Load Data Analysis
In an industrial infrastructure project, electrical engineering consultants or designer forms an essential part of the team. The electrical consultant typically starts the project by collecting all information regarding the electrical load.
Firstly, industrial electrical engineering consultants have to estimate how much electricity to required for the industrial infrastructure project. Secondly, the electrical consultants must determine the type of input voltage (HT or LT) to use on a routine basis for an electrical installation. Therefore, a thorough analysis of the electrical load data is needed for any industrial project.
Electrical Load
An electrical load is referred to as the component of a circuit that consumes power. In electrical design, the first step in an industrial project is to list out all the electrical load required in that facility in a load table.
Components of a typical list
The components in a list depend on the electrical consultant. However, some of the typical items in the list are as follows:
- Equipment
- Number of machines
- Power requirement
- Type of usage: continuous, emergency, intermittent, etc
- Power factor
- Diversity Factor
- Rated load per machine
The industrial electrical engineering consultants or designers will analyze the data. Subsequently, the industrial electrical consultants decide the load requirement installed load, load factor, diversity factor, steady-state demand, maximum demand, connected load etc. As a result, the type of power can be finalized. Additionally, the electrical consultants have to check the data along with the local codes and tariff policies.
A High Tension service connection requires the sizing and design of consumer side substation (Indoor/Outdoor), sizing of transformers & switching equipment. The HT tariff is applicable in such cases. Similarly, Low Tension installations are normally connected to the local network using proper isolation and protective equipment. The LT tariff is applicable.
Key Deliverables:
The electrical load data analysis has the following deliverables.
- Load Calculation
- Load Factor Calculations
- Diversity factor Calculations
- Maximum Demand Calculation
- Installed and Contract Load Calculation
- Electrical Installation Sizing
- Transformer Sizing
- Block Diagrams
- Block Estimates
- Primary Consultation Report
To conclude, creating electrical load data and analyzing it is essential. Accordingly, the electrical engineering consultants or designers can arrive at an optimized power requirement and a properly sized transformer. As a result, the electrical design for the industrial facility will be optimal.
