Case study on increasing the transport capacity of 220 kV DC OHL Iernut-Baia Mare by reconductoring using LM technologies

In 2009 we have celebrated 30 years since the first live maintenance techniques (LMT) have been carried out in Romania. This paper, in acknowledgement of the Romanian Live Maintenance Association's valuable activity in this field, is tackling a major issue for the Romanian Power Grid Company Transelectrica S.A.: the increase of the overhead line transmission capacity applying reconductoring with high temperature low sag (HTLS) conductors. The authors are proposing the use of live maintenance techniques, which considerably reduce the overhead line unavailability.
