These give the values xin 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.

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. 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 don profile in question.

Introduction Approach 1 Approach 2 Attempt to develop a method Result: Fortunately a helpful colleague had been prepared to restore the lost data underlying the diagram Fig.

System Production of copper Recycling copper Availability of copper Life Cycle Corrosion behaviour copper materials Semi-finished copper products Copper composite materials. Over the rest of the day, this larger cross section then reduces the losses.

This result is particularly astonishing if you consider that the 1. However, the synthesis of the two can be developed further: An individual dwelling — in effect a single-family home — causes losses worth around 40 cents annually. 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!

Applying the same procedure to the office from Table 4 turns the table straight away. While such a high power is needed 81015-1 just a few minutes per 180151, the requirements for larger conductor cross sections are the same as would be for permanent load.

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 diin final circuits.

This leads to the relatively high values of 7. 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. However, the synthesis of the two can be developed further:.

The installation method be B1 again. As an overall result, it can be stated that the riser may just be missed out of this consideration right from the start. Even if the mentioned guesswork should be by a whole magnitude in error, this would not change anything about the result.

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 ein until today. Fin underlying the calculations according to Table These result in payback times of 7 and 6 years, respectively.

But let us have one more look at the riser supplying a single home, a few or a multitude of homes. 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 18015- first example Table 3 the factor F L is very high, 180151- the junction box is only fully utilised on rare occasions on an annual average basis: Fluorescent Magnetic ballasts principle Magnetic ballast disturbances Compensation Electronic ballasts principle Electronic ballast disturbances Fluorescent lamp efficiency Leuchtstofflampen-Quecksilber.

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

Only they are not sufficient to create a methodology for determining this optimum. 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. Maximum and selected cable lengths; annual losses with electrical warm water supply.

The riser need not be optimized anymore because it has already 18051-1 energy optimized, although not for energy efficiency but other — compelling — reasons. Obviously, no relevant difference is seen by grid planners between this and an infinity of users. We must now look at how the expenditure required for this can be kept within reasonable limits.

The calculation for the domestic washing machine from Tables 1 and 2 had produced 20 years. If upgrading the conductor cross-section from 1.

Due to 180115-1 relatively coarsely tiered standard sizes and due to the abrupt leap of the voltage drop from 0. 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:.
