One of our company trucks with spill containment will pick your transformers up. Our fleet is highly trained and experienced at hauling transformers.

Upon arrival at NETS factory all nameplate data is catalogued and each piece of equipment is barcoded for electronic tracking through the facility.

After cataloging the transformer moves to disassembly. It is first given a preliminary evaluation of defects; Tank Corrosion, Broken Parts, Oil Leaks, Damaged Tank, Out of Date Design. The transformer is then opened, pumped, and completely disassembled. Each major component of the transformer transfers to a separate area in the factory to be processed.

The tank will undergo any repairs or conversions necessary in a weld station. After passing inspection it moves on to be shot blasted in preparation of paint.

All units are coated using paint that meets ANSI/IEEE Polemount Enclosure Integrity standard.

The Core/Coil undergoes several low voltage tests and a thorough quality assurance inspection. Parts conversion to update the coil to newer standards will also be performed. After passing inspection the Core/Coil is processed in NETS proprietary coil dry-out system that rejuvenates the coil and removes moisture, gasses, and particulates.

All parts are fully disassembled, inspected, and cleaned or replaced. Any parts not meeting customer standards will be replaced to meet modern design. New gaskets are installed.

All insulating fluid is reprocessed to remove gasses, moisture, particulates and acidity.

The final product meets ANSI/IEEE standards for Dissolved Gas Analysis, Dielectric Strength, Moisture Content, Acidity, and Color.

Once all 4 major components are processed, all items re-unite in final assembly.

After assembly the transformer will undergo a series of inspections and low voltage testing to assure quality of the previous steps. After passing test it will be filled with hot oil under vacuum to remove any air pockets from the windings that might cause dielectric failure.

After being oiled and sealed all units undergo a 6 PSI pressure test to check for leaks.

All transformers then move to Final Test to receive a full factory test per ANSI/IEEE.

NETS does not perform routine testing, we factory test every single unit.

After passing test all external accessories are installed and the unit is banded to a new pallet.

Mandatory safety labels, customer identification labels, and a new NETS nameplate are installed.

After undergoing the highest quality rebuild in the industry, the previously obsoleted and damaged transformer now awaits return to customer for half the cost of purchasing a new transformer.
