The Need for Transformer Maintenance
Transformers, like all equipment, age over time. The pivotal factor influencing a transformer’s lifespan is the quality of the insulating paper used within its windings. Without proper maintenance, this paper quality can deteriorate, eventually leading to transformer failure.
The consequences of a transformer failure can be catastrophic and result in power outages that can last for months, impacting the operations dependent on it. To prevent such situations, we strongly recommend Annual Transformer Preventive Maintenance.
What a Transformer Failure Actually Costs
Average unplanned outage after a transformer failure — halting production and triggering penalty clauses.
Emergency repairs, lost production, and expedited parts — costs that dwarf any maintenance program.
A new power transformer can take 3–6 months to procure — keeping your facility offline for half a year.

Regular oil filtration is the best practice for ensuring the continued reliability of your Transformers.
Petrozone International can provide Transformer Oil Filtration services throughout Saudi Arabia
To ensure the proper functioning and longevity of transformers, various essential electrical tests must be conducted as part of Annual preventive maintenance.
These tests play a crucial role in assessing the overall health of transformers and include Insulation Resistance (IR), Polarization Index (PI), Turn Turns Ratio (TTR), Winding Resistance (WR), Tan Delta, Short Circuit Impedance, SFRA, DFRA and OLTC Function Test. These assessments are vital for maintaining the optimal performance of transformers and ensuring their reliability over time.
Regular preventive maintenance of transformers involves a comprehensive set of oil tests.
These tests include assessing Breakdown Voltage (BDV), analyzing Dissolved Gases (DGA), measuring Interfacial Tension, evaluating Color, determining Acid Number, conducting Visual Inspections of Oil, performing Water Content Analysis, and measuring Dielectric Dissipation Factor.
These essential tests are crucial for early issue detection and should be conducted on a routine basis.
