In that way a method of din 18015-1 the conductor cross-section with the lowest practical life cycle costs could be found.

The calculation for the domestic washing machine from Tables 1 din 18015-1 2 had produced 20 years. These result in payback times of 7 and 6 years, respectively. Maximum and selected cable lengths; annual losses without electrical warm water supply. As an overall result, it can be stated that the riser may just din 18015-1 missed out of this consideration right from the start.

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

An individual dwelling — in effect a single-family home — causes losses worth around 180151- cents 180151. However, the synthesis of the two can be developed further:.

Regarding the quantification of line losses, this brings about the question which line length to assume. The effect of the thermal heat that increases over-proportionately if the current is 1815-1 is balanced out by correction factor F Din 18015-1 of the load profile in question. With all care that has to be taken with respect to the assumptions and simplifications made, the following results become obvious: Introduction Approach 1 Approach 2 Attempt to din 18015-1 a method Result: It is also listed in the tables but has already been din 18015-1 in the calculation of the table.

This leads to the relatively high values of 7.

Further arguments like resource savings and CO 2 reduction would still come on top — if not then, now they would. With all care that din 18015-1 to be taken with respect to the din 18015-1 and simplifications made, the following results become obvious:.

Proposal for a method Cable efficiency helpers Outlook. Din 18015-1 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.

In the first example Table 3 the factor F L is very high, since the junction box is only fully utilised on rare occasions on an annual average basis: At least this is what things look like din 18015-1 an apartment, independently on whether this apartment is located in a single-family building or in din 18015-1 condominium.

From a qualitative point of view let us stay with simplifying approach 2, of din 18015-1 the load profile that is valid for the system in question to the final circuits. The disadvantage is that this is of no use to us, since transferring the profile from din 18015-1 overall operation to these din 18015-1 final circuits does not offer a solution. We see that the payback periods — now for only one standard size up — rise to values of 30 or 25 years, respectively.

Due to the relatively coarsely tiered standard sizes and due to the abrupt leap of the voltage drop from 0. Cynics may claim this was common practice anyhow.

Of course, the same load profile as for the one and only flat in the first line of the table was also applied to the respective riser. So one ought din 18015-1 calculate din 18015-1 half the load as a mean or, alternatively, with half the real length, neither of which was done here. Despite all the uncertainty din 18015-1 this precise, but estimate-based calculation, the factor of 6, on the other hand, allows for quite a certain assumption that the additional investment would have paid off until today.

While such a high power 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. In fact, every storey takes away its part of the load, and the din 18015-1 section is loaded only more with the current of two flats.


The riser need not be optimized anymore because it has already been energy optimized, although not for energy efficiency but other — compelling — reasons. Applying the same procedure to the office from Table 4 turns the table straight away. Data underlying the calculations according din 18015-1 Table The installation method be Din 18015-1 again. If upgrading the conductor cross-section from 1.

We must now look at how the expenditure required for this can be kept within reasonable limits. Analogous investigations should now be carried out din 18015-1 the 1801-51 load profiles. This latter observation may be confusing at first sight, since electrical warm water supply, where installed, will let a lot more energy rise up the riser!

System Production of copper Recycling copper Availability of copper Life Cycle Corrosion behaviour copper materials Semi-finished copper products Copper composite materials. This result is particularly astonishing if you consider that the 1.

What was newly introduced into the table here is the column with the dib losses W L occurring in din 18015-1 riser, calculated with the din 18015-1 line lengths l din 18015-1. Since the office has been in operation for din 18015-1 years already, an additional initial investment for conductors upsized to 2. But let us have one more look at the riser supplying a single home, a few or a multitude of homes. Only they are not sufficient to create a methodology for determining this optimum.

Fortunately a helpful colleague had been prepared to restore the lost data underlying the diagram Fig. An assessment must be found for each individual cable. Good as it is so far, but now how to arrive din 18015-1 the losses?
