Leak Detection and Repair in the United States

Pricing varies according to the equipment, leak location, repair method, site requirements, and whether travel or related expenses apply. TDS offers free equipment or substation surveys that identify the facility, equipment, leak location, repair price, and proposed repair method. Customers can then evaluate a targeted solution instead of assuming the cost of full disassembly or traditional regasketing.

Leak detection approaches vary by equipment and application. For TDS projects, technicians may use visual inspection and equipment surveys, oil leak detection methods for transformer components, and infrared laser scanning for environmental monitoring and SF6 gas leaks. The appropriate approach depends on whether the issue involves transformer oil, SF6 gas, a circuit breaker, GIS equipment, or another substation component.

There is no single average cost because repair pricing depends on the equipment, leak location, access, repair design, and site conditions. TDS identifies the precise failure location and provides itemized repair costs through its survey process. Targeted low-pressure sealing may avoid the broader expense associated with draining, dismantling, re-gasketing, and returning equipment to service.

Many TDS repairs can be performed while equipment remains energized and in service when conditions allow. This approach is intended to reduce outage exposure and avoid unnecessary disassembly. The final method depends on the apparatus, leak location, safety requirements, and site assessment. TDS technicians evaluate the equipment and recommend a suitable repair procedure before work begins.

TDS works with transformer oil equipment, SF6 gas-filled circuit breakers, oil circuit breakers, GIS systems, and other electrical substation apparatus. Common repair locations include valve gaskets, drain valves, bushings, flanges, radiator fins, manway covers, mounting connections, and end caps. The company also develops custom sealing solutions for non-traditional leak locations.

Yes. TDS states that it offers free substation or equipment surveys. A survey can document the facility, affected equipment, leak location, proposed repair method, and itemized repair costs. It helps maintenance teams understand the scope before authorizing work and supports a targeted approach rather than automatically planning for equipment removal or traditional re-gasketing.

TDS states that its leak-seal work includes a full four-year leak-seal warranty. Warranty applicability should be reviewed with the company for the specific equipment and repair scope. The warranty statement applies to leak-seal repairs and should not be assumed to cover unrelated equipment conditions, additional leaks, or work outside the agreed repair.

Company information lists service areas as the United States, Canada, and internationally. The service catalog states that work is available for utilities nationwide, while other information notes worldwide availability and representatives across service areas. TDS can review the equipment location, travel requirements, and site conditions when discussing a potential survey or repair project.
