ETAP Single Phase Load

12/22/2011 1:31 AM

Hi, I am carrying out a distribution system analysis on ETAP. While trying to connect a single phase load, ETAP recognizes the load as single phase but the current drawn in overhead lines is distributed on all phases. Example, I connect a single load on Phase A which draws 30 Amps, but the transmission line before this load shows a current of 10 amps on each phase. I tried using Phase adapter but I couldn't get it to work. Is phase adapter the way out or should I use something else? Regards, Usman Hassan

Use unbalanced load flow analysis

Yes..or maybe..

a) you can still use balanced load analysis, but when you are using a phase adapter you need to have a cable connected on the single phase side. and when you make your load flow analysis, please take note to check the "update cable load amp" so that you can monitor the load that passes through the cable. it will indicate single phase load.

b) the correct way would be using unbalanced analysis, but still to need to use the phase adapter and dont forget to use the cable to connect the single phase load to the phase adapter. and then simulate the unbalanced load flow.

always make sure that you enabled the per phase display after the simulate so that you can see or check the results.

thanks!! God bless..
