for AC parameters
• Socket for connection to the spotlight AC 220V

Sci-Cal^R PC data acquisition

• The trainer includes a data acquisition board with USB interface for connection to PC and voltage and current converters.
• • A specific software (developed with LabView) is supplied to monitor the system parameters.

   

• Parameters displayed:
  – All DC and AC parameters

  – Water pressure and flow rate

  The software enables to:

  – Calculate the hydraulic energy conversion efficiency

  • –  Visualize the energy flows to and from turbine-generator

  unit, battery pack (if present) and inverter

  • –  Draw the characteristic curve efficiency / flow rate to find

  out the point of maximum performance of the turbine- generator unit

  Experiments

  • Components of a stand-alone hydraulic system for electricity production
  • Effect of water pressure variation on the electric power produced by the generator
  • Effect of applied load variation on the electric power produced by the generator
  • Hydraulic energy conversion efficiency
  • Battery charging system management
  • Operation and efficiency of a DC/AC inverter
