How to prove that in 3 days the counter could not wind 13400 kVA?
Hello, I installed a new electric meter Mercury 201.5 (a private house, a meter on a power transmission pole). Three days later, the readings amounted to 13,400 kVA (over the past 10 years, the average monthly indicator was 200-300 kVA). Conducted verification-recognized marriage counter. Recalculation of TNS-energy refused to do. Court. By what formula can one prove in court that a meter is not able to miss such a stream of energy in three days? thank

That is, according to the logic of TNS-energo, in three days you consumed 60 monthly average indicators? How much power do you have?
Option 1, logically, let's say your allocated power is 10 kVA. So you can simultaneously connect devices up to 10 kVA, without triggering protective equipment. Then, if there is 24 hours in a day, you could consume 240 kVA for them, for three days 240 * 3 = 720 kVA. With their “readings” you consumed 13400/3 = 4466 kVA per day and 186 kVA per hour, and the number of energy released is the same or less.
The second option is according to the current of the counter, you have Mercury 201.5, this model has the following characteristics: it has a base current of 5 A and a maximum of 60 A. Then it could take into account up to 220 * 60 = 13.2 kVA at a time, although this counter only takes into account active energy, that is, kW, but omit this moment. Then 13.2 * 24 = 316 kVA per day and 950 kVA in three days - and again less than YOU wrote.
This article describes the characteristics of these counters. https://my.electricianexp.com/en/obzor-elektroschetchika-merkurij-201.html. And a way for those who are completely desperate, if there is an opportunity to climb a pole and calculate the number of impulses at a known load, you can see how much it really shakes. This meter should have 3200 pulses per kWh. With a load of one kW in 1 minute, there should be 3200/60 = 53. (3) pulses. That is almost 1 time per second.
