Description
A medium-power plant can be built without a 6–10 kV generator voltage, delivering power through a unit step-up transformer. Shaft height is 355–710 and the pole count 4–20, that is 1500–300 rpm at 50 Hz, so the shaft couples directly to hydro turbines of different specific speed. Class F insulation. Protection is IP23 with open self-ventilation IC 01 or IP55 with a closed circuit and air–air heat exchanger IC 611. Mounting IM B3 or IM V1 covers horizontal units with Francis and Pelton turbines and vertical ones with axial turbines. The word "compact" in the name means reduced size and weight, but the site gives no weight and dimension figures.
How to choose
If the plant is smaller, the 100–2000 kVA range is covered by the 0.4/0.69 kV synchronous generator, and the 100–2000 kW induction generator is chosen when voltage regulation and stand-alone operation are not needed. The compact design wins where the building is small or a generator is replaced on an existing foundation. Data on efficiency, short-circuit current and excitation parameters for a frame size are requested from the manufacturer using a questionnaire.

FAQ
What is the maximum power of the compact low-voltage generator?
Up to 5000 kW at 400–690 V and a frequency of 50 or 60 Hz.
Is a 6–10 kV generator needed for a powerful small hydropower plant?
No. With a low-voltage machine up to 5 MW, power is delivered through a unit step-up transformer, without a 6–10 kV generator voltage.
What speeds and number of poles?
From 4 to 20 poles, that is 1500–300 rpm at 50 Hz. Shaft height 355–710.
What protection degrees and cooling are available?
IP23 with open self-ventilation IC 01 or IP55 with air–air heat exchanger IC 611.
