GIS / HGIS Systems
TSEA integrates GIS and HGIS solutions for medium- and high-voltage substations where space optimization and operational continuity are required.
Based on gas-insulated technology (SF₆), these systems reduce physical footprint and support installation in urban environments, industrial facilities, and space-constrained applications.
Modular architecture and engineered integration enable operation under defined voltage and short-circuit levels, in accordance with applicable international technical standards.
Gas-Insulated Technology in Substations
Gas-insulated switchgear (GIS) technology uses SF₆ gas as the insulating medium, enclosing primary substation components within sealed compartments.
This configuration reduces installation footprint and limits exposure to humidity, pollution, and severe environmental conditions.
GIS and HGIS systems are applied in transmission and distribution projects where compact design and controlled operating conditions are required.
Key Advantages of TSEA-Integrated GIS / HGIS Solutions
- Engineering expertise in GIS / HGIS system integration
- Installation executed by qualified local teams
- Local technical support in Portuguese
- Compact substation footprint
- Designed for operation in demanding environmental conditions
- Defined protection and enclosure architecture supporting controlled operation
Compact Design and Operational Safety
GIS and HGIS solutions are designed to reduce substation footprint, supporting installations in urban environments, industrial sites, and projects with space or civil constraints.
Sealed compartments limit exposure to external agents, while integration with monitoring and automation systems supports controlled operation.
This configuration reduces exposure to environmental conditions and supports structured maintenance throughout the asset lifecycle.
Applications in Critical Environments
GIS / HGIS systems are applied in projects requiring continuous operation and controlled installation footprint, including:
- Urban substations with limited space
- Industrial facilities with operational constraints
- Essential infrastructure and public services
- Transmission and distribution projects in demanding environmental conditions
Their compact architecture and integration with protection and automation systems support stable operation under defined technical parameters.
TSEA integrates GIS and HGIS systems with protection, control, and supervision solutions (SPCS), delivering coordinated substation projects.
This approach aligns primary equipment and automation architecture, supporting structured system integration across transmission and distribution applications.
