Articles cover electrical concepts such as per unit systems, industry jargon, etc.
In this post, we calculate the full load current drawn by the load. See linked post to view how the per unit impedances were calculated.

We build substations for the following reasons: Practical Considerations for Power Substations To satisfy load growth When new communities or businesses develop in areas with limited or no existing power infrastructure, there is a strong case for constructing a nearby substation. Supplying power from distant substations is inefficient due to increased power loss as heat

Let’s understand the concept of per unit system by solving an example. In the one-line diagram below, the impedance of various components in a power system, typically derived from their nameplates, are presented. The task now is to normalize these values using a common base.

These terms were coined over a time period to identify the appropriate short circuit current magnitude that engineers could use to size the switchgears, switchboards, panelboards, and the circuit breakers.
