On 16th April 2019, IEEE Dielectrics and Electrical Insulation Society (DEIS) Malaysia Chapter, in collaboration with Malaysian High Voltage Network (MyHVnet), had organized an industrial visit to Janamanjung Main Intake Substation, Perak. The main objective of this visit was to learn about the implementation of Malaysia’s first and only gas insulated line (GIL) system. The system, which operates at 50Hz 500kV/4000A, was commissioned in 2015 to enable the connection between the Janamanjung substation to the 500kV overhead lines.
There were 20 participants from various academic institutions in Malaysia including UNITEN, UNIMAP, UTEM, UTHM, UTM, USM and TARC, as well as industry representatives from Tenaga Nasional Berhad (TNB) LABS, who joined the visit. The half-day programme started off with a presentation by Ir. Dr. Iryani Mohamed Rawi, who was part of the team deploying the GIL system, sharing some background about the project and her valuable first-hand experience undertaking it. After the presentation, a site visit was conducted, giving the participants clearer insight and exposure on the system. Then, a visit to the control room that monitors the performance of the GIL system concluded the programme.
The committee members of the IEEE DEIS Malaysia Chapter would like to express their sincere thanks to Grid Maintenance Department, TNB for allowing and accommodating the visit to Janamanjung Main Intake Substation. The support from the members of MyHVnet were also acknowledged for making the industrial visit a successful event.
