Gas-insulated high-voltage switchgear (GIS) is a compact metal encapsulated switchgear consisting of high-voltage components such as circuit-breakers and disconnectors, which can be safely operated in confined spaces. GIS technology is excellent for applications where space is limited, reliability needs are high and maintenance needs are low. GIS technology is wide spread in the world however due to a variety of reasons, North American utilities have been a bit reluctant to fully adopt the technology. This reluctance is slowly diminishing, and GIS projects are on the rise. Given the relative novelty of the technology, an adjustment period involving exposure and training will be needed for the industry to fully embrace this technology. Hence by popular demand, this 4-hour workshop has been designed to provide in depth familiarity with High Voltage GIS technology for EPC contractors, commissioning professionals, user engineers and operators. Participants will leave with a fundamental understanding of:
- HV GIS basics
- GIS components
- Review of applicable guides and standards
- Field installation, case study and best practices
- Testing & Commissioning, best practices
- AC High Voltage Testing and Partial Discharge measurements
- Interface testing concerns (cables, transformer and metering devices)
- Operations and monitoring
- SF6 Safety and environmental considerations
This workshop contains 170 colorful and photo rich slides and is well-coordinated. The workshop has been specifically designed to be mid-level technical, to engage all audiences and be effective.
The workshop will be conducted by Sean Parsi P.E. Sean is the Managing Director of Dexotech Inc, a specialty testing and engineering company mainly concentrating on high voltage diagnostics, condition assessment and forensics with specialties in switchgear systems. Sean is a contributing member of Cigre D.166(Partial Discharge Monitoring of GIS), IEEE-Substations K0(GIS) , IEEE-Switchgear and Vice Chair of IEEE C37.301(standard for Partial Discharge testing and assessment of switchgear assemblies above 1kV). Sean has been directly involved with GIS technologies for over 15 years, with experience in construction and commissioning of over 50 substations across the globe as well as many more HV GIS commission and Partial Discharge assessment projects
