PCB-3 Module For Parallel Of Generators Didactic Equipment Electrical Engineering Lab Equipment
Description
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 and techniques for MANUAL or AUTO parallel connection of the alternators to the mains.
Main treated subjects:
• regulation of the prime mover in order to generate a triad of compatible voltage for the parallel with the line power
• determination of the parallel device closing in MAN/AUTO modes
• synchronous machines in parallel between them and with the line power
• overload of the synchronous machines and loss of the parallel

TECHNICAL SPECIFICATION:
The structure is made in sheet steel chemically treated and painted with epoxy paint; the base is provided with rubber feet and can be laid over a work plane. All electrical components necessary 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 emergency pushbutton with mechanical interlock.
• 3 Single-phase output sockets for power supply of the power generation panels and different accessories.
• 1 Double 500-Vac voltmeter for the comparison of the voltages of both voltages to be set in parallel.
• 1 Double frequency meter (45-55-65 Hz, 500 Vac) for the comparison of both frequencies to be set in parallel.
• 1 Syncronoscope, microprocessor controlled type, with synchronizing relay. Includes: 18 LEDs, two colors, with increased resolution closer to the synchronization speeds.
Suitable for lines 3 x 400 V-50/60 Hz. With programmable voltage difference (1 to 10%), frequencies difference (2 to 20 electrical degrees) and delay time (0.1 to 1sec) for synchronizing.
• 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 balanced or unbalanced systems with neutral, for measurement of voltages, 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 can be programmed for a quick visualization of the preferred parameters. Complete with two programmable relays (for any 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 with Personal Computer.
• 1 RS485/USB Converter and software for data acquistion with personal computer.
