Long Term Programs (LTP) - Siemens· PDF filePower transformers usually perform their work, humming quietly for dec-ades without any interruption. Owners have thus come to rely on their safe transformer capacity, often performing only minimal maintenance using tradi-tional and reckoned techniques. Worldwide around over 70% of trans-formers have been in service for more than 25 years.
