Load Tap Changer (LTC) Maintenance

For units with LTCs, the LTC is the key component and, without proper maintenance, can be a leading cause of failure. GE can evaluate the condition of your LTC by sampling oil from the energized transformer. Test results indicate what type of maintenance needs to be performed offline, minimizing downtime. Our services include:

  • Complete internal inspection and contact or interrupter replacement
  • Maintenance to original equipment manufacturer (OEM) specifications
  • Rebuild and repair
  • Validation of alarms and protective devices
  • Upgrade of obsolete electro-mechanical controls with modern solid state controls
