Calculation of Electrical Load and Panel Energy Consumption

Electrical load calculation and energy consumption

This MS Excel spreadsheet calculates the following //

  • Continuous and non-continuous electrical load of panel
  • Total energy consumption (KWH) in daily/monthly of panel
  • Size of MCB of each branch circuit of panel
  • Voltage / Voltage difference of each phase
  • Unbalanced load in neutral wire
  • Expected temperature rise in each phase
  • Load in each phase
  • Starting / full load / continuous / non-continuous load
  • Size / type / tripping setting of main MCCB

    Great reference and time saver tool when performing such tedious tasks! Test and sample a calculation, use with caution.

    You are kindly requested to check your definition of diversity factor. In electrical engineering there is no diversity factor less than one but you use 0.80. This will totally affect your whole computation. if you find any diversity less than one please email me where you got it.

      Just noted the reference in the comments made to diversity factor: the article and associated spreadsheet is correct in using a diversity factor of 0.8 (diversity of 1 (unity) is possible in theory). If the case that a diversity factor was never less than 1 than there would be no need to ever apply a diversity factor!

    Hi These spreadsheet looks really great help to electrical engineers. I am able to see them on ipad but could not download on laptop. Can anyone suggest how to do it on laptop.

    Great site. Thank you for your willingness to share what you have and saving our time in reinventing the wheel.

    This is preethy.Can you please help me in providing formulas for the below.

    Suppose for 1HP feeder Amps is 2 & contactor is 7,OLR range is 2.2-3.2.

    How can these valves be calculated by using formula.

    It is great and handy calculator with one exception. That is when calculating the total monthly consumption, the number of hours per day is used twice in the calculation. Please see below for details.

    Average Using/ Day (Hours) Average Using/ Month (Hours) No of Unit Consumed/Day No of Unit Consumed/Month
    18 540 900 486000
    10 300 350 105000

      EEP4JOE: Like you, I believe the formulas in Column “U” (# Units Consumed Per Month) are incorrect.

      For example “U13” formula is “=P13*S13*R13”. The value in Cell “S13” is already calculated as a monthly value. Multiplying “S13” by “R13” results in “U13” multiplying the daily use twice.

      Since the cells in Column “U” are protected, only the author can correct the problem..

    Excellent. Will be very useful in load calculation.

    VERY WELL DONE!

  11. […] from the start that the electric systems be correctly based on realistic load data or best possible typical load estimates, or both because all final, finite load data are not available during the preliminary […]
