A list of top frequently asked Electrical Machines interview questions and answers are given below. A Single-phase autotransformer is a single winding transformer in which a part of the winding is common to both high-voltage and low-voltage sides. This law states that when we move any current carrying conductor in a magnetic field, then an EMF is induced in it.
Avoid These Three Phase Power Formula Mistakes!
I want to share with you the the most common mistakes that students make with three phase power formulas that lead them to getting robbed of correct answers on the PE exam, and remind you why specific notation is so important. So you write down the formula, punch in a few numbers in your calculator, and circle the right answer. There are a few specific topics on the electrical power PE exam that this is most likely to happen, and one of them is three phase power. Most of us, are very familiar with using and writing down the following three phase power formula like this, without taking care to use proper notation:. The correct way to write the three phase apparent power formula that uses the square root of three is not like this incorrect :. Instead, get used to writing it down with the proper notation that will save you in the future correct :. I know what you are thinking.
NCEES, the entity in charge of handling licensure for engineers in the US, has recently announced that it is updating the FE exam specifications, changing each exam's categories and the reference handbook for FE Exam test takers starting July In other words, the questions seen by July and after test takers will be different than the questions seen by June 30, and prior test takers. Because these changes were just announced, you will find that a lot of the textbook FE prep material includes topics that might not be in the new exams as some of the textbooks are now outdated. You will be using this pdf during the actual FE exam. While specific topics may have been removed from listing in the most recent FE Exam Specifications, they may still be topics that are covered in other, broader categories. Be sure to keep this mind while reviewing these changes from July, To those of you using PrepFE to prepare for your FE exam: we've updated our site and iOS apps so that you may prepare for the appropriate version of the exam you are taking.

A V-V connected transformer can be connected in parallel to delta-delta connected transformer but not to. The V-V connected transformer and D-D connected transformers have same phase displacement, so they only can be connected in parallel to each other. Three single phase transformers and one single unit of three phase transformer will be same only. Delta connected winding handle line voltages so it needs more turns in the winding but thin wires. If para magnetic core is used in the place of the ferromagnetic core of the transformer, then magnetostriction will.

Фонтейн смотрел в окно, пытаясь понять, что происходит. За несколько лет работы ТРАНСТЕКСТА ничего подобного не случалось. Перегрелся, подумал. Интересно, почему Стратмор его до сих пор не отключил. Ему понадобилось всего несколько мгновений, чтобы принять решение.
Чуть ли не до двадцати лет она была худой и нескладной и носила скобки на зубах, так что тетя Клара однажды сказала, что Господь Бог наградил ее умом в утешение за невзрачные внешние данные. Господь явно поторопился с утешением, подумал Беккер. Сьюзан также сообщила, что интерес к криптографии появился у нее еще в школе, в старших классах. Президент компьютерного клуба, верзила из восьмого класса Фрэнк Гут-манн, написал ей любовные стихи и зашифровал их, подставив вместо букв цифры. Сьюзан упрашивала его сказать, о чем в них говорилось, но он, кокетничая, отказывался.
