Thermal Monitor Reset Functions (THE R, THE C, and THE P Commands)
The THE R and THE C (Reset/Clear Thermal Archives Functions) commands
clear all the thermal archives (daily profile data, hourly profile data, and thermal
event data) and resets the total accumulated loss-of-life value to its preset value
(if it exists) or zero.
Using the THE P n (Load Preset Value of Total Loss of Life) command, the user
can preset the initial loss-of-life values for each phase of the monitored trans-
former. The command must be followed by a value between zero and 100 per-
cent. This command initializes the total loss-of-life value to the preset value
entered by the user and restarts the thermal element. Thermal archive data are not
cleared.
