Power generation facilities require coordinated switching, protection and isolation between generators, transformers, busbars and outgoing transmission lines.
Fenarro provides circuit breakers, disconnectors and related high voltage equipment for thermal, hydroelectric and wind power applications. Equipment selection should be based on the system voltage, rated current, short-circuit level, switching duty, substation layout and site environmental conditions.
Outdoor substations require high voltage equipment for current interruption, equipment protection and clearly identifiable circuit isolation.
Circuit breakers interrupt operating and fault currents, while disconnectors establish the visible isolation gaps required for inspection and maintenance. Fenarro can review equipment configurations according to the single-line diagram, voltage level, rated current, bay layout, phase spacing, earthing requirements and environmental conditions.
Industrial facilities depend on reliable indoor high voltage equipment to protect transformers, motors, incoming feeders and production equipment.
Indoor vacuum circuit breakers interrupt normal and fault currents, while disconnect switches establish isolation points for maintenance. Equipment configuration should be confirmed according to the switchgear type, cabinet dimensions, rated voltage, rated current, short-circuit level, phase spacing, operating mechanism and interlocking requirements.
Transformer neutral-point complete equipment integrates the components required for neutral-point isolation, grounding coordination and overvoltage protection into one assembly.
The system may include a neutral-point disconnector, surge arrester, rod gap, current transformer, terminal box and supporting structure. The final configuration should be reviewed according to the transformer voltage, neutral-grounding method, protection requirements and installation layout.
