precisely what is usage for ability Consider industries?? two.why we need to observe power component?? 4 Solutions Havells, how to work out the kw, Amps eaten by a capacitor, give me the formulation for KVAr into capacitance,KVAr into KW & KVA, Amps three Answers Why we've been receiving low voltage in star link? two Answers if its attainable for step up or stage down DC volage directly ? possible means how we will get it done ? five Solutions
Thus the magnetic flux expected for the production of a specific secondary recent is lessened to one-third (1/three), which can go here be the most significant advantage as the overall sensitivity in the defense process is amplified.
零相変流器の２次側に保護継電器を設置しておき、電流が流れたら遮断器を開放するようにしておけば地絡事故発生した場合に迅速に故障箇所を電気回路から切り離すことができます。これが零相変流器の設置目的と使用法です。
電流には必ず行きと帰りがあり、通常その電流の大きさは同じになります。しかし地絡が発生すると、電流が正常な回路を通らずに大地を通って帰っていきます。これを漏電とも表します。
The way in which ground fault is detected is through 50G (Pickup=2A, TD=close to 2sec) and in addition through the 59G and 67G, even so the designer explains the 59G/67G, is just for backup safety. The main security should really even now be 50G, which somehow produced numerous GF when phase B was faulted (as shown in the relay log), for which the sytsme was registering mutilple floor faults "mysteriously" elsewhere downstream with the tie breaker (diagram). But before I digressing into distinct matters, I would like to point out based upon the technique I have described thus far, are we utilizing the appropriate CT for this applications? Many thanks.

secondly makers occasionally have added requirements; by way of example Siemens’ overcurrent, motor security, line differential (non-pilot)and transformer differential are good to go along with the above mentioned, when their line differential (pilot wire) and distance relays have to have the above mentioned and possess further constraints on K’scc
変流器は、高圧や特別高圧の回路で大電流が主回路に流れる時、その電流を扱いやすい大きさに変換する機械です。この変流器は多くの箇所で様々な用途で使われています。目的によって選定する機器は変わりますし、使い方によって結線が変わります。ここでは、そ...

三相交流電源では、それぞれに流れる電流が等しく対称である場合、そのベクトルの和はゼロです。
