Development of changes to the construction code of rules in part of updated specific electrical loads

THE PURPOSE. Develop changes to the building code of rules regarding updating the specific calculated electrical loads of multi-apartment residential buildings. Perform a comparative analysis of the power of technological connection of multi-apartment residential buildings, calculated according to regulatory and technical documents and according to those developed on the basis of actual measured data with an assessment of the effect of updating specific design electrical loads.

METHODS. To achieve this goal, mathematical and statistical methods of analysis were used.

RESULTS. Statistical processing of the specific electrical load of apartments in multi-apartment residential buildings in the Moscow region of a cluster of 11–18 floors for twenty-three months of 2021–2023 was carried out, which made it possible to form statistically significant samples by excluding outliers from them and obtaining their basic descriptive statistics. Based on the results obtained, changes were developed to the regulatory and technical document in terms of updating the specific calculated electrical loads of apartments in multi-apartment residential buildings in the Moscow region of the cluster 11 - 18 floors.

CONCLUSION. The introduction of updated values of the specific calculated electrical load will lead to the selection of power transformers with optimal loading, which, on the one hand, will reduce the “locked electrical power”, resulting in reduced electricity losses, and on the other hand, will reduce the cost of technological connection.
