Load Tap Changer (LTC)
66电玩城注册送60000金币We defined the standards for high quality and reliable load tap changer overhauls/upgrades, starting with our industry-leading conversion and overhaul of the GE LRT200 in 1994. This overhaul and the many years of experience gained since then have given SPX Transformer Solutions the knowledge and expertise to develop thorough and comprehensive LTC refurbishment programs for a variety of LTC models.
The first and most important step in the LTC rebuild process is a thorough inspection to document the condition of the load tap changer as received and to determine the most probable failure mode(s). Following this initial inspection, the entire mechanism is completely disassembled and all parts physically evaluated for wear condition and failure damage, including hi-pot and wear evaluation of vacuum interrupters (if present). Scope of work is then defined detailing all parts to be reused and new parts needed to complete the overhaul/upgrade. A final repair report detailing all items replaced/reused and a failure analysis showing “as received” condition and mode of failure is available upon request.
