MG Transformer Services & Supplies

Maintain the optimal condition of your transformer oil and extend its lifespan with our professional Transformer Oil Filtration Services. We offer both on-site and online/offline filtration options to remove contaminants and moisture, ensuring peak transformer performance and reliability.

Our Filtration Services:

• On-Site Filtration: Our mobile filtration units are equipped to handle various transformer sizes and oil volumes. We perform filtration directly at your location, minimizing downtime and disruption to your operations.
• Online Filtration: For continuous oil purification during transformer operation, we offer online filtration systems that remove contaminants without interrupting power supply.
• Offline Filtration: For periodic oil maintenance or when the transformer is offline, we provide offline filtration services to restore oil quality and remove accumulated contaminants.

Enhance the performance, lifespan, and operational comfort of your dry-type transformer with our specialized Core Varnish Treatment. We apply a premium, insulating varnish to the transformer core, delivering a trifecta of benefits: noise reduction, insulation upgrade, and core protection.

Benefits of Core Varnish Treatment:

• Noise Reduction: The varnish coating dampens core vibrations, significantly reducing operational noise levels, creating a quieter working environment.
• Insulation Upgrade: The varnish acts as an additional insulating layer, enhancing the core's dielectric strength and minimizing the risk of electrical breakdown or short circuits.
• Core Protection: The varnish shields the core from moisture, dust, and other environmental contaminants, preventing corrosion and extending its lifespan

Extend the life of your transformers with expert assessment. Comprehensive diagnostic services to evaluate the health and remaining lifespan of your power transformers. Utilizing advanced techniques like Tan Delta & Capacitance, SFRA (Sweep Frequency Response Analysis), and more, we provide actionable insights for informed maintenance and replacement decisions.
