How do you calculate the diversity factor of an electrical load?

How do you calculate the diversity factor of an electrical load?

(2) Diversity factor:

  1. Diversity Factor is ratio of the sum of the individual maximum demands of the various sub circuit of a system to the maximum demand of the whole system.
  2. Diversity Factor = Sum of Individual Maximum Demands / Maximum Demand of the System.
  3. Diversity Factor = Installed load / Running load.

What is electrical load diversity?

What is Diversity? Electrical Diversity is a factor applied as an allowance of load not likely to be used at the same time, for example: If load 1 is only used 50% of the time and load 2 is only used the remaining 50% of the time, 10 Amps (Load 1) + 10 Amps (Load 2) = 20 Amps (Total Connected Load), then.

How do you calculate electrical demand load?

Calculating Load

  1. Add together the wattage capacity of all general lighting branch circuits.
  2. Add in the wattage rating of all plug-in outlet circuits.
  3. Add in the wattage rating of all permanent appliances (ranges, dryers, water heaters, etc.)
  4. Subtract 10,000.
  5. Multiply this number by .
  6. Add 10,000.

How do you calculate diversity?


  1. Add the individual species populations to get N .
  2. Determine N × (N – 1) .
  3. Work out n × (n – 1) for each species, where n is the number of individuals in each species.
  4. Sum all the values in step 3.
  5. Divide the sum obtained in step 4 by the value obtained in step 2.
  6. Evaluate Simpson’s diversity index as 1 – D .

Which formula is used to calculate the diversity of?

Diversity factor =Sum of Individual Max. Demand / Max. Demand = 6 Kw / 1.5 Kw =4. Demand Factor = Maximum demand / Total connected load = 1.5 Kw / 12 Kw = 0.125.

How is MD calculated?

Step 1 – Calculate the mean, median or mode value of the given data set. Step 2 – Then we must find the absolute difference between each value in the data set with the mean, ignoring the signs. Step 3 – We then sum up all the deviations. Step 4 – Finally, we find the mean or average of those values found in Step 3.

What is the difference between demand factor and diversity factor?

There is generally confusion between Demand factor and Diversity factor. Demand factors should be ideally applied to individual loads and diversity factor to a group of loads. When you talk about ‘diversity’, there are naturally more than one or many loads involved.

What is the value of diversity factor?

The diversity factor is usually greater than 1; its value also can be 1 which indicates the maximum demand of the individual sub-system occurs simultaneously. Diversity is the relationship between the rated full loads of the equipment downstream of a connection point, and the rated load of the connection point.

How do you calculate percentage diversity?

a) Divide the population of each race/ethnic group by the total population (at both the city level and for each neighborhood). Step 2: a) Divide the population of each race/ethnic group by the total population (at both the city level and for each neighborhood).

What is operating value of diversity factor?

Diversity factor = Sum of individual maximum demands/Max demand on the power station. Since the sum of individual maximum demands is always higher than the maximum demand on power station the diversity factor is always greater than 1.

How is load factor calculated?

Load factor is a measurement of the efficiency of your household’s electrical energy usage. It is calculated by taking the total electricity (kWh) used in the month, divided by your peak demand (kW) multiplied by the number of days in the billing cycle and the total hours in a day.

How is MDI calculated on electricity bill?

Similarly if a motor runs on 1 HP that is 745 Watts you will run in 75% that can be considered as 0.75 power factor. The energy that the appliances have to supply is 1/0.75= 1.33HP. The energy is lost due to the magnetic field in the motor. This is the MDI calculation in electricity bill.

How is load calculated?

Calculating an Electrical Load in a Simple Circuit Let Power = Voltage * Current (P=VI). Let Current = Voltage/Resistance (I=V/R). Apply Kirchoff’s Second Law, that the sum of the voltages around a circuit is zero. Conclude that the load voltage around the simple circuit must be 9 volts.

Can diversity factor be less than 1?

Hence diversity factor is always greater than 1. The knowledge of diversity factor is vital in determining the capacity of the plant equipment. The greater the diversity factor, the lesser is the cost of generation of power.

How is diversity calculated?

The two main factors taken into account when measuring diversity are richness and evenness. Richness is a measure of the number of different kinds of organisms present in a particular area. For example, species richness is the number of different species present.

What is diversity rate?

Category: HR KPIs. The Diversity Rate metric is important for a company because of several reasons. Probably the most important one is the fact that the said company’s brand will be acknowledged by the media and by more people that belong to diverse cultures and ethnicities.

When load factor and diversity factor increases cost of electricity is?

Explanation: Load factor and diversity factor playes an important role in cost of supply of electrical energy. Higher the value of load factor and diversity factor, lower will be the cost per unit generated.
