SpletHowever, the fault current generated by an induction motor will only last for a few cycles. The current will be approximately equal to the locked-rotor starting current of the motor. Electric utility system: most of the fault current typically comes from the electric utility. The level of the short circuit current will depend on: SpletA busbar has a much higher maximum current rating, normally a 1600 A riser can withstand 60 – 70 kA. Installation time Busbar installation wastes less time. Busbar Size vs Current. Observe the short circuit rating for a busbar below: Current rating 0 – 400 A = 25 kA for 1 second. Current rating 600 – 1000 A = 50 kA for 1 second. dog breeds by colorSpletLED是「Light Emitting Diode」的縮寫，中文名稱為「發光二極體」。 LED是一種特殊的二極體，加正向電壓時，發光二極體能發出單色、不連續的光，這是電致發光效應的一種。在散熱技術與材料發光效率提升之後，未來在照明用途上將逐漸取代傳統的白熾燈泡。 facts for sharks
