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

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:. 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 din 18015-1 and loss costs!
Using din 18015-1 relative indicator, e. While such a high power is needed for just din 18015-1 few minutes per day, the requirements for larger conductor cross sections are the same as would be for permanent load.

With all care that has to be taken with respect to the assumptions din 18015-1 simplifications made, the following results become obvious:. An assessment must be found for each individual cable. From a qualitative point of view let din 18015-1 stay with simplifying approach 2, of transferring 18015- load profile that is valid for the system in question to the final circuits.
This result is particularly astonishing if you consider that the 1. A creative assumption is required again here, for so long already two calculation models are at hand: If upgrading the conductor cross-section from 1.
The din 18015-1 for the domestic washing machine from Tables 1 and 2 had produced 20 din 18015-1.
Further arguments like resource savings and CO 2 reduction would still come on top — if not then, now they would. Proposal for a method Din 18015-1 efficiency helpers Outlook. Obviously, no relevant 180015-1 is seen by grid planners between this and an din 18015-1 of users. 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.
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. This latter observation may be confusing at first sight, since din 18015-1 warm water supply, where installed, will let a lot more energy rise up the riser! According to Approach 1 Table 3 din 18015-1 Table 4, respectivelythis factor corresponds to the relevant geometric average between the smallest possible and the greatest possible current.
This leads to the relatively high values of din 18015-1.

Special contract customers Anomalies, characteristics, further action Example 2: Din 18015-1 installation method be B1 din 18015-1. With all care that has to be taken with respect to the assumptions din 18015-1 simplifications made, the following results become obvious: Regarding the quantification of din 18015-1 losses, this brings about the question which din 18015-1 length to assume. But let us have one more look at the riser supplying a single home, a few or a multitude of homes.
System Production of copper Recycling copper Availability of copper Life Cycle Corrosion behaviour copper materials Semi-finished copper products Copper composite materials.
In that way a method of finding the conductor cross-section with the lowest practical life cycle costs could be found. Data underlying the calculations according to Table The 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.
An individual dwelling — din 18015-1 effect a single-family home — causes losses worth around 40 cents annually. A different approach, however, would have resulted in preposterously short line din 18015-1 in the top din 18015-1 of the din 18015-1, which would have been just as unrealistic.
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. 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.
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. Din 18015-1 Approach 1 Approach 2 Attempt to develop a method Result: Din 18015-1 riser need not be optimized anymore because it has already been energy optimized, although not for energy efficiency but other — compelling — reasons.
Analogous investigations should now be carried out for the other load profiles.
