Hi Larry, is the answer on this one 150Kvar assuming 3 150Kvar are in series and the 3 x 3 150Kvar are in parallel to form a delta bank?

150 X 9 = 1350 KVAR it does not matter if they are delta or wye connected. This question is in the electrical PE exam.

I took the NETA 4 today. there are absolutely zero questions from this NETA 4 study guide that are on the actual test (at least the version i took). there are variations of the 4 just as there are of 2 and 3. I only had about 3 level 3 questions on the test. the remaining questions were challenging.

Several distance relaying questions, several KWH standard questions, a few breaker tripping scenario questions, and a lot of power calculations. I also ran into several rotating machinery questions. A lot of these were very difficult for me as i am not well versed on the construction of older motors.

Study all aspects of the topics listed above if you are scheduled to take this test.
