Is Your Transformer Due for
Oil Filtration?
Contaminated oil reduces insulation strength and accelerates equipment failure. Petrozone delivers certified on-site filtration, purification, and treatment across Saudi Arabia.

The Problem
Degraded Transformer Oil Is a Silent Risk Most Facilities Ignore
Oil doesn't fail overnight. It degrades slowly — and most facilities only discover the problem after a fault has already occurred.
🔴 Low Dielectric Strength
When BDV drops below 30 kV the oil can no longer insulate. One electrical stress event can cause flashover and total transformer failure.
🔴 Moisture Contamination
Water in transformer oil accelerates insulation paper aging. Every doubling of moisture content approximately halves the transformer's remaining life.
🔴 Oxidation and Acidity
Oxidised oil attacks insulation paper irreversibly. Once acidity rises above 0.1 mgKOH/g the damage cannot be undone.

Real Results
Real Results From Actual Filtration Jobs
Before and after numbers from jobs completed by our team. These results are typical when filtration is performed by certified engineers with the right equipment.
| Parameter | ❌ Before Filtration | ✅ After Filtration |
|---|---|---|
| BDV (Dielectric Breakdown Voltage) | 24 kV | 72 kV |
| Moisture Content | 42 ppm | 4 ppm |
| Acidity (Neutralisation Number) | 0.12 mgKOH/g | 0.02 mgKOH/g |
| Oil Colour (ASTM D1500) | Dark Brown | Light Yellow |
| Dissolved Gas (DGA) | Elevated H₂ | Within Limits |
Results from jobs carried out by Petrozone engineers. Individual results depend on transformer rating, oil volume, and degree of degradation.
Our Solution
On-Site Transformer Oil Filtration by Certified Specialists
Petrozone carries out complete filtration and purification at your facility. No transport, no extended downtime.

Recent Projects
Work We Have Completed On-Site
Real jobs. Real results. Client names are confidential — industry, location, and specs are shown.
120 MVA Power Transformer — Oil Filtration
High-voltage transformer serving a critical water injection facility. BDV had deteriorated to unsafe levels.
Filtration completed without taking the unit offline. Full test report issued, accepted by facility's maintenance team.
33 kV Transformer — Oil Leak Repair
Petrochemical plant transformer with a severe oil leak from the main tank gasket, creating a fire risk and oil contamination concern.
Emergency mobilisation completed within 24 hours of initial call. Gasket replaced, oil topped up, transformer returned to full service. Written report issued.
35 MVA Power Transformer — Full Electrical Testing
Annual compliance testing required by facility maintenance schedule. Full electrical diagnostic suite carried out on-site.
Full written test report issued covering BDV, DGA, insulation resistance, tan delta, and winding resistance. Accepted by facility maintenance team for audit records.
60 MVA Power Transformer — Radiator Replacement
Transformer radiator bank was damaged and corroded, causing inadequate cooling and elevated oil temperature under load.
Complete radiator bank replaced on-site. Transformer returned to full rated load operation. Oil temperature brought within IEC operating limits.

Financial Case
Why Filtration Makes Financial Sense
Maintenance managers know the technical case. Management thinks in money. Here is the financial argument.
Prevent Costly Downtime
Reduce the risk of transformer failures that can interrupt production and impact plant operations. A planned filtration program keeps your equipment running — on your schedule, not emergency call-outs.
Extend Asset Life
Remove moisture and contaminants that accelerate insulation aging and transformer deterioration. Well-maintained oil keeps your transformer healthy for significantly longer.
Lower Long-Term Costs
A planned filtration program costs significantly less than major repairs, rewinding, or transformer replacement. Prevention is always cheaper than failure.
