Most utility companies will not hook up 3 phase delta on the customer side anymore because the the high or wild leg which as shown in the diagram runs a good deal higher than 120 volts to neutral.
Open deltum wiring diagram. V p phase voltage v l line voltage i p phase current i l line current r r1 r2 r3 resistance of each branch w wattage w delta 3 w wye w odelta w delta w owye w wye. V a 3 v l i p h. The above figure shows the connection diagram of an open delta system. Each transformer is rated as 10 kva current rating is 10 a and voltage rating is 1000 v.
At best this looks like 120 240v 3 phase 4 wire service and it looks to me like the voltage from a phase to neutral. Regular 3 phase delta looks like this. In this diagram a three phase unity pf load resistive load is supplied by two transformers. This means an open delta transformer will only be able to deliver 57 7 of the capacity of an equivalent three phase delta transformer with similar voltage and load current.
3 v l i p h 3 v l i p h 0 577 or 57 7 summary. The only response i got from the engineer from my rfi was the buck boost transformers are wired open delta. This is the same as multiplying the complex value by negative one to change the direction. This is the closest wiring diagram i can find and the engineer has given no more information than i have already typed.
3 phase delta power. 3 phase open delta power. Alternate way of stating the same is that if a delta delta transformer is converted to open delta transformer then the new transformer will only be able to supply 57 7 of. Looking at the open delta diagram the b phase current is equal to the negative b line current since they are flowing in opposite directions.
Everything seems to be correct when the vab voltage numbers are compared to the ia currents but the relay is actually measuring a leading current. Open delta transformers are three phase devices with only two windings on each of the primary and secondary sides. It can be observed that at point a kirchoff s current law kcl is satisfied. This video explains the correct and proper wiring of open delta open delta transformer banks.
