To be clear. I am removing a reduced voltage starter from a stand alone cabinet. It has 480V on the line side and 120 in the control. The 120V comes off a transf which has the 480V as I just mentioned. This type of reduced voltage starter has an "auto transformer configuration on the line side"...
Hello:
I am currently trying to write the "working instructions" to remove a reduced voltage starter circuit hooked up to a 100hp motor that activates a fan. The reduced voltage starter has a auto-transformer configuration. Wanted to know if there are any electricians/engineers that know, OR...
The problem is I keep hearing different ideas as to why a soft starter is compatible OR not compatible. One tech support specialist says because their(soft starter) rated insulation voltage-to-gnd is 600VAC. Another person says if a soft starter use MOVS on the front end to protect SCR's ARE NOT...
I have a dilemma. Basically, Im implementing a soft starter to replace a old reduced voltage starter circuit. I found several potential good soft starters. However the problem was I overlooked the fact that the power system that the soft starters will be connected to is corner grounded delta...
