Combined Load Banks
Both resistive and inductive load are required for testing AC supplies at non unity power factors. Since most generating sets are rated at 0.8 power factor (or CosØ), testing at rated conditions is conveniently done with a combined load bank.
Various configurations are possible and larger load banks, typically above 1200kVA, are based on an ISO container construction.
Standard or custom-built load banks can be supplied for most voltages, frequencies and sizes. Multi-voltage load banks are also available for operation over a large voltage range.
Load banks are available in static versions for permanent installation or movable format with fork lift pocket base, castors or full road going trailers. Larger load banks, typically above 1200kVA, are based on an ISO container construction. Special finishes including custom paint colours and stainless steel casings can be supplied.
