| Transformer Service, Inc. | |
| TSI
was established in 1952, and was one of
the first independent companies to provide
transformer testing, evaluation, field maintenance,
fluid handling & treatment, installation
& disposal and laboratory fluid analytical
services. Our customers include large and
small utilities, industrial plants, commercial
buildings, municipalities, schools, hospitals
and in general any power generator or large
consumer of electric power. Most customers
are located in the eastern half of the US. |
|
TSI has an in-house analytical laboratory, a fleet of mobile fluid purification systems, tank trailers, and maintenance trucks that are fully equipped to provide on-site service and test of transformers and protective equipment. We also have shop facilities for reconditioning transformers, switchgear and circuit breakers, including the ability to un-tank transformers for forensic investigation and repair. TSI also has an EPA regulated Annex III PCB storage facility and the necessary transporter permits to accommodate transportation for disposal of equipment and fluids at any PCB level. TSI provides four types of services: (Please click on a link for more information) |
|
| 1. Fluid Sampling: Transformer insulating fluid is sampled annually. The samples are analyzed using gas chromatographs and spectrometers, and the results of these tests show the types and amounts of contaminants in the oil and how they have changed from year to year. The contaminants are a result of aging, overheating, leaks or other performance problems. A test report with graphics showing trends and maintenance recommendations are sent to the customer. | |
| 2. Field Service and Fluid Purification: Items repaired include bushings, connections, circuit breakers, electrical and electromechanical assemblies, gaskets, pumps, coolers, fans, valves and gauges. Fluid degasification removes moisture, particulate and gaseous contaminants by pumping oil through a vacuum filtration system and. The oil purification process is also used to ensure that all moisture is purged from a transformer during installation or relocation. Fuller’s earth filtration is used to remove acids and sludge to improve interfacial tension (IFT), neutral number, power factor and color. |

Electrical
Test:
Electrical tests accurately measure these
important values:
a. Insulating value of insulation (DC
Megger) Test results are compared to manufacturers specifications and/or performance standards set by NETA, IEEE and NEMA, and establish a baseline for comparison with future tests. Repairs or calibration needed to bring equipment into specification can be easily identified, and post repair testing assures that proper corrective action has been taken. In
many cases, testing identifies the need
for preventive maintenance and adjustments
that preclude costly repairs, downtime
and failures in the future. |
 |
| 4. Installation, Removal and Disposal: TSI specifies and procures replacement transformers, removes and disposes of the customer’s old transformers, and installs the replacement transformers. Replaced equipment (regardless of PCB level) is transported and disposed of in accordance with local, state and EPA regulations. | |
