  5. INTRODUCTION ISTITUTO TECNICO INDUSTRIALE STATALE “ALESSANDRO VOLTA” NAPOLI DG Education and Culture Leonardo da Vinci PARTNERSHIPS

  6. INTRODUCTION I.T.I.S. A. Volta-Napoli IN ITALY THE TEACHING OF "ELECTRICAL MEASUREMENT" AS PART OF THE CURRICULUM OF STUDIES " INDUSTRIAL EXPERT - ELECTRICAL AND AUTOMATION SPECIALIZAZTION" IS NO LONGER AN AUTONOMUS SUBJECT. THE SUBJECT’ S CONTENT IS PART OF “ELECTRICAL ENGINEERING” INCLUDING LABORATORY HOURS DURING WHICH STUDENTS ARE TESTED THROUGH EXERCISES.

  7. INTRODUCTION I.T.I.S. A. Volta-Napoli IN PARTICULAR THE SUBJECT "AUTOMATIC ELECTRIC SYSTEMS", HAS BEEN INTRODUCED, WHICH MOREOVER, HAS THE TASK OF CREATING A SYNTHESIS BETWEEN THE ACQUIRED KNOWLEDGE DURING THE ENTIRE COURSE OF STUDY, INCLUDING A CONTINUOUS LINK WITH OTHER DISCIPLINES, FIRST OF ALL ELECTRICAL AND ELECTRONICS ENGINEERING COMPUTING.

  8. INTRODUCTION I.T.I.S. A. Volta-Napoli ON THE STRENGTH OF THESE INNOVATIONS, EVEN "ELECTRICAL MEASUREMENT“ TEACHING HAS EXPERIENCED AN UPGRADE, INTRODUCING ELEMENTS OF ELECTRONICS AND COMPUTERS. HERE BELOW YOU CAN SEE AN EXAMPLE OF A "MEASURES EXERCISE "

  9. EDUCATIONAL OBJECTIVES OF THE MEASURE ISTITUTO TECNICO INDUSTRIALE STATALE “ALESSANDRO VOLTA” NAPOLI DG Education and Culture Leonardo da Vinci PARTNERSHIPS

  10. EDUCATIONAL OBJECTIVES OF THE MEASURE I.T.I.S. A. Volta-Napoli AT THE END OF THE EXERCISE STUDENTS WILL: • GAIN AWARENESS OF THE CONDUCT OF SIMPLE AC CIRCUITS AND OF THE PHENOMENON OF RESONANCE • ACQUIRE THE ABILITY TO INTEGRATE KNOWLEDGE OF THE FOLLOWING DISCIPLINES: • ELECTRIC MEASURES • ELECTRONICS • AUTOMATIC SYSTEMS

  11. PREREQUISITES ISTITUTO TECNICO INDUSTRIALE STATALE “ALESSANDRO VOLTA” NAPOLI DG Education and Culture Leonardo da Vinci PARTNERSHIPS

  12. PREREQUISITES I.T.I.S. A. Volta-Napoli PUPILS SHOULD KNOW: • BASIC PRINCIPLES OF ALTERNATING CURRENT; • BASIC PRINCIPLES OF ELECTRICAL MEASUREMENT (MEASURES); • SOFTWARE USUALLY USED IN A PC; • SOFTWARE MICROSOFT EXCEL.

  13. DESCRIPTION OF THE EXERCISE ISTITUTO TECNICO INDUSTRIALE STATALE “ALESSANDRO VOLTA” NAPOLI DG Education and Culture Leonardo da Vinci PARTNERSHIPS

  14. DESCRIPTION OF THE EXERCISE I.T.I.S. A. Volta-Napoli THE EXERCISE PLANS TO MAKE A SERIES OF CURRENT MEASUREMENT IN ORDER TO DESCRIBE THE CONDUCT OF A A.C. CIRCUIT WHEN POWER FREQUENCY CHANGES. THE RESULTS ARE INPUTTED ON A PERSONAL COMPUTER, AND TRASFERRED THROUGH FILE TO THE SOFTWARE EXCEL FOR GRAPHIC AND ANALYTICAL PROCESSING OF DATA.

  15. DESCRIPTION OF THE EXERCISE I.T.I.S. A. Volta-Napoli STEP OF WORK: 1 - DIRECT MEASUREMENT OF CURRENT IN A SERIES RLC CIRCUIT POWERED WITH VARIABLE FREQUENCY 2 - TRANSFER OF DIGITAL DATA MEASURED BY A DIGITAL MULTIMETRO ON A PERSONAL COMPUTER 3 - ANALYSIS OF THE BEHAVIOUR OF COMPONENTS AND CIRCUIT THROUGH AN EXCEL SPREADSHEET.

  16. DESCRIPTION OF THE EXERCISE I.T.I.S. A. Volta-Napoli THE FOLLOWING FIGURE SHOWS THE SETUP CIRCUIT. Figure 1

  17. COMPONENTS AND INSTRUMENTS ISTITUTO TECNICO INDUSTRIALE STATALE “ALESSANDRO VOLTA” NAPOLI DG Education and Culture Leonardo da Vinci PARTNERSHIPS

  21. COMPONENTS AND INSTRUMENTS I.T.I.S. A. Volta-Napoli DIGITAL MULTIMETER: DATASHEET MULTIMETER

  22. COMPONENTS AND INSTRUMENTS I.T.I.S. A. Volta-Napoli DIMENSIONING OF CIRCUIT COMPONENTS : COMPONENTS HAVE BEEN CHOSEN IN ORDER TO OBTAIN A RESONANCE FREQUENCY OF APPROXIMATELY 870 Hz AND TO LIMIT THE CIRCUIT CURRENT TO A VALUE NOT EXCEEDING 5 mA

  23. TEST RUN ISTITUTO TECNICO INDUSTRIALE STATALE “ALESSANDRO VOLTA” NAPOLI DG Education and Culture Leonardo da Vinci PARTNERSHIPS

  24. TEST RUN I.T.I.S. A. Volta-Napoli THE CIRCUIT WILL POWERED BY A SINUSOIDAL SIGNAL VARIABLE FREQUENCY FROM 10 TO 15000 Hz N. 25 MEASURES WILL BE MADE FOR VALUES OF GROWING FREQUENCY. BY INCREASING THE FREQUENCY THE CURRENTE VALUE WILL INCREASE ACHIEVING ITS MAXIMUM VALUE AT THE RESONANCE RATE. AFTER REACHING ITS RESONANCE RATE ITS VALUE WILL DECREASE.

  25. TEST RUN I.T.I.S. A. Volta-Napoli

  26. THEORETICAL FORMULA ISTITUTO TECNICO INDUSTRIALE STATALE “ALESSANDRO VOLTA” NAPOLI DG Education and Culture Leonardo da Vinci PARTNERSHIPS

  27. THEORETICAL FORMULA I.T.I.S. A. Volta-Napoli V = Z I Z = R + j (XL – XC) XL = 2*π*f*L XC = 1/(2*π*C ) fr = 1/(2π*L*C )1/2 I = V/Z
