What is Electrical Load Data Analysis?

Electrical Load Data Analysis

In industrial projects, electrical design consultants are an essential part of the project team from the beginning. Electrical design starts with the collection of inputs for the load. 

To start with the electrical consultants estimate the electricity requirements for the factory. Then, the type of input voltage is considered for the electrical installation whether it is HT or LT. It makes it critical for electrical consultants to study the electrical load data for the manufacturing facility. 

What is electrical load?

An electrical load is a component of a circuit that consumes power. The first step in electrical design is invariably to list all the electrical loads proposed in the factory. 


Electrical Load Data

Components of a typical electrical load list?

The components in a list vary depending on the project and the electrical design consultants. Some of the items on the list are as follows:

  1. Equipment
  2. Number of machines
  3. Requirement of power for each machine
  4. Usage: intermittent, continuous, emergency
  5. Diversity factor
  6. Power factor
  7. Rated load per machine. 

After analyzing the electrical load, the electrical consultants decide on the load requirement, the installed load, load factor, diversity factor, maximum demand, connected load, etc. This helps finalize the type of power. Another factor that the consultants take into consideration is the local codes and power tariffs and policies.

What are the key deliverables along with the electrical load data analysis?

The electrical load data analysis has the following deliverables.

  1. Load Calculation 
  2. Load Factor Calculations
  3. Calculations for diversity factors
  4. Maximum Demand Calculation
  5. Installed and Contract Load Calculation
  6. Sizing of electrical installation 
  7. Sizing of the transformer 
  8. Block Diagrams
  9. Block Estimates
  10. Primary Consultation Report

Conclusion

Finally, the electrical consultants create the load data, analyze it and arrive at an optimized power requirement and an adequately sized transformer. The resultant electrical design for the industrial facility will be optimal.
