Circulating current and delta VAR methods
The user with access to the Configuration Menu may select the circulating current method
of paralleling LTC transformers, or disable the feature. If the optional ΔVAR®1/ΔVAR2
methods were purchased, they may also be selected. Paralleling by the circulating current
