TDS provides transformer and circuit breaker leak sealing solutions around the world. Our proven experience and commitment to excellent customer service has made us the leak sealing company of choice for the power industry.

TDS is the only company in the world that specializes in substation leak sealing. TDS devotes 100% of their time to the repair of transformer oil and SF6 gas leaks with over 15 years of work dedicated to the electrical utility industry. Our representatives, technicians, and management only work in substations and are extremely knowledgeable about leak sealing on transformers and circuit breakers.

Our leak sealing techniques are designed to repair oil and SF6 gas leaks on energized equipment whenever possible. This results in substantial cost savings over traditional repair methods that require expensive equipment outages. TDS leak repair techniques also provide maximum flexibility to Utility Asset Managers when making decisions on replacing or refurbishing equipment.

TDS personnel “walk the walk”. We ask customers to provide us with some leak concerns so that we can field demonstrate our leak repair methods. This allows utility personnel to physically observe leak sealing in action. This sample work is performed at no risk to the customer. If TDS doesn’t fix the leak, the customer doesn’t pay.

Take advantage of our Free Substation Survey. Our representatives will review your leak sealing requirements, providing documentation of the leaks and proposed TDS repair methods. This not only allows utility management to develop an “action plan” to address leaks, but is also effective at showing regulatory agencies like the EPA that utility management has “their arms around the problem”.

Our commitment is to maintain your trust and confidence through superior performance and service. For cost-effective and comprehensive management over oil and SF6 gas leaks at your facility.

TRANSFORMER OIL LEAK DETECTION
Effective repair of transformer oil leaks begins with determining the exact component that is leaking. Visual inspection of the oil leak location is often inadequate. Click the link below for details on how TDS personnel will pinpoint the exact piece of equipment that is leaking allowing us to concentrate our efforts in that location.

Transformer Leak Repair Procedure: Oil Leak Detection.

TRANSFORMER OIL FLOW CONTROL VALVE LEAKS
Many transformer oil leaks are associated with the failure of gaskets on flapper and butterfly valves controlling the flow of oil between the radiator and main oil tank. Deterioration of the packing on flapper and butterfly valve stems can also be a source of oil leakage. Additional bolt tightening rarely stops the oil leak.

See how TDS technicians can repair transformer oil leaks associated with oil flow control valves. In most cases, repairs can be accomplished within hours, without expensive downtime required to drain oil from the cooling system.

OTHER SOURCES OF TRANSFORMER OIL LEAKS
Numerous other locations on power transformers are prone to oil leaks due to penetration of bolts and threaded connections typical of Temperature Probes, Liquid Level Gauges, Flow Gauges, No-load Tap Changers. TDS repair techniques are effective in addressing these types of leaks also.
