Installation upgrades Limpopo substation

Schneider Electric has installed the company’s first new-generation Premset SSIS (shielded, solid insulation system) modular switchgear at the Stubb Street Substation in Makhado (Louis Trichardt), Limpopo. It is the first of five substations to be renovated to maintain a stable electricity supply, as the town continues to develop. The installation resulted in the substation going from being a rather noisy, often failing and difficult-to-maintain system, to a quiet, reliable substation with fewer trips. The sound of partial discharge from the substation has disappeared. The smart grid features that come with the switchgear make diagnosis easier. Premset uses solid and shielded insulation, which offers unprecedented safety, efficiency and ease of use. The main circuit components are insulated by a layer of solid material, covered by an external conductive coating with ground potential. There is no electric field in the ambient air, because live conductors and the ground are confined within the switchgear enclosure.
