How do I calculate street light voltage drop?

Hi Sam, 1) 3Ø - 480: Vd-Value * sqrt(3) 480 2) 1Ø - 277 Vd-Value 277 3) What about 1Ø - 480? Is this formula below correct for 1Ø - 480? To calculate for Vd-value, do we use 1Ø formula? Vd Percent= Vd-Value X100 480

To find the voltage drop percentage for 1 phase and 3 phase, do we divide both by 480V?

Thank You!

Can someone please tell me where can I find a lot of C/T and P/T practice questions?

If we do not use 4 hours in the morning exam. Can we use it for afternoon exam?

Question 540) Question asked for contributions of G1 . But why does the solution include both G1 and T1?

Question 531) Can someone help me with this question? In the solution it is divided by a square root of 3. Why do we divide by a square root of 3 and later it is multiplied by 3. If it is 3 phase how do we know it?

Thanks.

What is pretest items?

A test of a 10 KVA, 2300/230V, single phase transformer gives an open-circuit test power consumption of 69W, and a short circuit test reveals a resistance referred to the high voltage side of 10.9 ohm. The efficiency of this transformer, operated at full load and unity power factor is most...

0.035+0.049j *(500/1000*2) Why is it divided by 2 in the solution?

You can go to any Pearson VUE test center. I does not matter in state or out of state.

WOW! CBT is expensive $375 + tax.
