Selection issues for autotransformer starting devices
Thread Content
Our company has two 37KW 380V self-priming pumps, and we intend to use the autotransformer step-down starting method; the initially selected model for the autotransformer is JJ1B-37/380-2 (wall-mounted type). I would like to ask fellow sea users whether the autotransformer models they have chosen are capable of powering a 37KW pump! ! Thank you all first! ! ! 1
It is usually advisable to choose a larger model, as this makes it less likely for the windings to burn out during continuous testing and startup.
