  • Budget Protection Relay Tester

    Thanks a lot for the feedback. I have been looking at Kingsine for some time, but I was always very tentative given the reputation of some of the Chinese brands. Ponovo is another Chinese brand on my radar, but I have received some positive recommendations for Kingsine. A senior field Engineer with a lot of Omicron equipment actually recommended the Kingsine...

  • Budget Protection Relay Tester

    We purchased a Kingsine KFA310 for the same reason. It has been about 6 months and so far we haven't had any issues with it. It does everything that we need, but we aren't doing heavy duty relay testing every day. The 310 has 3 currents and 4 voltages, and we paid to have the currents upgraded to 30A output capacity (50A single output). I think all in it...

  • Measuring Capacitance Across A-B Terminals

    For clarity on this, the answer is 576 due to capacitors in series reciprocate. Since the terminals on A and B are measured and in series, the capacitance of 1152 reciprocates or simply its just half. Same as when two 100 ohm resistors in parallel half to 50 total Resistance. Seems like everyones math is on point, just one of those small details that NETA ...

  • Most suitable power-factor test voltage for 13.8kV?

    I just performed this test on this exact scenario. Kalbi Rob is 100% correct. I spoke with Doble about this as well and they confirmed the same. What i would like to know is, how critical are the actual test answers. Kalbi's answer is true however the question said power factor specifically. Would they not accept the 2k and 8k answer because it doesnt state...

  • Budget Protection Relay Tester

    Good day, Can anyone recommend a good reliable budget brand for Protection relay testers? There is no need to have advanced features, just the equivalent of QuickCMC from Omicron and enough rated burden to test digital and most typical EM relays.

    **Convert the vector (–1.0, 1.0) into magnitude/angle form.** Answers have -45, 0, 2, 45, and 135 degrees as potentials. -1,1 is in the third quadrant, meaning the angles should be between 180 and 270 degrees (in this case 215), vice the I believe 135 degree which is marked as the correct answer.
