Hello everyone, I am faced with a problem where I have to power a 30kw drilling pump, with a generator of 45kw (model Gesan), but it does not work. At start-up the current reaches the peak of 190 A and descends gradually, for information the start-up of the pump of the drilling is done by a starter Altistart 22 of Schneider with an acceleration set to 15 seconds, and the generator sets overcurrent fault and stop. I heard that for this kind of application the generator must have a power of at least 3 times the pump. At the moment I am doing tests by acting on the parameters of the starter: acceleration and limitation of current. Thanks in advance for any help.
