Product Uses
Pad-mounted transformers are ground-level, enclosed electrical transformers commonly used in urban and suburban power distribution systems. Their key applications include:
-
Underground Power Distribution Networks
Widely deployed in areas with underground cables (e.g., residential neighborhoods, commercial districts) to step down medium voltage (e.g., 15–35 kV) to low voltage (120/240V or 480V) for end users. -
Commercial & Industrial Facilities
Provide localized power transformation for shopping malls, office buildings, factories, and data centers where aesthetics, safety, and space efficiency are priorities. -
Residential Subdivisions
Serve as distribution nodes in housing developments, ensuring safe and reliable power delivery while minimizing visual and noise impact. -
Renewable Energy Integration
Used in solar/wind farms to step up or down voltage before feeding into the grid or supplying nearby communities. -
Public Infrastructure
Support hospitals, schools, airports, and street lighting systems by integrating seamlessly into urban landscapes. -
Temporary Power Supply
Deployed for construction sites or emergency power restoration due to their modularity and quick installation.
Product Operate Guide
1. Shipment, Handling, Rigging & Storage
- Inspect the transformer for shipping damage upon arrival. Report any issues to the carrier immediately.
- Use only designated lifting lugs and appropriate rigging equipment rated for the transformer’s weight. Never lift by bushings or radiators.
- Store the transformer upright on a level, dry surface. Protect from weather and flooding. For long-term storage, seal all openings and monitor silica gel breathers.
2. Transformer Installation
- Crane Lifting & Rigging: Attach slings to marked lifting points. Use spreader bars if needed to avoid tank deformation.
- Jack & Skid: For short moves, use jacks and skids under the base. Move slowly and avoid sudden movements.
- Foundation: Place transformer on a flat, solid, non-combustible pad with proper drainage. Anchor as required by local codes.
- Compartment: Ensure HV and LV compartments are accessible and free of debris. Check gasket seals for integrity.
- Grounding: Connect tank and neutral points to a reliable earth ground per IEEE/NEC standards.
- High Voltage & Low Voltage Connections: Clean and torque all cable terminations to manufacturer’s specifications. Use proper lugs and insulation.
- Dielectric Fluid: Check oil level and top up with approved fluid if necessary. Sample oil for moisture and dielectric strength if required.
- Transformer Pressure: Verify pressure relief device is operational. Check for correct internal pressure or vacuum as specified.
- Other Aspects: Install required signage and barriers. Confirm all accessories are installed and functional.
3. Pre-Energization
- Perform insulation resistance and turns ratio tests. Confirm all connections are tight and correct.
- Verify tap changer is set to the correct position.
- Check oil level, absence of leaks, and operation of gauges and alarms.
4. Post-Energization
- Monitor for abnormal noise, vibration, or temperature rise.
- Check for oil leaks and monitor gauges for pressure and temperature.
- Record initial load and voltage readings.
5. Switching Operation
- Operate switches only under no-load conditions unless rated for load-break.
- Follow lockout/tagout procedures before maintenance.
- Use insulated tools and wear appropriate PPE.
6. Protection
- Ensure fuses, surge arresters, and relays are installed and rated correctly.
- Test protection devices per manufacturer’s recommendations.
7. Accessories
- Check operation of temperature gauges, pressure relief devices, oil level indicators, and gas relays.
- Maintain and calibrate accessories as required.
8. Maintenance
- Perform periodic inspections for leaks, corrosion, and proper operation of all devices.
- Sample and test dielectric fluid annually or as recommended.
- Clean bushings and compartments regularly.
9. Field Acceptance Test Guidelines
- Conduct insulation resistance, turns ratio, and winding resistance tests before energization.
- Compare results with factory test reports and standards (e.g., IEEE C57.12).
- Document all test results for future reference.
10. Tables and Procedures
- Refer to the manufacturer’s manual for torque values, oil specifications, and test limits.
- Maintain a log of all inspections, tests, and maintenance activities.
- Follow standard operating procedures for all field operations.
