Simulating Open Delta Connection
Simulating Open Delta Connection
(OP)
This is my first post here.
I am working on some project, where the customer PT (sec.) is connected in open Delta. We need to test our system and need to mimic the open delta connection. I am using Omicron to simulate the voltage coming from the PT and can't simulate the open delta (with grounded B phase). The PT is going to UGE modules (Generator voltage modules).
Any ideas how I can do this. What do I need to put between the Omicron and my UGE modules?
Thank you

Thanks. The light bulb lighted after I made the post :)

1. Use A,B,N set A phase of the Omicron to 30 degrees and connect to A of the PT connection, Set B phase of the Omicron to 90 degrees and connect to C of the PT connection. Connect N to B phase. This will simulate the delta connection and if your current will be correct for power when A is set to an angle of 0.
2. Use A,B,C at 120 degrees apart. The only trick to this is that the grounded B phase will be be at negative voltage which may or may not work well depending on what else is connected.
