4. Updating Switch Station 5 Documentation

While working on…

While working on my second project, I found major discrepancies among the circuit design, relay type, and relay manufacturer in switch station 5 between the ETAP model, as-found photos, and the single-line drawings.

And so, my 3rd…

And so, my 3rd project emerged from this discovery, and I was tasked with correcting these inconsistencies in the single-line drawings and ETAP model in order to match what was found in the field

For example, if…

For example, if you look closely at the single-line drawing of switch station 5 on circuit 1522, we find a power meter and a 50/51 and 50 ground relay.

However, this configuration…

However, this configuration is not reflected in the field.

Instead, we see…

Instead, we see that an SEL 751 protective relay that has replaced the 50 and 51 relays as well as the power meter.

After extensive revisions…

After extensive revisions and drawing reviews with my team, I submitted a DCN form and am now waiting for an update from document controls.

Due to the…

Due to the lack of sufficient documentation, this project is a part of a larger effort to accurately document the electrical architecture and equipment to reflect what is currently out in the field.

Without the proper…

Without the proper documentation, our team cannot perform many essential tasks, such as accurately addressing technical issues, developing project scope, and identifying potential safety hazards.

In addition to…

In addition to learning about the importance of keeping accurate documentation, this project taught me the basic guidelines for redlining drawings and the extensive process of drawing review, which are some of the most fundamental skills a project engineer must know.
