ABSTRACT
Focus of 3PINT project is to upgrade readiness level of the innovative technology for the removal of corrosive sulphur, PCB and aging product from transformer oils. Technology itself includes chemical conversion process to refine transformer oils in eco-frendly manner. Used technology is environmentally closed with no toxic emissions and waste released into environment. In addition, innovative solution for corroded silver-plated contacts cleaning, effectively removes silver sulphide deposits from OLTC contacts, ensuring long-term reliability and complete power transformer corrosive sulphur mitigation.
Keywords: 3PINT, innovative technology, environmentally closed technology, power transformer, complete corrosive sulphur mitigation
