Engineers provided by the generator company have a similar solution, but with some type of voltage regulator/stabilizer. I will get this whole forum discussion to them before they implement anything. I expect Bentov's solution is far cheaper.
As for the switching, there is no separate bypass...
The 3RW44 is the model 3RW4447-6BC34. A manual on this has this as 385 A rated operating current, 150 HP @ 230 v and 300 HP @ 460 v. This is borderline satisfactory for a 230 kw motor? I am waiting for the generator agent to give me the AVR specifications.
Thanks so for for this help. I have...
Hi Bentov, thankyou for your reply - you have identified exactly the "overshoot" moment that has been noted by the Siemens technicians. We will likely work with the generator supplier to try and implement your two solutions. The manual has 110% ("Control supply voltage is above 110 % of the...
We have a Siemens Sirius Soft Starter 3RW44 supplied as part of a pump system. The 3RW44 soft start is connected to a Siemens 230 kw motor (, 60 Hz, 380 volt, 415A on the plate). The motor is mounted and connected to a floating pump (chain drive).
We have a 750 KVA Doosen generator connected...
