You could try SAJ Private Ltd.,Manufacturers of Dynamometers (Hydro & Eddy), PUNE, Maharashtra, INDIA

It's been some years since I was in touch with them; I do not have the exact postal address. I will look up google and advise you do the same please. I do know that they make good quality systems as per my experience.

Hope this is helpful.

Further to my recent reply to you, here's what I found on Google search:

SAJ Dynamometers Pvt. Ltd.

12, Kaka Halwai Indl. Est.,
Pune Satara Rd.
Pune - 411009, Maharashtra

Contact Person : Mr. D M Jagtap

Thanks for that Mr. Naidu.

Since you quote the engines in kVA i suppose you are dealing with small generators. Why do you not just build a simple resistive load bank from cheap room heaters (1kW) and halogen flood lamps (typically 300 or 500W)? Alternatively use water heater elements.
