Period

THIS GENERATOR USED 1899-1963.

Canada

ONE OF 1ST AC GENERATORS USED AT ADAMS STATION POWERHOUSE NO. 1, THE FIRST POWERHOUSE BUILT AT NIAGARA BY THE NIAGARA POWER CO., WHICH ALSO OWNED THE CANADIAN NIAGARA POWER CO.. THIS GENERATOR WAS PRODUCED IN 1898 AND INSTALLED AS GENERATOR NO. 6 (OF 10) ON JAN 11, 1899. DONATED TO OH BY ADAMS STATION IN 1964 (REF. 1)

Function

TO CONVERT ROTARY MECHANICAL ENERGY INTO AC ELECTRICAL ENERGY.

Technical

ONE OF 1ST AC GENERATORS PRODUCED BY WESTINGHOUSE ESPECIALLY FOR ADAMS POWER STATION IN NIAGARA FALLS, NY. CHARACTERIZED BY LOWER IRON LOSS & MORE VENTILATING PASSAGES IN BOTH ARMATURE & FIELD; FITTED WITH VERTICAL WATER-COOLING PASSAGES CORED IN THE CAST-IRON SPIDER, IN WHICH THE ARMATURE LAMINAS WERE DOVETAILED. THE ARMATURE CONDUCTORS, MADE OF COPPER, WERE 2 INCHES BY 7/32 INCH, WITH ROUNDED CORNERS, MICA INSULATED, AND MOUNTED ONE IN EACH OF 322 SEPARATE SLOTS. THE WINDINGS OF TWO PHASES WERE ELECTRICALLY INDEPENDENT, AND ALL THE CONDUCTORS WERE ARRANGED IN SERIES. THE MAGNETIC DENSITY OF THE CONDUCTORS WAS INCREASED BY 15%. THE ARMATURE WAS WOUND AT THE WESTINGHOUSE FACTORY IN EAST PITTSBURGH AND NOT IN THE POWERHOUSE, AS IN THE CASE OF PREVIOUSLY INSTALLED DYNAMOS. THE GENERATOR HAS A HIGH RATIO OF ARMATURE TO FIELD AMPERE TURNS; THE AIR GAP WAS SHORTENED FROM ONE INCH TO THREE-QUARTERS. IT REQUIRED A 50% INCREASE OF THE NO LOAD EXCITING CURRENT TO MAINTAIN THE SAME POTENTIAL DIFFERENCE BETWEEN TERMINALS WITH A NON INDUCTIVE RATED LOAD. THE MACHINE GAVE ABOUT TWICE THE FULL-LOAD CURRENT ON THE DEAD SHORT CIRCUIT. (Ref. 1)
