Introduction to energy generation

Prior to the discovery of Faraday’s Laws of electromagnetic discussion, electrical power was available from batteries with limited voltage and current levels. Although complicated in construction, D.C. generators were developed first to generate power in bulk.

However, due to limitation of the D.C. machine to generate voltage beyond few hundred volts, it was not economical to transmit large amount of power over a long distance. For a given amount of power, the current magnitude (I = P/V), hence section of the copper conductor will be large.

Thus generation, transmission and distribution of D.C. power were restricted to area of few kilometer radius with no interconnections between generating plants. Therefore, area specific generating stations along with its distribution networks had to be used.

In later half of eighties, in nineteenth century, it was proposed to have a power system with 3-phase, 50 Hz A.C generation, transmission and distribution networks.

Once A.C. system was adopted, transmission of large power (MW) at higher transmission voltage become a reality by using transformers. Level of voltage could be changed virtually to any other desired level with transformers – which was hitherto impossible with D.C system.

Filter networks for electrical engineering

A filter is a network designed to pass signals having frequencies within certain bands (called pass-bands) with little attenuation, but greatly attenuates signals within other bands (called attenuation bands or… Read more

    Hi Edvard,

    In street lighting design /or installation? Is the STREET LIGHTING POLE need to be bonded direct to earth for each Pole? is there any specific reference standard?

    please.. provide if there is

    I am looking for sample drawings for Power & Control circuits for a 75kW Soft Starter including PLCs, HMI, Utrasonic level sensors, Utrasonic flow sensors, drive-end and non-drive-end bearing sensors, termistors and associated relays suitable for a Water Pumping Solution

    Dear All,

    I am facing a problem, we have a single 9R32 Wartsila engine and loeri somer alternator. ABB Unitrol 1000-15 A AVR. the generator produces 5.5 kV and then a step up transformer make this 11kv and then step down transformer. the generator trips at overvoltage first stage at 112% at any load during operation.

    Checked following;
    IR for alternator { main stator, main rotor, exciter stator, exciter rotor}
    Diode testing cold and with 24 VDC
    PT IR testing secondary circuit
    resistance with ground
    MCBs replaced
    The star point of the secondary circuit and its grounding.
    the resistance of earting pits
    verified full excitation circuit.
    Everything found normal

    Could anybody help or give an idea or they faced this problem, please respond.

    I need guidance to select the cylindrical insulator for the switchgear.
    (Selection with the formula and IEC standard)

    can you help my?
    Thank you

    Hello every one,

    Q-1: (a) Can some one provide an example of a “T-Connection” from 220 kV to 220 kV transmission line without any normal/required protection equipment and controls?
    (b) What danger this type of connection poses to the TL and all connected the Substations?
    Q-2: Is there a British Electrical Code gives examption from installing Automatic Fire Protection System? Reference please.

    Thank you,

    Dear Sir
    i need to know if there are any international stander for the % of spare line “fully equiped with CB” should be kept inside each switchgear ,switchboard and distribution board?
    also the % of space line ” free of devices” should be kept inside each switchgear ,switchboard and distribution board?

    Good post. I am very interested in electrical repairing work and that is why I like to read blogs about electrical work. Keep updating more and also write more on other topics. Because I love this field I do ac servicing work.

    I would like to know about the Direct Current Motor Starter Design. How do you design the start resistance and the number of them?

    Thank you very much in advance.

    Congratulations for your portal (EEP)
