TYPICAL NO-LOAD LOSS AND LOAD LOSS FOR POWER TRANSFORMERS

Typical No-Load loss and Load loss for Power Transformers according to MVA capacity.

No-load loss and Load loss in Power Transformers varies significantly depending on different factors. Here you can find the typical value for the no-load loss and load loss according to power transformers having Load Tap changers and those having none. Different MVA capacity means also having different values for the power transformers' no-load and load loss.

Typical No-Load and Load Loss for Substation Power Transformer Units Without Load Tap Changers.

No-Load loss and Load Loss

*Annual kWh losses are based on transformer loading at nameplates, loss factor of 0.3 and auxiliary loss factor of 0.1.

Typical No-Load and Load Loss for Substation Power Transformer Units With Load Tap Changers.

No load loss and load loss with LTC

*Winding losses are based on maximum raise or lower LTC tap position setting.
**Annual kWh losses are based on transformer loading at nameplates, loss factor of 0.3 and auxiliary loss factor of 0.1.

    Hello,

    i am representing www.mrosupply.com - industrial goods ecommerce store, extension of a family owned 114 year old business selling motors, electrical components, conveyor belting and related products. In this, we are looking for opportunities to buy inexpensive links from various blogs, websites, etc.. We would like to get a small tiny link on your website, on the homepage preferably. How much would that cost?

    Thank you in advance.
    Regards,
    Yanina Dani

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").
