High voltage hybrid air/gas insulated switchgear

HV hybrid switchgear

Configurable switchgear solutions to meet HV substation needs

The TGOOD Hybrid Primary (THP) is a type of hybrid gas insulated switchgear (HGIS). ‘Hybrid’ means it integrates advantages of air insulated and gas insulated switchgear, using mature and reliable components of both AIS and GIS busbar modules.

TGOOD’s compact HGIS modules may be ground supported or assembled as part of a compact substation complete with a prefabricated ehouse or electrical kiosk.

Product Overview

For use in affordable air insulated substations, HGIS technology allows additional components to be incorporated into the SF6 gas insulated circuit breaker.
Optional components include current transformers, potential transformers, surge arrestors, isolation and grounding switches; in a wide variety of configurations.
Compact prefabricated modules are ideal for expansions and retrofits within existing substation footprint.
May be assembled as part of a compact substation complete with a prefabricated ehouse.

Flexible

TGOOD’s HGIS requires up to 70% less surface area than comparable air insulated components.
Easy to install, prefabricated modules allow for rapid expansion of substations.
Option to mount HGIS on ehouse roof conserves space and simplifies construction works.
Reliable
Installation of a single self-contained module eliminates much of the installation risks compared to multiple air insulated components.
Reduced number of exposed parts compared to air insulated systems, minimising the risk of failure due to environmental conditions.

Capable

Smart technology enables online monitoring, data analysis and automated diagnosis to keep operation safe and reliable at all times.
Modules can be energised within 24 hours of delivery.
