Site Preparation and Survey:
- Conduct a site survey to assess the installation location for the transformer and circuit breakers.
- Ensure that the site meets safety, accessibility, and environmental requirements.
- Prepare the site by clearing obstacles, leveling the ground, and providing adequate space for installation.
Foundation Construction:
- Design and construct a suitable foundation for the transformer and circuit breakers, considering factors such as soil conditions, load-bearing capacity, and seismic requirements.
- Excavate the foundation pit, install reinforcement, and pour concrete to create a stable and level base.
Transportation and Handling:
- Arrange for the transportation of the transformer and circuit breakers to the installation site using appropriate vehicles and handling equipment.
- Ensure safe handling and transportation practices to prevent damage during transit.
Transformer Installation:
- Position the transformer on the foundation using lifting equipment such as cranes or forklifts.
- Securely anchor the transformer to the foundation to withstand environmental conditions and operational loads.
- Connect the transformer to incoming and outgoing cables, busbars, and grounding systems according to manufacturer specifications and electrical drawings.
Circuit Breaker Installation:
- Mount the circuit breakers (VCB, SF6, or OCB) on their respective foundations or support structures.
- Install auxiliary equipment such as control panels, relay panels, and interlocking systems as per design requirements.
- Connect the circuit breakers to the electrical network, including incoming and outgoing cables, control wiring, and communication interfaces.
Interconnection and Testing:
- Establish interconnections between the transformer, circuit breakers, and associated equipment to form a complete electrical system.
- Conduct pre-commissioning tests and checks to verify the integrity of electrical connections, insulation, and mechanical stability.
Commissioning and Energization:
- Commission the transformer and circuit breakers by gradually energizing the system and testing its performance under various operating conditions.
- Verify the functionality of protective relays, monitoring devices, and control systems.
- Adjust settings and parameters as necessary to optimize the operation of the equipment and ensure compliance with operational requirements and safety standards.
Documentation and Handover:
- Prepare comprehensive documentation including installation records, test reports, as-built drawings, and operation manuals.
- Conduct a final inspection and acceptance procedure to confirm that the installation meets the client’s specifications and regulatory requirements.
- Provide training to operators and maintenance personnel on the operation, maintenance, and troubleshooting of the installed equipment.
