Sorry for my assumptions and thank you for the explanation.
-"less than 10 KVA, the next available demand." so from 5kVA it jump to 10kVA to the power one can contract? Do you have some info or reference of those available demand? I guess it- would depend on the distribution operator...
@waross
35A for a three-phase system 400V would be 24kVA. So they installed at the meter a 35A to trip if you exceed 24kVA have a contract of 5kVA?
Other thing, how can you access to the breaker of the energy meet if that is supposed to be inaccessible by other except the electricity supplier?
"nowadays our customers are not interrupted or limited at all during the cold winter months"
Say a distribution cable feed 8 costumers(households). If there is unlimited power usage by the costumer, how do the operator prevent that the power used by all the costumers (perhaps coincide at their...
Maybe someone who works in a distribution operator/company can clarify the following to me?
A household connected to a LV grid get a contract based on the peak power they are expected to consumed. I guess, the operator estimated the power in the number of people living in the household, or if...
I have seen two max values for cables, why are there two values, which one should I use for general purposes. For instance in this when,you can see two values: https://www.altestore.com/howto/maximum-ampacity-current-capacity-for-wire-and-cable-a108/
I had a quick look at the measurements of a distribution transformer for a time period of a month with a resolution of 10 minutes, and there were currents of the order of 170A in each phase, and with an imbalance on the range of 1-10 A, and with the neutral current in the range of 1-4A. I really...
How much is expected to be the neutral current read at a distribution substation of lets say 400kVA 10kV/400V, for a "normal" residential area, either in Europe or the USA. Any idea?
Thanks in advance.
What does contain the details data you give to TSO basically? As I understand, some countries have set themselves targets of PV annual production (some relay basically on household production) for future years, so if they what to increase their production by XXX by the year YYY, then they have...
@7anoter4 In your calculation, whv/wlv=30/(0.4/sqrt(3)=129.9, but I would say it is rather whv/wlv=30/0.4=75 since, to my knowledge, the ratios of the transformers always are given referring to line-to-line values.
Hi, my question is how Distribution System Operators(DSO) of a country/region estimate how much PV production is obtained from Households? I am not sure if they collect this data from smart meters, or if they somehow estimated it. For instance if the installed PV capacity is known, is it...
