DB Board Maintenance

1. Full Visual Inspection
Check for overheating, discoloration, loose terminations, moisture ingress, rodent damage, and ageing components.

2. Cleaning & Decontamination
Remove dust, carbon tracking, rust, and oil residue. Clean busbars, breaker surfaces, and insulation barriers.

3. Torque & Tightening
Re‑tighten all lugs, terminals, neutral bars, earth bars, and breaker connections to eliminate hot spots.

4. Protection Device Testing
Test MCCBs, MCBs, earth leakage units, surge arresters, and metering modules for correct operation.

5. Busbar Condition Assessment
Inspect for heat marks, insulation damage, corrosion, and mechanical wear. Re‑insulate or replace if required.

6. Cable & Wiring Integrity
Check for brittle insulation, burnt conductors, incorrect sizing, poor terminations, and replace where necessary.

7. Functional Testing
Perform insulation resistance tests, continuity tests, trip tests, and earth loop impedance verification.

8. Load & Balancing Review
Assess load distribution across phases to prevent overloading and improve system stability.

9. Safety & Compliance Check
Verify compliance with SANS 10142, OHSA requirements, correct labeling, danger signage, and panel sealing.

10. Maintenance Report Issued
Provide a full photographic report, findings, risks, and corrective actions.

Why This Matters
A well‑maintained DB board prevents:
Nuisance tripping
Overheating and fire risk
Costly downtime
Equipment failure
Safety hazards for tenants and staff

Higher upfront
Lower upfront
Best For | Old, degraded, high‑risk transformers Routine maintenance

Filtration is excellent for maintenance, but virgin oil is the only way to fully reset transformer health when oil is severely aged or contaminated.

When a Virgin Oil Change Is Recommended

Oil test results show low kV, high acidity, or high moisture DGA indicates thermal faults, arcing, or excessive gas levels. Visible sludge or darkened oil. Transformer running hot or showing reduced performance
After major repairs or refurbishment
Before returning long‑idle transformers to service

Top Benefits of a Virgin Oil Change
Full Dielectric Strength Restoration
Fresh oil has high breakdown voltage, improving insulation between windings and reducing risk of flashover. Contaminated oil loses dielectric strength due to moisture, oxidation, and particles.

Improved Cooling Efficiency
New oil circulates heat more effectively, lowering operating temperature and slowing insulation ageing. Overheated transformers fail faster.

Reset of Acidity & Oxidation Levels
Old oil becomes acidic over time, forming sludge that blocks cooling channels. Virgin oil resets acidity to near‑zero, preventing sludge formation.

Extended Transformer Lifespan
Clean oil slows the ageing of cellulose insulation the component that ultimately determines transformer end‑of‑life

Compliance With Standards
Virgin oil meets IEC 60296 requirements for new mineral insulating oil, ensuring safe commissioning and long‑term reliability.

Immediate Performance Improvement
Transformers run cooler, quieter, and more stable after a virgin oil change, especially units that have been in service for 10–20+ years.
