TRANSFORMER MONITORING FUNCTIONS
The transformer monitoring functions provide monitoring and alarms for the transformer to help manage
equipment inspection and maintenance expenses. Transformer monitoring functions include through-fault
counter reporting and through-fault current duty monitoring. Each of these functions can be set as a
programmable alarm. See the paragraphs on Alarms Function, later in this section for more information
on the use of programmable alarms.
