BWatch monitors SF6, circuit breaker condition and internal arc localisation.
PDWatch monitors continuously the partial discharge level, using external or internal UHF captors.
Both electronic devices are equipped with advanced communication features; this enables remote access and analysis functions on substation or upper level.
GIS Modernisation for aging GIS Switchgears
Cost effective life extension solution by avoiding complete shutdown and major civil works, our GIS modernisation solution helps customers to determine the best solution according to your needs. This solution reduces downtime, increases reliability of the equipment while reducing SF6 volume and losses.
Based on age and condition of equipment, our engineers will design a retrofit solution that can extend equipment lifetime up.
This solution may adapt new design circuit-breakers, accessories as well advanced monitoring devices, control and protection systems, SF6 tightness renovation, earthing switch mechanisms and replacement of bursting discs, filling valves, moisture absorbers…
GIS extension and upgrades
Typical extensions are additional bays, while new requirements on short circuit, nominal current ratings, evolving EMC specifications, partial discharge sensors are examples of upgrades solutions as well new VT’s and CT’s to cover new network requirements
GIS spare parts
In order to minimise delays due to parts ordering and delivery process, Alstom Grid proposes strategic spare part inventory designed according to specific installed base by leveraging global service experience and statistics.
Maintenance kits are designed based on aggregated service experience in order to offer comprehensive components and instructions for replacement during preventive maintenances.
Several training courses are available in our training centers for operations and maintenance per GIS product range, covering as well monitoring devices and SF6 management.
