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.
The adventure has started with training the linemen who will be later mounting the LLPDs on the power line. In total, it was five teams with eight workers in each. We held a practical workshop at Pampanga Substation's warehouse. During the training, we presented the principle of LLPD – the EasyQuench system and focused on the features essential for the installation and maintenance crew.
In this chapter, you can find the Frequently Asked Questions on LLPD, inspired by our customers. We hope that the comprehensive answers will be useful for anyone interested in the lightning protection of overhead lines.
Prior to the large tender awarded by TNB to Streamer Electric AG, we conducted on-site trainings for the LLPD dM35z installation. The purpose of this activity was to educate the end-user personal for proper installation of LLPDs and selecting the most suitable accessories for each tower. The onsite training was conducted in four different cities: Selangor, Johor, Perak, and Kedah.
And here one more successful LLPD-project from China where Streamer has equipped 2 power lines with 150 pieces of Line Lightning Protection Devices 11kV for direct lightning protection, SAd10z and 100pcs for indirect lightning protection SAi10z inHuabei Oilfield Erlenhot Branch (Erenhot, Inner Mongolia).
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 key measures to prevent coronavirus are to avoid crowds, do not touch your face, and one of the most important is to minimize the interaction with surfaces of “popular objects” that are encountered by everyone.
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.
