Fortunately a helpful colleague had been prepared to restore the lost data underlying the diagram Fig. Due to the relatively coarsely tiered standard sizes and due to the abrupt leap of the voltage drop from 0.

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. 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.

Since the office has been in operation for 33 years already, an additional initial investment for conductors upsized to 2. Maximum and selected cable lengths; annual losses with electrical warm water supply. These result in payback times of 7 and 6 years, respectively. Fluorescent Magnetic ballasts principle Magnetic ballast disturbances Compensation Electronic ballasts principle Electronic ballast disturbances Fluorescent lamp efficiency Leuchtstofflampen-Quecksilber.

Proposal for a method Cable efficiency helpers Outlook. Using a relative indicator, e. 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: Analogous investigations should now be carried out for the other load profiles. Obviously, no relevant difference is seen by grid planners between this and 18051-1 infinity of users.

This result is particularly astonishing if you consider that the 1. 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 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. Over the rest of the day, this larger cross section then reduces the losses. What was newly introduced into the table here is the column with the line losses W L occurring in the riser, calculated with the ddin line lengths l select.

As an overall result, it can be stated that the riser may just be missed out of this consideration right from the start. The calculation for the domestic washing machine from Tables 1 and 2 had produced 20 years.

If upgrading the conductor cross-section from 1. 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.

An individual dwelling — in effect a single-family home — causes losses worth around 40 cents annually.

Further arguments like resource savings and CO 2 reduction would still come on top — if not then, now they would. However, the synthesis of the two can be developed further: With all care that has to be taken with respect to the assumptions and simplifications made, the following results become obvious:.

Even if the mentioned guesswork should be by a whole magnitude in error, this would not change anything about the result. Regarding the quantification of line losses, this brings about the question which line length to assume. Special contract customers Anomalies, characteristics, further action Example 2: An assessment must be found for each individual cable. 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!

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. 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.

Deutsches Kupferinstitut: Cable efficieny method

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! With all care that has to be taken with respect to the assumptions and simplifications made, the following results become obvious: Applying the same procedure to the office from Table 4 turns the table straight away. This being so, the estimate is quite likely to be still too high, since all risers have been calculated as being loaded with 180115-1 entire current drawn by the building.

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.

Data underlying the calculations according to Table 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 that way a method of finding the conductor cross-section with the lowest practical life cycle costs could be found.

Good as it is so far, but now how to arrive at the losses? Maximum and selected cable lengths; annual losses without electrical warm water supply. We must now look at how the expenditure required for this can be kept within reasonable limits. Introduction Approach 1 Approach 2 Attempt to develop a method Result: The office Attempt to develop a method The multi-family home The single-family home Example 1: 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.
