  • Michael Bay's Transformers: Age Of Extinction

    President of MPPA Jack Valenti and he was correct in saying so. The fourth installment of the Transformers: Age of Extinction, may have missed the mark at U.S. box offices, but there are many countries around the world where the film profits did not disappoint specifically China. The international success found in China from this film can be closely attributed to the nostalgia this movie carries, the strategic marketing done by the producers through the trailers specifically, and the universal…

  • Tesla Coil Essay

    In essence, Tesla coils are a high-voltage, resonant transformer circuits. They consist of the six major components (Behrend 1), namely: Primary transformer Tank capacitor Spark gap Primary coil Secondary coil Toroid Figure 1: Tesla coil (diagram) A primary transformer is a step-up transformer that takes the line voltage of the AC source and steps it up to a range between 12 kV and 50 kV at 60 Hz (Johnson 4). The efficiency of this transformer is largely dependable on the construction…

  • Schematic Diagram Of Power Line Guardians Case Study

    If F-PLCCG status is “OK” it will execute as in Step 3, if it’s “NOK”, it will execute as in Step 5. Step 3: Stop “X” Signal from Transformer PLC. F-.PLCCG Receives Communication signal “Y” from Street 1 of PLC Modem and Status of Transmission line send to Sub-Station “A” & Control Box at T/F (Transformer) via Communication system arranged in “F-PLCCG” and F-PLCCG sends only “OK” or “NOK” Signal to Sub stations. If F-PLCCG status is “OK” it will execute as in Step 4, if it’s “NOK”, it will…

  • Single Phase Single Stage Boost Inverter Study

    Whereas third scheme, involves first step up operation and then inversion. To increase the output ac voltage from a dc source, usage of a conventional voltage-source inverter (VSI) fed step up transformer can provide simple solution. In [2], a step-up transformer is utilized at line frequency to boost the voltage coming from inverter. However, this solution is suffering from several disadvantages, such as loud noise, high cost, high volume, bulk size, lesser power/weight ratio and relatively…

  • Analyse The Value Of Voltages In Generation, Transmission And Distribution?

    Where it is then stepped down at the substation to 132kV, A step down transformer is a piece of electrical machinery, which takes high voltages as they come through the input and make them lower as it passes through the output. For this conversion process to take place, the transformer needs an altering current voltage; this is as the coil relies on a magnetic field to generate a voltage. Step down transformers have a primary and a secondary coil, which are tightly wound together so that there…

  • Rebar Essay

    System is based on Arduino mega board. Arduino is microcontroller, which will run the predefined program to process input/output on its GPIO pins. Better than Raspberry Pi, Arduino has some GPIO pins that could accept analog input, and has several (usually 6) GPIO pins .That is used to convert analog i/p to digital O/P. The communication between the microcontroller and the SD card module uses SPI, which takes place on digital pins 50, 51, and 52. Fig. 1. Block Diagram of system Input to…

  • BES Reliability Operating Services

    The services are considered essential to the operation of the BES asset, so any Cyber Asset associated with those services would be considered essential, and should be evaluated to see if qualifies as a BCA. Below are two (2) examples on how the BROS can be applied to a Cyber Asset to determine if it is essential to the operation of the BES asset. Example 1: i. At a generation BES asset, there are protection relays installed at the step-up transformer (GSU) to protect the actual generation…

  • AC Voltage Advantages And Disadvantages

    AC stands for alternating current which means that the current flows in both directions. So instead of flowing from one source to another, the current can flow from both the source and the recipient to each other. AC voltage is the current that comes from an electrical plug. An advantage of AC voltage is the fact that the power of the voltage can be altered with a transformer. Fig.1 graph showing AC and DC current On the other hand DC voltage stands for direct current. This means that the…

  • Wind Distortions Essay

    Harmonics: Harmonic distortions are injected at the generation as well as the consumer end. At the consumer end, harmonics are caused by nonlinear loads such as PCs, CFLs, electronic devices, etc. The harmonics distortion caused by non-linear load such as electric arc furnaces, large concentrations of arc discharge lamps, variable speed motors, saturation of magnetization of transformer and a distorted line current. The current generated by such loads will interact with power system impedance…
