Combined load banks

Combined load banks provide both resistive and inductive (lagging) or resistive capacitive (leading) load and are used for testing AC supplies at non unity power factors. Most generating sets are rated at 0.8 power (or Cos Ø) and testing at rated conditions is conveniently done with a combined load bank. Heavy duty welded monocoque or modular chassis construction capacities are available up to 2000kVA (for larger capacities see our containerised load banks).

Combined load banks can be customised for a particular application. Stainless steel, non-finned, sheathed elements and iron cored inductors are used that allow both three and single phase operation. Continuously rated for both 50 and 60Hz operation at the maximum voltages specified. Combined load bank inductors are specifed to cope with typical harmonic distortion found in gen-set and renewable energy sources.
