New lightning protection technologies in Tenaga Nasional Berhad (Malaysia) 33 kV transmission line
03.06.2018The line is located in the open, without natural protection, exposed to frequent lightning impacts, and is characterized by high frequency of non-steady lightning outages.The line was built in an area characterized by high lightning density, absence of natural shielding and high soil resistivity. Not surprising, that it was exposed to outages resulted by lightning impacts. The lightning protection means previously deployed in power lines were II class metal oxide arresters (MOA). MOAs are effective with low earthing resistance.Their application with high earthing resistance (>15Ω) entails premature aging, high maintenance costs and reduced reliability of all power grid.
Poles are located in high soil resistivity area (top/middle layer > 200 Ωm) with earthing resistance > 15 Ω.
In June 2016, 33 kV distribution line was equipped with SAdM35z LLPDs and fault indicators under Lodestar brand (designed by A-TREE Research & Development Company Ltd.). For 10 months of line performance monitoring, from June 2016 to March 2017, the faults number was compared with the data on storm activity in the vicinity of the considered distribution line.
According to the line lightning performance analysis, prior to SAd35z installation, from January 2015 to May 2016 the line have been tripped 22 times. After SAd35z installation, from June 2016 to March 2017, there were only 3 outages. Therefore, SAd35z installation resulted in 86% reduction of lightning outages.
Cost of replacing prematurely-aged components of MOV arresters installed in areas with high soil resistivity decreased more than 10 times after SAdM35z application.
TNB recognized the results of the pilot project as positive and is planning large-scale SAd35z installation in distribution grids located in open areas and territories with high soil resistivity.

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.

The first Transec unit has been installed in Kazakhstan and Central Asia by Streamer
In mid-March 2020, the first installation of the Transec unit has been completed in Kazakhstan.
New LLPDs d69z have been installed in Indonesia.
Installation of a new type of LLPDs on the line in Indonesia has been completed in February 2020. Streamer and representatives of the Indonesian PLN power system will be testing the equipment for two years with the assistance of the friendly Bandung Institute in the name of professor Reynaldo Zoro and his team. This will result in open reports and presentations with the recommendations for use.
Favorable results of operation of the Transec unit at JSC Petrostal Metallurgical Plant
In August 2019, the Transec unit was in service in the subsidiary company of JSC Kirovsky Zavod. A short time ago, we have received an official letter with a recommendation to use our equipment.
