Droop CT in Alternators
Droop CT in Alternators
(OP)
Can any body suggest me what is the Use of DRoop CT in ALternators and What should be the Ratio.

RE: Droop CT in Alternators
Voltage droop is load depended (mostly linear); the more load, the less voltage.
The rating is normally specified by the AVR manufacturer.
Furthermore it's common use for generator manufacturers to lead only one pole winding through the primary side of the CT. Thanks to this a physical smaller CT can be selected.
A generator doesn't need a droop CT if it has to run in island operation only.
For a detailed explanation you just have to read the replies on the thread "Droop Setting for Governors"

and search for "droop" literature and schematics.

CT primary is usually chosen as the next standard rating above generator full load current, secondary to match AVR (1A or 5A). It is normally a metering class CT, placed in the generator B phase (or S, depending on practice)lead.

It goes without saying that the manufacturer's schematic diagram must be consulted in designing the installation.
