How can I test the load output of my hydro turbine without breaking the bank?

SUMMARY

The discussion focuses on cost-effective methods to test the load output of a hydro turbine expected to produce between 4 kW and 7 kW. A participant suggests using an old generator with a defective engine, such as the Robin RGD 5000 Watt Diesel Generator, to obtain the necessary load output data without incurring high costs. Another participant considers using a heavy truck 24V alternator, but questions its capacity to handle approximately 200 amps. The consensus emphasizes utilizing existing equipment to minimize expenses while achieving accurate testing.

PREREQUISITES
  • Understanding of hydro turbine mechanics and output expectations
  • Familiarity with electrical load testing methods
  • Basic knowledge of generator specifications and capacities
  • Experience with alternator functionality and calculations
NEXT STEPS
  • Research how to calculate load output using a heavy truck 24V alternator
  • Explore options for purchasing or acquiring defective generators for testing
  • Learn about the specifications and performance of the Robin RGD 5000 Watt Diesel Generator
  • Investigate alternative methods for load testing hydro turbines on a budget
USEFUL FOR

This discussion is beneficial for DIY renewable energy enthusiasts, hydro turbine builders, and individuals seeking affordable methods to test electrical output in small-scale energy projects.

Hi Everyone, I am building a hydro turbine, I am expecting it to produce circa 4 kw possibly as high as 7 kw depending on flow. I am on a very limited budget. Please could you suggest possible means of getting load output data? I have considered attaching a heavy truck 24 v alternator and doing a simple calculation from amp output but I'm not sure I can get a big enough alternator, around 200 amp?
Thanks
Nick

Find yourself an old generator of the proper power output, ideally with a defective engine to keep the cost down. For example, something similar to this http://www.ebay.com/itm/Robin-Rgd-5000-Watt-Diesel-Generator-For-Parts-/111523201105?pt=BI_Generators&hash=item19f74d0051.
