A Phase monitor was not pulling in today on a piece of equipment so I was checking the voltage. There is a transformer that knocks the Voltage down from 480 to 240 Delta Delta Config. I have attached an image of the winding setup for the transformer to this post. The 480 is wired and tests as follows.
Prim
H1 with 1 285 to Gnd
H2 with 2 265 to Gnd
H3 with 3 262 to Gnd
Sec
X1 115 to Gnd
X2 119 to Gnd
X3 191 to Gnd
X6 is not connected.
I spoke with Sola HD on the phone and they told me I need to have X6 to Gnd I told them I need 240 Phoundase to Phase and If I connect X6 that will give me 120. Speaking to another person they told me I need to have any one of the phases grounded or it will not test right.
I cant up load the pic so its on page 9 of 10 electrical connection 28
