What Equipment Supports Successful GIS Commissioning?
The successful energization of a 1000 kV UHV GIS substation requires strict control of gas quality, vacuum conditions, leak tightness, and equipment reliability throughout manufacturing, transportation, installation, and commissioning.
To support these critical processes, specialized gas handling and testing equipment are widely used during factory acceptance testing (FAT) and site acceptance testing (SAT), including:
SF₆ Gas Recovery and Filling Systems
Used for:
- Vacuum evacuation before gas filling
- SF₆ gas filling and topping-up
- Gas recovery during maintenance
- Gas purification and recycling
KSTONE provides fully automatic SF₆ gas recovery units designed for GIS, GIL, and circuit breaker applications.
SF₆ Gas Quality Analyzers
Before energization, utilities typically verify:
- SF₆ purity
- Moisture content
- Decomposition products
Accurate gas analysis helps ensure insulation performance and long-term operational reliability.
SF₆ Leak Detection Equipment
Leak testing is a critical part of both FAT and SAT procedures.
Portable and quantitative leak detectors are used to verify the integrity of:
- GIS compartments
- Flanges and seals
- Gas piping systems
High-Capacity Vacuum Pumping Systems
For UHV GIS projects, achieving the required vacuum level is essential before gas filling.
Vacuum systems help remove:
- Moisture
- Air
- Contaminants
thereby improving insulation performance and reducing long-term failure risks.
