Waukesha Service has the ability and expertise to service most Load Tap Changers in use today in the United States. We can perform a condition assessment of your LTC(s) to advise what is wrong or what can be done to increase reliability and extend the life of this important asset. High Voltage Supply, our division in Dallas, TX, can provide a complete parts kit so when we service an LTC, we have the correct parts at the jobsite to promptly repair the unit rather than waiting for parts to arrive to complete the job. This process can save time and money! Waukesha Service also has the necessary equipment and manpower to remove the oil to perform an in-tank LTC inspection and either clean, or more typically, replace the LTC oil.

Load Tap Changer MaintenanceTo keep your LTC operating properly, Waukesha Service can make necessary repairs or adjustments:

  • Replace old or worn gaskets
  • Fix leaks
  • Replace contacts, check alignment and timing
  • Provide and replace phase moldings and tap heads
  • Replace the complete internal operating mechanisms on some models of tap changers
  • Check the regulating relays for proper operation

Proper LTC oil maintenance can reduce arcing times and extend contact life. To keep your LTC oil clean and dry, Waukesha can provide and install maintenance-saving devices such as Oil Filtration Systems and ARDBs (Auto-Recharging Dehydrating Breathers).

Comprehensive LTC maintenance training is available through High Voltage Supply. Classes are scheduled regionally throughout the year for several of the most common models of tap changers in operation today. Experienced instructors also offer LTC training at our High Intensity Training facility in Dallas, TX. Training can also be scheduled at your facility if that's most convenient and cost-effective for you. For more information on these training classes, click here to visit our HVS training page.

Do you have older transformers with reactive bridging LTCs that are way past their prime?

Is your equipment unreliable and giving you a “big time” maintenance headache?

Waukesha Service is the team to call! We can replace that old reactive-bridging Tap Changer with a new reactive-bridging, vacuum-arcing style LTC to help improve transformer reliability, reduce maintenance costs, and extend the life of your assets. Your Waukesha Service Project Engineer and Field Service Technician can handle the project, turnkey, including:

  • Draining the oil from your transformer and LTC
  • Disconnecting and cutting the old LTC away
  • Modifying the Preventive Auto (if necessary)
  • Fabricating a transition cubical
  • Supplying a new Reinhausen Type RMV-II Load Tap Changer
  • Mounting the RMV-II onto your transformer

Our experienced crews will also modify the control wiring as necessary and can upgrade to a new Regulating Relay so that the new LTC will function as expected.

Bare metal will be primed and painted so the job looks like new, and following vacuum filling, the transformer and LTC will be retested to check for proper operation.

Comprehensive LTC maintenance training is available through High Voltage Supply. Experienced instructors at our High Intensity Training facility in Dallas, TX offer classes throughout the year, including regional classes on a variety of LTCs. Training can also be scheduled at your facility if that's most convenient and cost-effective for you. Click here for a current LTC training schedule and links to more information.
