BACK TO BASIC


In case you don't know, the power we get from our household electrical outlet didn't just appear in the thin air. It may appear that it is coming out from our walls but we all know that looks can be deceiving. Before reaching our respective homes, electric current passes through miles and miles of conductors. Whether you have an electrical background or not,one should be aware that any load like television, radio, computers, and other devices which utilizes electricity must have a source.The source that I am referring is the one which supplies not only our own home, but also the whole community.AC generators and batteries are some of the good examples of an electrical source.To know more about the basics of the basic of Electrical Power,you can refer to this site.

To understand more of the flow of electrical power with respect to source-load relationship,you may refer to the illustration below.



All the action begins at a generating plant, electrity is generated from one form of energy like from water energy,wind, solar, nuclear. After electrical power is produced, it is then converted to a higher voltage level for transmission purposes. Through the use of conductors(i.e transmission lines), power is transmitted for it to reach substations where it is then converted back to a voltage level where it can be utilized. Transformers found in the substation converts voltage to a level that can be distributed while distribution transformers are use to convert it to a level which a common household can enjoy.

PARTS OF A POWER TRANSFORMER

What are the name of the basic parts of a Power Transformer? We can not deny the fact that only a handful of electrical engineering students are presently familiar with power transformers especially on what it looks like. Unlike a transformer we found in our homes, a power transformer’s appearance and construction is somewhat more complicated. It is not just a simple winding with a primary and secondary terminal although basically any transformer has one. The function that a power transformer plays in an electrical system is very important that an electric utility can not afford to loss it during its operation. Our discussion here will focus more on the basic parts and functions of a power transformer that are usually tangible whenever you go to a substation . Although not all power transformers are identical, nonetheless they all have the following listed parts in which the way of construction may differ.

ELECTRIC MOTOR FRAME SIZE STANDARD SPECIFICATIONS

ELECTRIC MOTOR FRAME SIZE STANDARD SPECIFICATIONS How is electric motor frame size being specified? Motor frame dimensions have been standardized with a uniform frame size numbering system. This system was developed by NEMA and specific frame sizes have been assigned to standard motor ratings based on enclosure, horsepower and speed. The current standardized frames for integral horsepower induction motors ranges from 143T to 445T. These standards cover most motors in the range of one through two hundred horsepower. Typical example of where you can locate the frame is shown in Fig 1.2.D – Frame No. The numbers used to designate frame sizes have specific meanings based on the physical size of the motor. Some digits are related to the motor shaft height and the remaining digit or digits relate to the length of the motor. The rerate, or frame size reduction programs were brought about by advancements in motor technology relating mainly to higher temperature ratings of insulating mate...

ELECTRIC MOTOR NAMEPLATE SPECIFICATIONS

How do we interpret an electric motor nameplate? Motor standards are established on a country by country basis.Fortunately though, the standards can be grouped into two major categories: NEMA and IEC (and its derivatives). In North America, the National Electric Manufacturers Association (NEMA) sets motor standards, including what should go on the nameplate (NEMA Standard MG 1-10.40 "Nameplate Marking for Medium Single-Phase and Polyphase Induction Motors").
