PCB-3 Module For Parallel Of Generators Didactic Equipment Electrical Engineering Lab Equipment
The module it enables to learn and experiment, with real industrial components. TRAINING PROGRAM: The training concerns the study of the instruments andtechniques for MANUAL or AUTO parallel connection of thealternators to the mains. Main treated subjects: • regulation of the prime mover in order to generate a triad ofcompatible voltage for the parallel with the line power • determination of the parallel device closing in MAN/AUTOmodes • synchronous machines in parallel between them and withthe line power • overload of the synchronous machines and loss of the parallel
TECHNICAL SPECIFICATION: The structure is made in sheet steel chemically treated andpainted with epoxy paint; the base is provided with rubber feetand can be laid over a work plane. All electrical componentsnecessary for the board operation are included in the module. Main installed components: • 1 Thermomagnetic E.L.C.B. In = 16 A Idn = 30 mA, type A,with minimum voltage trip device and stop emergencypushbutton with mechanical interlock. • 3 Single-phase output sockets for power supply of the powergeneration panels and different accessories. • 1 Double 500-Vac voltmeter for the comparison of thevoltages of both voltages to be set in parallel. • 1 Double frequency meter (45-55-65 Hz, 500 Vac) for thecomparison of both frequencies to be set in parallel. • 1 Syncronoscope, microprocessor controlled type, withsynchronizing relay. Includes: 18 LEDs, two colors, withincreased resolution closer to the synchronization speeds. Suitable for lines 3 x 400 V-50/60 Hz. With programmablevoltage difference (1 to 10%), frequencies difference (2to 20 electrical degrees) and delay time (0.1 to 1sec) forsynchronizing. • 1 Three-lamp sequence indicator for 400-V voltage. • 2 contactors, 25 A AC3, with stop and run pushbuttons. • 1 Three-pole T.M.C.B. In adjustable from 2.4 to 4 A • 1 4-pole E.L.C.B. In = 25 A Idn = 30 mA. • 1 Digital electrical power analyzer to be used with balancedor unbalanced systems with neutral, for measurement ofvoltages, currents, active, reactive and apparent power,peaks of maximum active, reactive and apparent power,active and reactive power counting, cogeneration counters. The analyzer includes a wide, high contrast, LCD display,five languages menu, organized in pages. Four pages canbe programmed for a quick visualization of the preferredparameters. Complete with two programmable relays (forany parameter selected among any of the measured ones)with maximum and minimum alarm functions. The analyzer is provided with an interface RS485 for data acquisition withPersonal Computer. • 1 RS485/USB Converter and software for data acquistionwith personal computer. Power supply: 230 Vca 50 Hz single-phase - 3 kVA(Other voltage and frequency on request) Dimensions: 840 x 450 x 680 mm Weight: 38 kg Supply with THEORETICAL – EXPERIMENTAL HANDBOOK
