Calculating Commercial Electrical Loads: A Crucial Task in Modern Construction

In today's fast-paced construction industry, calculating electrical loads accurately has become a critical task. This is especially true when it comes to residential buildings and public facilities. Over the past decade, there has been a significant increase in the commissioning of apartment buildings in Kazan, with a notable trend towards taller structures. In this article, we will explore the importance of accurate commercial electrical load calculation sheets and discuss ways to improve efficiency in construction and operation.

Grouping Residential Buildings by Electrical Capacity

Recent studies have identified three distinct groups of residential buildings based on their electrical capacity: those without elevators and gas stoves, those with elevators and gas stoves, and those with elevators and electric stoves. This categorization is crucial for determining the appropriate electrical load calculation sheet to use.

Monitoring Electric Loads

To improve efficiency in construction and operation, it is essential to monitor electric loads and update standard documents accordingly. By doing so, calculated values can be brought closer to actual ones, reducing losses in power transformers and increasing economic efficiency.

Low Load of Power Transformers: A Common Problem

In many cases, power transformers operate at a low load, leading to increased losses and inefficient use of investments. To mitigate this issue, it is recommended that the capacity of power transformers be selected based on account 70% of the total maximum load in the rated mode.

Research on TS Loading

Recent research conducted by the Association 'Roselektromontazh' has shown that approximately 80% of TS devices operate with a maximum load of less than 30% during the year. This highlights the need for more accurate calculations to avoid overloading and underloading of electrical systems.

Actual Load vs Calculated Load

Practical experience has demonstrated that actual loads are often significantly lower than calculated loads, typically ranging between 1.5 to 2.5 times less. This emphasizes the importance of using standard specific load values to calculate power consumption for residential and public buildings.

In conclusion, accurate commercial electrical load calculation sheets are essential for efficient construction and operation of power grid complexes. By monitoring electric loads, updating standard documents, and selecting suitable transformer capacities, we can reduce losses and increase economic efficiency in the industry.
