Overhead primary meter

[MichaelZeiler]

@jalsup , please review, particularly asset group/asset types.

Also, I found a typo in your type XLS. "Comercial Service Bank" should be "Commercial Service Bank"

Updated in Asset Package

Discussed with @jalsup we should also have 3 taps. @MichaelZeiler can you submit a folder with this configuration and image?

[MikeMillerGIS]

Here is a bad quality one I found on GE spec page(No rights to use it)

[MichaelZeiler]

I've made the edits to include three taps.

About a photo for this, John gave me a geometric network for PNM, my local electric utility. Looking at the GN, I see two primary meters 10 minutes from me. During my lunch break, I'll take my Nikon and photograph them.

@MikeMillerGIS I tried to create a new folder for three phase primary meters but can't figure out how to do it in github. Clues?

I intend to make folders only for broad configurations. For example, I'll make one folder for all three phase transformers, which will include the variations for delta/wye/etc. And that will correspond to the contents of each story map.

One more thing: I will place PDFs instead of AIs in each folder, as well as JPGs in 1920x1080 size with moderate compression. In Illustrator, and I presume other vector editing software, you can specify PDFs to be editable directly in Illustrator. And this has the advantage that anyone can view them.

@MikeMillerGIS Never mind about folder creation. I googled and figured it out. Seems like I need to make a ReadMe.md file to seed a new folder and I see how adding slashes creates the needed folders

@MichaelZeiler are you using github.com to manually create folders and add files?

There's plenty of simple desktop clients that make this process a lot easier, eg https://desktop.github.com/

@jalsup Here is a photo I took yesterday of a primary meter. Are those two sets of instrument transformers on top, or what? Also are those arresters on top?

[MichaelZeiler]

It also looks like a double dead end, so we need a line end instead of a tap and I don't see any switches

Hi Mike. Good pictures. We should probably put arrows on the picture to point out all the things. I wish we could get a picture from the top. This is one Primary Meter. It has two devices per phase at the top, a current transformer on top and an potential transformer on the bottom. Each is connected to the recording meter in the cabinet at the base (your second picture) This diagram might help

[MichaelZeiler]

The primary meter.

A couple of questions: in the AG/AT list, we only have 'instrument transformer', not CT/PT transformers. Are you adding those asset types?

Also, the meter box below has three meters for each phase. Is that a meter bank (assembly) containing three meters? I think so

@MichaelZeiler slight typo in the above, Structure Point -> Structure Junction

[jalsup]

A primary meter is a single unit piece of equipment. It does contain instrument and potential transformers, but it is not necessary to model those. This should be a single point feature, the primary meter. Also, the switch is on the customer side of the primary meter, if there is one. Often there is not. So, there should be a single Tap, which has an association to the Primary meter. There would be a Three Phase Gang operated Switch below the primary meter. The switch and primary meter would be in the container.

after discussion with the team, we agreed to the following

• [ ] Remove the instrument transformer. The instrument and current transformers are all part of the unit when purchased.
• [ ] Add one Tap feature per phase. This is for editing and modeling consistency
