Importance of Transformer Oil Maintenance and Purification
Transformers represent vital assets within electrical distribution networks. Moisture contamination, dissolved gases, and sludge particles inside transformer oil reduce dielectric strength. Such conditions risk internal short circuits and permanent damage to transformer windings.
Oil purification and treatment processes from PT Sentra Elektrikal Prima separate moisture, gases, and solid impurities using high-temperature vacuum circulation. This procedure extends transformer operational life and prevents unexpected system failures.
Scope of Transformer Maintenance and Testing Services
Our transformer maintenance services include comprehensive technical testing procedures:
- Breakdown Voltage (BDV) Testing: Measuring dielectric breakdown voltage of insulating oil per standard testing procedures.
- Moisture Content Testing (Karl Fischer Titration): Measuring micro-level moisture content inside transformer oil with precision.
- Thermovision Inspection (Thermal Imaging): Detecting abnormal temperature rises on bushings, connection terminals, and transformer tanks.
- Insulation Resistance Testing: Testing insulation quality of primary and secondary windings using specialized measurement instruments.
- Oil Treatment & Purification (Filtering, Degassing, Dehydrating): Filtering solid particles, removing dissolved gases, and dehydrating moisture from transformer oil.
Reference Standards & Industrial Equipment
All testing and purification procedures performed by PT Sentra Elektrikal Prima adhere to international standards:
- Breakdown Voltage Standard: Compliant with IEC 60156 (Insulating liquids - Determination of the breakdown voltage at power frequency).
- Insulating Oil Quality Standard: Compliant with IEC 60422 (Fluids for electrotechnical applications - Supervision and maintenance guide for mineral insulating oils in electrical equipment).
- High-Precision Equipment: Operating high-capacity vacuum Oil Purifier machines alongside calibrated Megger Insulation Testers.
