Usually, real balance is determined following values of load (load):
- Full load;
- Load current conducted in the period;
- Minimum load current conducted in the period;
- Load average annual effective operating periods.
Where you cannot create conditions for the execution of the tasks above balance sheet, shall be elected at least three sizes of pregnancy, its normal range of variation, which is producing the balance sheet. For almost constant pregnancy, the balance is running only for this task.
If the energy consumption or production are influenced sensitive parameters (characteristics of raw materials, outside temperature, etc.), The balance is running for a few characteristic sizes of these parameters (size limit, average, normal). Technical condition and cleaning equipment or installation will be, as appropriate, the following:
- To develop real balance, equipment (or facility) will be in normal state (state average wear);
- To develop balance and the receiving approval, equipment (or facility) will be perfectly clean.
Depending on the nature of technology, energy balance can be drawn hourly cycle, batch or per unit of product produced. In order to take into account as many factors that influence the elements of a balance (energy in various parts of the contour, energy contour generated by exothermic reactions, the energy used in good shape, the energy delivered outside contour to be used in other shapes, the energy loss), it will draw a bigger calendar period, usually one year.
For reception or approval be made only balances plant schedules or cycles, no annual accounts are running. Determining the balance sheet required quantities will be based on direct measurements. If the size can be determined directly, but can be inferred with sufficient accuracy by measuring other quantities, is allowed to apply the method of indirect measurements.
Some elements of the balance can be neglected if their determination involves considerable difficulties and is less than 1% of all incoming and outgoing energy. These elements enter into the "correlation of balance", which shall not exceed 2.5% of total incoming energy.
Devices used for measurement must have under metrological standards. The values of process parameters and operating energy balance and events occurring during the measurements will be recorded in the records.
