Lightning Detection & Earthing

Overview

The Lightning Detection System Laboratory (LDS) is an extensive research laboratory that focuses on the real-time detection of lightning activities in the Peninsular Malaysia.

Our laboratory was established in November 1994 and it was initially responsible to operate and manage installed Lightning Detection System Network to reduce the impacts of lightning-caused disturbances on Tenaga Nasional Berhad Transmission Grid system.

Over the years, the LDS has found increasing applications internally in TNB and externally at large for various lightning studies, protection and problem mitigation purposes.
