PCB-2 Module For Parallel Of Generators Teaching Equipment Electrical Engineering Lab Equipment
The module it enables to learn and test the methodology for paralleling alternators, with actual industrial components. TRAINING PROGRAM: Training refers to the study of instruments and techniques forconnecting alternators in parallel with one another and withthe mains. The range of application of these devices is relatedto both big high-voltage power plants and to small autonomousand/or low-voltage co-generation plants. Main subjects dealt with: • regulation of prime mover to generate a compatible set ofthree voltages for the parallel with the mains, • determination of the closing moment of the parallel device, • synchronous machines in parallel with one another and withthe mains, • overload and loss of parallel of synchronous machines. TECHNICAL CHARACTERISTICS: Framework is made of chemically treated sheet steel, paintedwith many epoxy coats; the base is provided with rubber feetand it enables to couple the machines in a very quick way. Allthe necessary electric components for the proper operation ofthe module are included in the panel. Main installed components: • 1 differential automatic magneto-thermal switch ln =10 A ldn= 30 mA, A-type, with minimum-voltage releasing device andemergency pushbutton with mechanical holding • Single-phase output sockets for powering the powergeneration panels and various accessories. • Double 500-Vac voltmeter for comparing the sets of threevoltages having to be paralleled. • Double 45-65 Hz (400 Vac) frequency-meter for comparingthe frequencies of the sets of three voltages having to beparalleled. • 1 LED synchronoscope of 400 V, 50-60 Hz. • 1 three-lamp sequence indicator for voltage of 400 V • Electromagnetic contactors of 25 A AC3, provided with startstop buttons. • 1 three-pole magneto-thermal automatic switch adjustablebetween 2.4 and 4 A • 1 four-pole differential automatic switch In = 25 A Idn = 30mA, A type. • 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. Power supply: 230 Vac 50 Hz single-phase - 3 kVA (Other voltage and frequency on request) Dimensions: 840 x 450 x 680 mm Net weight: 38 kg Supply with THEORETICAL – EXPERIMENTAL HANDBOOK
