Maintenance

 

product-794-875

Routine maintenance is critical to guarantee stable operation and extend the service life of the 2500kVA distribution step down transformer. Key maintenance tasks include regular checks on insulating oil quality and oil level, together with winding insulation resistance and voltage tests. The oil tank shall be cleaned periodically, and insulating oil purified to eliminate moisture and impurities. Operators need to inspect grounding circuits and all connection terminals to avoid loose contacts and corrosion. Regular visual examinations and functional checks of the cooling system are also required. Standardized maintenance safeguards reliable long-term performance.
