摘要： The life of load tap changer contacts is monitored by detecting an arcing event; identifying arcing surfaces involved in the arcing event; calculating a per-unit loss of life for the identified arcing surfaces as a result of the arcing event; updating estimates of cumulative erosion for the arcing surfaces; comparing the updated estimates of cumulative erosion to a first threshold value; and signaling for action when at least one of the updated estimates of cumulative erosion exceeds the first threshold value.
