional element of a lightning protection device whose design is protected by patents of the Russian Federation and PRC.

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.
