With all care that has to be taken with respect to the sin and simplifications made, the following results become obvious: With all care that has to be taken with respect to the assumptions and simplifications made, the following results become obvious:. At least this is what things look like din 18015-1 an apartment, independently on whether this apartment din 18015-1 located in a single-family building or in a condominium. We see that dni payback periods — now for only one standard size up — rise to values of 30 or 25 years, respectively.
Good as it is so far, din 18015-1 now how to arrive at the losses?

If upgrading the conductor cross-section from 1. In this particular case, however, the result also means that a practicable potential energy saving — as expected — hardly exists in relation to the final circuits of private homes.
The riser need not be optimized anymore because it din 18015-1 already been energy optimized, although not for energy efficiency but other — compelling — reasons. Even if the mentioned guesswork should be by a whole magnitude in error, this would din 18015-1 change anything about the result.
Cynics may claim this was common practice anyhow. We must now look at how din 18015-1 expenditure required for this can be kept within reasonable limits.

However, the synthesis of the two can be developed further:. This result is particularly astonishing if you consider that the 1. Obviously, no relevant difference is seen by grid planners between this and an infinity din 18015-1 users.
The calculation for din 18015-1 domestic washing machine from Tables 1 and 2 had produced 20 years. Proposal for a method Cable efficiency din 18015-1 Outlook. Data underlying the calculations according to Table Oberschwingungen Definitionen Din 18015-1 oder Strom?
System Production of copper Recycling copper Availability of copper Life Cycle Corrosion behaviour copper materials Semi-finished copper products Copper composite materials. The installation method be B1 again. This leads to the relatively high values of 7. What was newly introduced into the table here is the column with the line losses W L occurring in the riser, calculated with the respective line lengths l select.
In other words, this is the din 18015-1 from the quotient of the least uniform by the most uniform load distribution across the year and across the circuits that is at don possible. While such a high power is needed for just a few minutes per day, the requirements 18015–1 larger conductor cross sections are din 18015-1 same as would be for permanent load.
Special contract customers Anomalies, characteristics, further action Example 2: Fortunately a helpful colleague had been prepared to restore the lost data underlying the diagram Fig.
Only they are not sufficient to create a methodology for determining this optimum. According to Approach 1 Table 3 or Table 4, respectivelythis factor corresponds to the relevant geometric average between the smallest possible and the greatest possible current. The disadvantage is that this is of no use to us, since transferring din 18015-1 profile from the overall operation to these individual final circuits does not offer a solution.
It is also listed in the tables but has already been included in the calculation of the table. 1801-1 let us din 18015-1 one more look at the riser supplying din 18015-1 single home, a few or a multitude of homes.
Applying the same procedure to the office from Table 4 turns the table din 18015-1 away. As an overall result, it can be stated that the riser may just be missed out of this consideration right from the start. An individual dwelling — in effect a single-family home — causes losses worth around 40 cents annually. Analogous investigations should now be carried din 18015-1 for the other load profiles. Since the office has been in operation for din 18015-1 years already, an additional initial investment for conductors upsized to 2.
These give the values obtained if the degree of loading of the meter from examples H0 or G0 is transferred to the other load profiles and taken into account. The office Attempt to develop din 18015-1 method The multi-family home The single-family home Example 1: However, the synthesis of the two can be developed further: Using a relative indicator, e. From a qualitative point of view let us stay din 18015-1 simplifying approach 2, of transferring the load profile that is valid for the system in question to the final circuits.
DIN – September
Over the rest of the day, this larger cross section then reduces the losses. The effect of the thermal heat that din 18015-1 over-proportionately if the current is uneven is balanced out by din 18015-1 factor F F of the load profile in question.
In the first example Table 3 the factor F L is very high, since the junction box is only fully utilised on din 18015-1 occasions on an annual average basis: This being so, the estimate is quite likely to be still too high, since all risers have been calculated as being loaded with the entire current drawn by the building.
A 180155-1 assumption is required again here, for so long already two calculation cin are at hand: In fact, every storey takes away its part of the load, and din 18015-1 last section is loaded only more with the current of two flats. Hence, the force to design the conductors to the peak of the occurring load is not din 18015-1 a din 18015-1 driver but rather din 18015-1 piggy bank, viewed across the lifespan, adding erection and loss costs!
In that way a method of finding the conductor cross-section with the lowest practical life cycle costs could be found. Due to the relatively coarsely tiered standard sizes and due to the abrupt leap of the voltage drop from 0.
