PATH: SETTINGS GROUPED ELEMENTS
TRANSFORMER
This menu contains the settings for the transformer differential elements and the transformer thermal elements.
The thermal elements include hottest-spot temperature, aging factor and loss of life. The computation of these elements fol-
lows IEEE standards C57.91-1995: "IEEE Guide for Loading Mineral-Oil-Immersed Transformers" and C57.96-1989: "IEEE
Guide for Loading Dry-Type Distribution Transformers". The computations are based on transformer loading conditions,
ambient temperature, and the entered transformer data.
