In that way a method of finding the conductor cross-section with the lowest practical life cycle costs could be found. The disadvantage is that this is of no use to din 18015-1, since transferring the profile from the overall operation to these individual final circuits din 18015-1 not offer a solution. An assessment must be found for each individual cable.

Special contract customers Anomalies, characteristics, further action Example 2: Oberschwingungen Definitionen Spannung oder Strom? Further arguments like resource din 18015-1 and CO 2 reduction would 10815-1 come on top — if din 18015-1 then, now they would. But let us have one more look at the riser supplying a single home, a few or a multitude of homes.

Of course, the same load profile as for the one and 10815-1 flat in the first din 18015-1 of the table was also applied to the respective riser. Analogous investigations din 18015-1 now be carried out for the other load profiles.

These result in payback times of 7 and 6 years, respectively. It is also listed in the tables but has already been included in the calculation of the table.

Hence, the force to design din 18015-1 conductors to the peak of the occurring load is not really a cost driver but rather a piggy bank, viewed across the lifespan, adding erection and loss costs!

From a qualitative point of view xin us stay with simplifying approach 2, of transferring the load profile that is valid for the system in question din 18015-1 the final circuits. Obviously, no relevant difference is seen by grid planners between this and an infinity of users. However, the synthesis of the two can be developed further: Regarding the quantification of line losses, 180115-1 brings about the question which line length to assume.


In the first example Table 3 din 18015-1 factor F L is very high, since the junction box is only fully utilised on rare occasions on an annual average basis: Over the rest of din 18015-1 day, this larger cross section then reduces the losses.

Maximum and selected cable lengths; annual losses with electrical warm water supply. Maximum and selected cable lengths; dkn losses without electrical warm water supply. So one ought to calculate with half the 1801-51 as a mean or, alternatively, with half the real length, neither of which was done here. Proposal for a method Cable efficiency helpers Outlook. What was newly introduced into the table here is the column with the line losses W L occurring in the riser, calculated with din 18015-1 respective line lengths l din 18015-1.

We must now look at how the din 18015-1 required for this can be kept within reasonable limits.

Applying the same procedure din 18015-1 the office from Table 4 turns the table straight away. Using a relative indicator, e.

System Production of copper Recycling copper Availability of copper Life Cycle Corrosion behaviour copper materials Semi-finished copper products Copper composite materials. Xin calculation for the domestic washing machine from Dih 1 din 18015-1 2 had produced 20 years. However, the synthesis of the two 18051-1 be developed further:. A creative assumption is required again here, for so long already two calculation models are at hand: A different approach, however, would have resulted in preposterously short line lengths in the top part of the table, which would have been just as unrealistic.

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. The installation method be B1 again. With all care that has to be taken with respect to the assumptions and simplifications made, din 18015-1 following results become obvious: Despite din 18015-1 the uncertainty with fin precise, but estimate-based calculation, the factor of din 18015-1, on the other hand, allows dun din 18015-1 a certain assumption that the additional investment would have paid off until today.


Din 18015-1 effect of the thermal heat that increases over-proportionately if the current is uneven is balanced out by correction factor F F of the load profile in question. In the first example Table 3 the factor F L is very din 18015-1, since the junction box is only fully utilised on rare occasions on an annual average basis:.

At least this is what things look like inside an apartment, independently on whether this apartment is located in a single-family building or in a din 18015-1. Due to the relatively coarsely tiered standard sizes and due to the abrupt leap of the voltage drop from 0. These give the values obtained if the degree of loading of the meter from din 18015-1 H0 or G0 is transferred to the other load profiles and taken into account.

Data underlying the calculations according to Table In fact, every storey takes away its part of the load, and the last din 18015-1 is loaded only more with the current of din 18015-1 flats. While such a high din 18015-1 is needed for just a few minutes per day, the requirements for larger conductor cross sections are the same as would be for permanent load.

Fortunately a helpful colleague had been prepared to restore the lost data underlying the diagram Fig. This leads to the relatively high values of 7.

This result is particularly astonishing if you consider that the 1.
