Load Tap Changer (LTC) Maintenance

PT. TRANFEXCO Indonesia has the ability and expertise to service Load Tap Changers.

We can perform a condition assessment of your LTCs to advise what is wrong or what can be done to increase reliability and extend the life of this important asset.

We 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!

PT. TRANFEXCO Indonesia 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.

To keep your Load Tap Changer operating properly, PT. TRANFEXCO Indonesia 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, PT. TRANFEXCO Indonesia can provide and install maintenance-saving devices such as Oil Filtration Systems and ARDBs (Auto-Recharging Dehydrating Breathers)

Transformer Oil Processing

PT. TRANFEXCO Indonesia is ready to respond when your transformer is ready for oil. An experienced team of Field Service Technicians and Service Project Managers are available with the latest equipment and tools to handle your oil processing needs:

• Drain Oil from Transformer/ Equipment
• Store Oil On-Site in Tank or flexi bag (either your tank or ours)
• Pull Vacuum on Transformer (to your specifications or ours)

Oil Reclamation

Remove contaminants, sludge, foreign particles, dissolved gasses and oil decaying byproducts contained in the oil. The heat from the energized transformer aids in dissolving sludge buildup and removing moisture from the insulation. Thus, the customer has a clean transformer with excellent oil properties.
