These brands, however, do not encompass our full range of capabilities: we can work on almost any transformer, performing repairs as listed below:

Radiator and Cooler Replacement

With ATS engineering expertise combined with high quality suppliers, we can provide replacement radiator and/or cooler packages ready to install. Installation packages can include; installation drawings, radiators/coolers, pumps, piping, gaskets and hardware, or any combination of these items. In addition to supplying the parts, ATS can field install the equipment. If specifications and/or drawings are not available a technician/engineer can make a site visit to acquire any necessary dimensions and information.

Bushing Replacement

ATS has relationships with most bushing suppliers/manufactures allowing us to acquire a direct replacement bushing or determine an acceptable replacement for bushings that are obsolete and no longer manufactured. If modifications to leads and/or connections to accommodate dimensional differences are nessecary they can be identified and adapter leads and/or connections can be made during installation. Complete installation service may include oil handling, lead modification (if necessary), vacuum fill (if required) and testing. If information on the bushing requiring replacement is unavailable, a ATS technician/engineer can make a site visit to acquire any needed dimensions and/or equipment information.

Gauge Replacement and Calibration

In addition to replacing existing gauges, ATS can add gauges to transformers originally supplied without gauges, and/or provide complete monitoring systems. Scope(s) of work can include supplying new or replacement gauges, mounting gauges on tank, running line for temperature probe(s), modifying tank to add probe(s), wiring from the control box to gauges, calibrating the equipment and verifying operation.

Leak Repair

Oil and nitrogen leaks are costly and often occur due to extreme operating and environmental conditions, leaks can occur at gaskets, fittings, welds and points of physical damage. Most leaks are repairable, ATS has the ability to find leaks and make repairs. Some of our resources include experienced personnel; equipment necessary to handle the project, store oil and vacuum-fill; certified, experienced welders and specialized procedures.

In addition to transformer repairs,  ATS has the equipment, experience and capability to complete upgrades, insulation dryouts, LTC repairs/upgrades, and FR3 retrofills.  These are but a few services we preform, please call or email for a complete list.
