ETAP SOFTWARE REAL-TIME MONITORING WITH SCADA INTERFACE VIDEO TUTORIAL Video tutorial on how ETAP software is used for real-time monitoring In this video you will see how ETAP software is used for real-time monitoring of the system. Watch the video to understand more.

LOADING POWER TRANSFORMERS BEYOND NAMEPLATE RATING:SIMULATION SOFTWARE VIDEO Power transsformers are one of the most critical asset in any power system network. Transformers undergoe different load cycles that vary depending the time of day and year in power system conditions. For example, the daily load cycle tends to increase during the early hours of the morning before people leave for work and in the evning after they arrive home. Similarly, a yearly load cycle during the hot summer months when high ambient temperature cause consumers to ramp up their air conditioners and use more electrical power. During contingecy conditions, single or variuos network elemaents such as transsmission lines, generators or transformers might be isolated from the power system. As a consequence,transformers can become overloaded by reaching magnitudes above its maximum nameplate capability affecting and possible reducing the overall life of the transformer.During transformer overloads, theextra pow

CONSTRUCTING POWER TRANSFORMERS: VIDEO Construction of power transformers undergoes a rigorous process. A video presentation of ABB shows the step-by-step process in manufacturing this complex electrical power apparatus. Shown also in this video is the part-by-part construction, from winding, core, tank, accesories up to the delivery of the power transformer is clearly explained in this video. ABB is a major transformer manufacturer throughout the world. ABB power transformers are built and designed to meet the individual customer's needs. This experienced attendance to details lies behind the success of ABB's transformers. This approach is carried throughout the manufacturing process: design, core, winding, drying, tank, quality assurance, assembly, testing, transport and installation and support.

ETAP LESSON 8:INSERT PROTECTIVE DEVICE WITH ETAP SOFTWARE Learn how to add protective devices like circuit breakers, switches, fuses, etc. to an existing one-line without breaking any equipment connections.

ETAP LESSON 7:WORKING WITH COMPOSITE NETWORKS Learn how to use and manage composite networks and organize your existing one-line diagrams for better presentation and printing.

HISTORY-EARLY TRANSFORMERS 1895-1920  A tour of the three generations of transformers that helped make possible early power transmission. These step up transformers sent power 22 miles to Sacramento with a 10% loss. The first transformers at Folsom(1895) were air cooled and made by William Stanley - pioneer of the transformer. The second generation was made by Westinghouse, and the third by Alice Calmers (1920).

Here in lesson 5, we will further understand the load flow module of ETAP. Load flow analysis is very helpful not only in determining the voltage and power flow but most especially through this we will be able to compute for line loss in transmission lines. ETAP is very effective in simulating the transmission and sub-transmission lines but it has a slight disadvantage if you would like to run a distribution line analysis.
