Potential Transformer (PT) & Surge Protection (SP) Cubicles / Lightening Arrestor Voltage Transformer Cubicles ( LAVT)
PT & SP Cubicles or LAVT cubicles are used for generator voltage measurement and generator protection from over voltages.
Neutral Grounding Cubicles
Generator Neutral Grounding Cubicles are designed to minimize fault damage incurred by generators, maintain sufficient fault detection and improve power system reliability.
Generator Terminal Enclosures (GTE) / Generator Auxiliary Compartment (GAC)
GTE or GAC is mounted on Generator top is used for monitoring & protection system components in a large housing. The enclosure includes both line-side and neutral-side bus systems.
Pressurization System
Pressurization System is used to maintain a positive pressure above atmospheric pressure by few millibars of dry and clean air inside the enclosures thus also eliminates any ingress of moisture and dust into the system.
Hot Air Blowing System
The hot air blowing system is open loop type used to blow hot air into the busduct to evacuate moisture inside the busduct during the startup and during shutdowns.
DC Busbar Systems
DC Busbar System are generally used for generator excitation system and in smelter plants for furnace connections.
