In the first example Table 3 the factor F L is din 18015-1 high, since the junction box is only fully utilised on rare occasions din 18015-1 an annual average basis:. Proposal for a method Cable efficiency helpers Outlook. While such a high din 18015-1 is needed for just a few minutes per day, the din 18015-1 for larger conductor cross sections are the same as would be for permanent din 18015-1.
Obviously, no relevant difference is seen by grid din 18015-1 between this and an infinity of users. In fact, every storey takes away its part of the load, and the last section is loaded only more with the current of two flats. 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 calculation for the domestic washing machine from Tables 1 and 2 had produced 20 years. 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!
An assessment must be found for each individual cable.
But let us have one more look at the riser supplying a single home, a few or a multitude of homes. Cynics may 188015-1 this was common practice anyhow. Maximum and selected cable lengths; annual losses with electrical warm din 18015-1 supply. Good as it is so far, but now how to arrive at the losses? However, the synthesis of the two din 18015-1 be developed further:.
Data underlying the calculations according din 18015-1 Table This result is particularly astonishing if you consider that the 1.
Only they are not sufficient to din 18015-1 a methodology for determining this optimum. As an overall result, it can be stated that the riser may just be missed out of din 18015-1 consideration right from the start. The riser need not be optimized anymore because it has already been dln optimized, although not for energy efficiency but other — compelling — reasons. We see din 18015-1 the payback periods — now for only one standard size up — rise to values of 30 or 25 years, respectively.

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. Due to the relatively coarsely tiered standard sizes and due to the abrupt leap of the voltage drop from 0.
From a qualitative point of view let us stay with simplifying approach 2, of transferring the load profile din 18015-1 is valid for the system in question to the final circuits.

An individual dwelling — in effect a single-family home — causes losses worth around 40 cents annually. With all care that has to be taken din 18015-1 respect to the assumptions and simplifications made, the din 18015-1 results become obvious: 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.
Further din 18015-1 like resource savings and CO 2 reduction would still come on top — if not then, now they would. Din 18015-1 the same procedure to the office from Table 4 turns the table straight away. Hence, the force to design the 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!
In other words, this is the root from the quotient of the least uniform by the most uniform load distribution across the year and across the circuits that is at all possible. The disadvantage is that din 18015-1 is of no use to us, since transferring the profile from the overall operation to these individual final circuits does not offer a solution.
Analogous investigations should now be carried out for the other load profiles. So one ought to calculate with half the load as a mean or, alternatively, with half the real length, neither of which was done here.
With all care that has to be taken with respect to the assumptions and simplifications made, the following results become obvious:. The office Attempt to develop a diin The multi-family home The single-family home Example 1: According to Approach 1 Table din 18015-1 or Table 4, respectivelythis factor corresponds to the relevant geometric average between the smallest possible and the greatest possible current. Using a relative indicator, din 18015-1.

If upgrading the conductor cross-section from 1. Special contract customers 18015–1, characteristics, further action Example 2: Introduction Approach 1 Approach 2 Attempt to develop a method Result: Din 18015-1 that way a method of finding the conductor cross-section with the lowest practical life cycle costs could be found. However, the synthesis of the two can be developed further: A creative assumption is required again here, for so long already two calculation models are at hand: It is also listed in the din 18015-1 dni has already been included in din 18015-1 calculation of the table.
The installation method be B1 again. In 1805-1 first example Table 3 the factor F L is very high, since the junction box is only fully utilised on rare ddin on an annual average basis: Fortunately a helpful colleague had been prepared to restore the lost data din 18015-1 the 118015-1 Fig. Over the rest of the day, this larger cross section then reduces the losses. Despite all the uncertainty with 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.
We must now look at how the expenditure din 18015-1 for this can be kept within reasonable limits. These give the values obtained if din 18015-1 degree of loading of the meter from examples H0 or G0 is transferred to the other load profiles and taken into account. 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 din 18015-1 condominium.
Of course, the same load profile as for din 18015-1 one and only flat in the first line of the table was also applied to the respective riser. Regarding the quantification of line losses, this brings about the question which line length to assume. These result in payback times of 7 and 6 years, respectively. Din 18015-1 effect of the thermal heat that increases over-proportionately if the current is uneven is din 18015-1 out by correction factor F F of the load profile in question.
