Leaking transformers can be a costly problem:
- Moisture and oxygen can enter a transformer through leaking gaskets causing accelerated aging of insulation and insulation failure.
- Leaking oil can get onto the ground and possibly into groundwater, which can be expensive to remedy; leaking oil can carry lead from transformer paint (if paint is lead-based) into the ground causing further contamination.
- Leaks above the transformer oil can allow the nitrogen blanket to escape, causing more frequent nitrogen bottle replacement if provided with a positive pressure system.
Industrial Tests can help solve your leak problems!
We can either fix just the leaking location(s) or completely regasket all transformer openings and reprocess the oil to put equipment back in good condition; the scope of the job is up to the customer.Steps Involved In Regasketing a Transformer:
- Acceptance of Clearance
- Ground Transformer
- Establish Baselines
- Analyze Baseline Data for Problems
- Drain Oil
- Re gasket All Openings on Outside of Tank
- Visually Inspect LTC for Problems and Advise
- Pressure Test with Dry Air
- Perform Vacuum Drop Test
- Pull Vacuum/Process Transformer per Customer Specifications
- Refill Transformer with Vacuum Degasified Oil
- Implement System Checks
- Compare System Checks to Baselines
- Walk-Through with Customer
- Unground Transformer
- Issue Final Project Report
