The safety tips of Oil Immersed Transformer

Here are key safety tips for handling and maintaining an Oil-Immersed Transformer:

1. Proper Installation

Location: Install in a well-ventilated, dry area away from flammable materials.

Foundation: Place on a firm, vibration-free foundation to prevent movement or tilting.

Clearance: Maintain safe distances around the transformer for heat dissipation and maintenance access.

2. Regular Inspection & Maintenance

Oil Level Check: Ensure the insulating oil level is within the prescribed limits.

Oil Quality Testing: Periodically test for moisture, acidity, and dielectric strength.

Leak Inspection: Check for oil leaks and seal faults regularly.

Bushing Inspection: Inspect for cracks or contamination on insulators.

3. Electrical Safety

Earthing (Grounding): Ensure proper grounding to avoid electric shocks and protect from lightning.

Load Monitoring: Avoid overloading the transformer to prevent overheating and damage.

Protection Devices: Use fuses, circuit breakers, and relays to guard against short circuits and overcurrent.

4. Fire Safety

Fire Extinguishers: Keep CO₂ or dry chemical extinguishers nearby.

Flame-Proof Enclosures: For indoor installations, use fire-resistant barriers or enclosures.

Temperature Control: Use temperature sensors to monitor for abnormal rises.

5. During Operation

Noise & Vibration Monitoring: Unusual sounds may indicate internal faults.

Cooling System Check: Make sure radiator fans or oil pumps (if present) work properly.

Don't Open Energized Transformer: Never open the tank or bushings while in service.

6. Personnel Safety

Trained Staff Only: Only qualified technicians should operate or maintain the transformer.

PPE Required: Use gloves, safety glasses, insulating mats, and flame-retardant clothing during maintenance.

Lockout/Tagout: Always de-energize and tag the system before service.
