3 CONFIGURATION AND SCOPE OF SUPPLY GENERAL The generator is designed to operate together with a diesel or gas engine. CONSTRUCTION The stator frame is a rigid welded steel structure construction. The stator core is built of thin electric sheet steel laminations which are insulated on both sides with heat-resistant inorganic resin. The rotor consists of a shaft and a star shape rotor core. The shaft is machined of rolled steel. Special heat treatment is used if shaft operates under heavy conditions. The poles are manufactured of. mm sheet steel. The pole laminations are pressed and welded together with steel bars. These bars are then welded to the end plates. Rotor balancing is done acc. to ISO 194/1. The standard balancing quality grade is G2.. All windings are completely vacuum pressure impregnated with high quality resin. The windings are provided with very strong bracing which withstands all expected mechanical and electrical shocks and vibrations as well as chemicals. End shields are made of casted steel, The stator frame and stator core are welded together, and bolted with end shields MAIN TERMINAL SPACE Protection class IP44, Integrated into the top module of the generator. Supply cable entries: Closed terminal box. Cable inlet to the main terminal box to be done by the customer. Twelve (12) leads T1 T12 brought into the terminal box to enable internal series star, parallel star, series delta and parallel delta connection, Main terminals U, V, W and neutral point N in the main terminal box for external connection Terminal marking acc. to IEC. Designed for continuous current load. FOUNDATION The machine can be mounted using shimming, machined blocks, chock fast or on grouted sole plates or bed plate. Before using other mountings, contact us. CONTROL SYSTEMS General Brushless excitation. Automatic Voltage Regulator System Mounted inside the main terminal box. Analog type AVR. Functions: a) 1-channel AVR. b) Excitation power can be from phase voltage of main terminal or auxiliary winding. c) Voltage set-point adjustment (local). d) U/f limiter. e) Parallel operation.
