An assessment must be found for each individual cable. Special contract customers Anomalies, characteristics, further action Dn 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.

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

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

Over the rest of the day, this larger cross section then reduces the losses. An individual dwelling — in effect a single-family home — causes losses worth around 40 cents annually. Using a relative indicator, e.

Electrical installations in residential buildings – Part 1: Planning principles

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. Regarding the quantification of line losses, this brings about the question which line length to assume. The installation method be B1 again. At least this is what things look like inside an apartment, independently on whether 1805-1 apartment is located in a single-family building or in a condominium.

We see that the payback periods — now for only one standard size up — rise to values of 30 or 25 years, respectively. In the first example Table 3 the factor F L is very high, since 180151 junction box is only fully utilised on rare occasions on an annual average basis: This leads to the relatively high values of 7.


Deutsches Kupferinstitut: Cable efficieny method

Maximum and selected cable lengths; annual losses with electrical warm water supply. Proposal for a method Cable efficiency helpers Outlook. Data underlying the calculations according to Table System Production of copper Recycling copper 1815-1 of copper Life Cycle Corrosion behaviour copper materials Semi-finished copper products Copper composite materials.

With all care that has to be taken with respect to the assumptions and simplifications made, the following results become obvious:. Fortunately a helpful colleague had been prepared to restore the lost data underlying the diagram Fig.

Maximum and selected cable lengths; annual losses without electrical warm water supply.

Applying the same procedure to the office from Table 4 turns the table straight away. The office Attempt to develop a method The multi-family home The single-family home Example 1: 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.

The disadvantage 18015- 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.

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.

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. 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. Oberschwingungen Definitionen Spannung oder Strom? 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. It is also listed in the tables but has already been included in the calculation 1805-1 the table.


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.

According 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. Since the office has been in operation for 33 years already, an additional initial investment for conductors upsized to 2.

Introduction Approach 1 Approach 2 Attempt to develop a method Result: 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.

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

Fluorescent Magnetic ballasts principle Magnetic ballast disturbances Compensation Electronic ballasts principle Electronic ballast disturbances Fluorescent lamp efficiency Leuchtstofflampen-Quecksilber. But let us have one more look at the riser supplying a single home, a few or a multitude of homes.

As an overall result, it can be stated that the riser may just be missed out of this consideration right from the start. Good as it is so far, but now how to arrive at the losses? If upgrading the conductor cross-section from 1. The calculation for the domestic washing machine from Tables 1 and 2 idn produced 20 years.

Cynics may claim this was common practice anyhow. Obviously, no relevant difference is seen by grid planners between this and an infinity of users. 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.

Due to the relatively coarsely tiered standard sizes and 18051-1 to the abrupt leap of the voltage drop from 0.
