LOSS OF LIFE
The Loss of Life element detects the accumulated total consumed transformer life. This element can be set to issue an
alarm or trip when the actual accumulated transformer life becomes larger than the user-specified loss of life pickup value.
For new transformers installations, the
XFMR INITIAL LOSS OF LIFE
setting should be “0”. For previously installed transform-
ers, the user should pre-determine the consumed transformer life in hours.
• LOSS OF LIFE INITIAL VALUE : Enter a setting for the consumed transformer life in hours. When the Loss of Life ele-
ment is enabled, the computed loss of life will be added to the initial loss of life.
• LOSS OF LIFE PICKUP : Enter the expended life, in hours, required for operation of the element. This setting should
be above the total transformer life set as a reference based on nominal loading conditions and a 30°C ambient temper-
ature, as outlined in the IEEE standards.
