/ˌəʊvəkəmˈpaʊnd/, U.S.

/ˈˌoʊvərkəmˈpaʊnd/

Origin: Formed within English, by derivation. Etymons: over- prefix, compound v.

Etymology: < over- prefix + compound v. Compare slightly earlier over-compounded adj., overcompounding n.

Electrical Engineering.

transitive. To provide (a dynamo) with so many series turns (compared with the number of shunt turns) that the voltage which is generated increases as the load increases. Also (occasionally) intransitive.

1896 S. P. Thompson Dynamo-electric Machinery (ed. 5) 237 By over-compounding, one can obtain a constant pressure, not at the terminals of the dynamo, but on the mains at some point in the midst of the lamp-network.

1914 A. Gray Princ. & Pract. Electr. Engin. xiii. 75 For railway service the generators are overcompounded so as to maintain the trolley voltage at some distance from the power house.

1937 H. E. Stafford Troubles of Electr. Equipm. iii. 46 To over~compound a generator not provided with diverters, the only permanent way is to increase the strength of the series and interpole fields.
