Soft Starter Controlling Current To Transformer
#1

I am building a 3 phase converter using a 15 kva transformer to generate the 3rd leg. I need some way to bring my transformer up with out a huge inrush of current blowing fuses. Can I use a soft-starter for this or are they designed exclusively for motor control.
Thanks

Yes, you certainly can use a soft starter to control a transformer, cone it plenty of times, but it may depend on your circuit configuration and on the transformer configuration.
If you use a three phase soft starter, it will probably expect the output to be balanced and three wire only. If you use a single phase soft starter and transformer, ensure that it is rated for the voltage.

Thanks for the reply . I had ordered a couple and was hoping I had not wasted my money. It is a single phase configuration (230 volt ) US operation and I ordered 208-240 volt devices.
Also since I have never worked with these devices, do they vary the voltage to the controlled device or vary/limit the current to the device.
Are the manually adjustable ?
Thanks
