🔴 A SMALL OIL LEAK TODAY COULD BECOME A BIG PROBLEM TOMORROW!

Is your transformer showing signs of oil leakage?
Oil leaks are more than just a maintenance inconvenience. If left unattended, they can compromise transformer reliability and lead to costly repairs or unexpected downtime.

⚠️ WHAT CAN HAPPEN WHEN OIL LEAKS ARE IGNORED?

💧 Reduced Oil Levels – Can affect insulation and cooling performance.
🔥 Overheating – Insufficient oil can compromise the transformer's ability to dissipate heat.
⚡ Insulation Problems – Leaks may allow moisture to enter, particularly when the transformer cools.
🔧 Equipment Damage – Continued deterioration can result in expensive repairs or transformer failure.

At PNC Oil – Transformer & Substation Solutions, we provide professional transformer maintenance and repair services, including:
✅ Oil leak detection and rectification
✅ Gasket and seal replacement
✅ Transformer oil purification
✅ Oil refilling and vacuum treatment
✅ General transformer maintenance and repairs

DON'T WAIT FOR A SMALL LEAK TO BECOME A MAJOR FAILURE.

🔥 A loose or deteriorating electrical connection may look normal—until its temperature is checked.
Infrared thermographic scanning allows electrical equipment to be inspected while operating, helping to identify abnormal heat patterns that may indicate:
🔴 Loose or high-resistance connections
⚫ Overloaded components
🔴 Uneven phase loading
⚫ Deteriorating contacts or terminations
🔴 Developing equipment faults

Early detection allows maintenance teams to investigate and plan corrective work before the problem leads to equipment damage, an unexpected trip or production downtime.
PNC Oil provides infrared scanning and condition-assessment services for transformers, switchgear, substations and other critical electrical equipment.

Find the heat before it becomes a failure.

A transformer breather may be a small component, but it plays an important role in protecting the transformer’s insulating oil.

As the oil expands and contracts, the transformer draws air through the breather. If the silica gel is saturated, the oil level is incorrect, or the breather is damaged, moisture and contamination may enter the conservator and contribute to:

💧 Increased moisture in the insulating oil
⚡ Reduced insulation strength
🔴 Accelerated deterioration of the paper insulation
⚫ Sludge formation and reduced cooling efficiency
🔧 Increased maintenance and repair costs

Regular inspection should include the condition of the silica gel, the oil cup, seals, pipework and airflow.

⚡ What’s happening inside your transformer?

Transformer windings are one of the most critical components of a transformer, but deterioration can develop over time without being visible from the outside.

Heat, moisture, electrical stress, ageing insulation and contamination can gradually weaken the winding insulation.

If deterioration continues, it may contribute to:
🔥 Localised overheating and hot spots
⚡ Reduced insulation strength
⚠️ Turn-to-turn or phase faults
🔧 Extensive repairs or rewinding
⏱️ Unexpected downtime and production losses

Routine transformer maintenance, oil analysis and electrical testing can provide valuable information about developing problems and help maintenance teams make informed decisions before a major failure occurs.

At PNC Oil – Transformer & Substation Solutions, we inspect, test, maintain and repair transformers for industrial, mining and commercial applications.
Protect the winding. Protect the transformer. Protect your production.

PNC Oil provides on-site and workshop support for industrial, mining and commercial installations, including switchgear maintenance, circuit-breaker servicing, protection testing, electrical testing and fault finding.

🔧 Inspect.
⚡ Test.
🛠️ Maintain.

Moisture in transformer oil can become a serious reliability concern.

At PNC Oil – Transformer & Substation Solutions, our transformer oil purification services are designed to reduce moisture and contaminants and improve the condition of insulating oil.

For transformers with elevated moisture levels, effective treatment may require more than simply circulating the oil. Depending on the condition of the unit, vacuum treatment can also assist in addressing moisture retained within the transformer’s insulation system.

🔴 Transformer oil purification
⚫ Vacuum treatment
🔴 Oil sampling & laboratory testing
⚫ Oil replacement and filtration
🔴 Transformer maintenance & repairs

Protect the transformer before moisture becomes a bigger problem.
