KS Diversity Factor is not considered in sizing cables/breaker/transformer

[EDBAS]

The above topic has been marked as solved in a thread, However, in the latest version V2 released this May 2024. The above subject is still not resolved.

Hello,

There was an issue in managing the given values (while opening the project file) and this has been fixed during the last release.

Can you please provide some additional information.

Hello EDBAS,

For answering your query, 

Diversity factors are considered during modifying of Ks.

Transformer, Cables, Circuit breakers & upstream current (Ib) changing based on diversity factors on each level of busbars/Panels.

For that We have done analysis of 2 perspectives (Enabling operating modes for different diversity factors & Creating 2 projects in same range and different diversity factors).

Case 1: -

Diversity factors are considered during modifying of Ks, upstream current (Ib) changing based on diversity factors on each level of busbars/Panels.

For example, we have created trial projects with 3 operating conditions with

1. Normal operating mode with full load i.e., Ks= 1.
2. Working with 50% load i.e., Ks =0.5.
3. Working with 70% load i.e., Ks =0.7.

We can see below for all the operating modes Transformer/Cable/Upstream circuit breaker are not same. Its changed with respect to given Diversity factor (Ks).

So, Diversity factors (Ks) are considered for adopting offer solution and range of Transformer/Cable/Upstream circuit breaker/Feeder circuit breakers.     

Case 2: -

For this case we have cretaed 2 sysmetrical projects(All the connected loads are same range) but we have changed the Diversity factor Ks as 0.5 for second project.

Network 1 with Diversity factor Ks = 1.

Network 2 with Diversity factor Ks = 0.5.

We can see the below screenshots both projects Transformer/Cables/Upstream circuit breaker are not same. Its changed with respect to given Diversity factor (Ks).

	Network 1	Network 2
Transformer/Circuit breaker/Cables details	Project 2 with 100% loading Ks = 1	Project 1 with 50% loading Ks = 0.5

Conclusion: -

From the above analysis we came to know that diversity factors are considered during modifying of Ks.

Transformer, Cables, Circuit breakers & upstream current (Ib) changing based on diversity factors on each level of busbars/Panels.
