5.26 78VS Voltage Vector Shift
of the 78 pickup setting. A setting of 6° is recommended by the G.59 standard for connection of distributed
generation to an electricity supply system, and settings of 8° to 12° are typical.
When the exported power to the mains network is very low, there is a risk that the drop in load will be insuffi-
cient to cause a vector shift, or will cause a vector shift of limited extent. Generally it is required that exported
power will be of the order of 10 % to 20 % of total power generated before a LOM will always be detected.
