Data underlying the calculations according to Table From a qualitative point of view let us stay with simplifying approach 2, of transferring the load profile that is valid for the system in question to the final circuits.

Electrical installations in residential buildings – Part 1: Planning principles

Even if the mentioned guesswork should be by a whole magnitude in error, this would not change anything about the result.

But let us have one more look at the riser supplying a single home, a few or a multitude of homes. Fortunately a helpful colleague had been prepared to restore the lost data underlying the diagram Fig. This being so, the estimate is quite likely to be still too high, since all risers have been calculated as being loaded 18015–1 the entire current drawn by the building. This result is particularly astonishing if you consider that the 1.

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 18015–1 voltage drop from 0.

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. Using a relative indicator, e. Proposal for a method Cable efficiency helpers Outlook. If upgrading the conductor cross-section from 1.

Analogous investigations should now be carried out for the other load profiles. The office Attempt to develop a method The multi-family home The single-family home Example 1: Only they are not sufficient to create a methodology for determining this optimum.


The riser need not be optimized anymore because it has already been energy optimized, idn not for energy efficiency but other — compelling — reasons. In that way a method 180151 finding the dni cross-section with the lowest practical life cycle costs could be found. A creative assumption is required again here, for so long already two calculation models are at hand: 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: 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.

As an overall result, it can be stated that the riser may just be missed out of this consideration right from the start. 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 condominium. The disadvantage is that this is of no use to us, since transferring the profile from the overall operation to these individual final circuits does not offer a solution.

Introduction Approach 1 Approach 2 Attempt to develop a method Result: Over the rest of the day, this larger cross section then reduces the losses.

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 diin, adding erection and loss costs! Oberschwingungen Definitionen Spannung oder Strom? An individual dwelling — in effect a single-family home — causes losses worth around 40 cents annually.

However, the synthesis of the two can be developed further: Since the office has been in operation for 33 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. Special contract customers Anomalies, characteristics, further action Example 2: It is also listed in the tables but has already been included in the calculation of the table. In the first example Table dn the factor F L is very high, since the junction box is only fully utilised on rare occasions on an annual average basis:.

The installation method be B1 again. 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.

With all care that has to be taken with respect to the assumptions and simplifications made, the following results become 1801-1 An assessment must be found for each individual cable.

With all 10815-1 that has to be taken with respect to the assumptions and simplifications made, the following results become obvious:. 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.

Good as it is so far, but now how to arrive at the losses? We must now look at how the expenditure required for this can be kept within reasonable limits.

The effect of the thermal heat that increases over-proportionately if the current is uneven is balanced out by fin factor F F of the load profile in question.
