    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,

    Yogin

    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?

    hello sir,

    Please clear my confusion. While calculating load currents for sizing the cables, which P.F.should be used?? Old or new after compensation..? and also i heard that reduced cable size depends on the type of compensation.i.e. global, sector or individual…please explain.


    • Abhiram
      Dec 21, 2016

      Hello,

      If you are talking about XLPE cables, then the power factor to be selected as per the load type. If it is residential, then you can go to 0.8 or below ; if it is commercial/ industrial you have to go to 0.9 or unity (If full motor/ pump loads).
      You can select/ alter the PF as per the local authority approvals only.

      For Fire pumps, large motors & AC units(with motor) always consider starting current as 1.5 times the normal load as standard to size the MCCB/ Isolator rating & then select the cable size accordingly.

    Sory I can not donate at this moment, But this
    Engineering portal really deserve a donation just
    as many other wonderful sites on the WEB.
    please dont give up our portal. Keep on.
    Great Thanks to you all.

    I want to know about the current and voltage role in human body killing (death and electric shuck). I studied many articless/books about it but some are saying current kill people while some are stating voltage. In my opinion it is frequency as in our country frequency is 50Hz and voltage is 220 P-P. It usually kill people while electrocuted. In the country I am working the frequency is 60Hz and the voltage is same 220 P-P and I did not hear that some one electrocuted and died.

    As we go down in reducing frequency the system is going to DC nature which is more danger than AC.

    Please explain so that I can make clear my concept.

    Good day, first of all i would like to congratulate all of you for such an amazing portal. Contributions are great and i feel like i can keep learning each day a little bit more. I do have one request to make, if possible. I am currently working my thesis and i am interested in power quality for a call center building; specifically i am looking for information about the IEEE.Std. 1100. If you could share something it would be great. Greetings and keep up the great job!!!

    Hi sir..
    I am having confusion in selection of alternate motor against the installed one.Here i will give the details of installed & alternate motor which i decided for procurement.

    Installed 3 phase Squirrel cage IM:
    Supply Voltage=415v; P=22Kw; Rated Torque=131.7Nm; speed=1468rpm; Frame Size=180L; Rated Current=37.2A(VFD duty Motor); NDE bearings=6210 ZC3 ;DE bearings=6210 ZC3; Cooling Method=IC416 ;

    Proposed 3 phase Squirrel cage IM:

    Supply Voltage=415v; P=22Kw; Rated Torque=143Nm; speed=1473rpm; Frame Size=180L; Rated Current=38A; NDE bearings=6310 ZC3 ;DE bearings=6310 ZC3; Cooling Method=IC411 ;
    Kindly suggest me to procure the proposed one or not and request you to give the detailed articles regarding selection of different motors with known motor.
