Multibus II system using iRMX III and Dos 6.2
There are many generic ANSI C statements (eg) printf("Process Init \n);
The printf is not directed to stdout under iRMX
The printf statements do not show up on any screen, does not show up redirected to a com port , lpt port , etc.

Say you have 4000amp feeder breaker feeding 4 conduit sets of three 500mcm cables at 34.5KV on a 800 ft run (lets assume pvc buried 6 ft in the ground). So, we have 4 conduit runs with three 500mcm cables per conduit.
My question is what size grounding cable does the NEC require to run in each...
I understand that the primary (conductor) passing through the window CT creates a magnetic field that induces voltage/current in the secondary of the CT. This makes me think a window CT will work on a shielded cable because the shield is designed to create a unified electric field. My question...
I am looking for a wire wound resistor for an RC network with the following specs:
50 ohms, 60 or 70 thousand Joules, and 75kV withstand
Does anyone know of a company that I could get this from?
Be Safe.
NEC article 110.34 and Table 110.34A I see that you are required to have a 6ft clear distance from 25KV - 75KV. Does this apply to enclosures such as 34.5KV disconnect vaults on a primary sub?

Is there any NEC regulation on putting an awning over a 34.5KV - 4160V outdoor transformer and switchgear? Required height, material, etc..?
NOTE: awning is to prevent large amounts of rain building up on transformer pad
Be Safe.
I have 34.5KV line to 4160V. On the primary side of the transformer there is a vault with a disconnect switch (3 phase). This is fed from an overcurrent protection device some distance away. There has been problems with the disconnect switch so Im looking into getting rid of it, and I was...
