Acoustic system for scaring away from fish from e.g. cooling water inlet for power station, comprises spark and high voltage pulse generators

摘要

The acoustic source comprises at least one spark generator (5a-5e) for producing acoustic pulses. The control unit comprises one pulse generator (7a-7e) per spark generator, used for generating high voltage pulses. The acoustic source is located underwater, close to the water inlet (2). The control unit for this source is located above water.
