NETWORK_EQUIPMENTDETAIL

NETWORK_EQUIPMENTDETAIL Provides details on equipment that may have outages or ratings. A single piece of equipment may have multiple records if its details change. A line will typically have at least two valid records at a time, once for each end of the line.

Column Schema

ELEMENTID

Equipment element id

SQL Type: NUMBER(15,0) Polars Type: pl.Int64

This column is mandatory, and a primary key.

Examples: 3, 3111

EQUIPMENTID

A unique identifier for this type of equipment at this substation

SQL Type: VARCHAR(30) Polars Type: str

This column is mandatory, and a primary key.

Examples:

  • 1
  • 110KV_714

EQUIPMENTTYPE

The type of equipment. Valid values are: LINE = Line TRANS = Transformer CB = Circuit breaker ISOL = Isolator CAP = Capacitor REAC = Reactor UNIT = Unit

SQL Type: VARCHAR(10) Polars Type: pl.Categorical

This column is mandatory, and a primary key.

Examples:

SQL Type: VARCHAR(20) Polars Type: str

This column is not mandatory.

Examples:

  • 6.6
  • 11
  • 138.6_11.6

Code Examples

Polars

Casting is enums, categoricals etc is not essential, but may speed up parsing. Swapping int for pl.UInt16, pl.Int32 would also speed up parsing. However some of the datatypes are inferred, so they may be wrong.

This code deduplicates for you. Deduplication is normally only required across multiple months.

This code assumes that all columns are present, which may not be true for older files.

Availability

Visibility: Public

This table is in the public monthly MMSDM archive.

I have collated the list of all those files into one place, in this CSV metadata file. (Columns year, month, url, compressed_size in bytes).

The earliest available data is month 8 of 2024. The most recent available data is month 9 of 2026.

Every month in between has a file. (No gaps.)

Data Size

Each year of data is approximately 9 MB when zipped, 86 MB as unzipped CSV.

Deduplication and PDR Loader Configuration

The primary keys are:

The transaction type is "INSERT-UPDATE", which means that you will likely see duplicate data with different values.

You should deduplicate by sorting based on LASTCHANGED, within each group of primary keys.

PDR Loader configuration is:

Report Name Report Subtype Version
NETWORK EQUIPMENTDETAIL 1
NETWORK EQUIPMENTDETAIL 2

This means that the CSV files start with metadata columns:

I,NETWORK,EQUIPMENTDETAIL,1,...
D,NETWORK,EQUIPMENTDETAIL,1,...

or

I,NETWORK,EQUIPMENTDETAIL,2,...
D,NETWORK,EQUIPMENTDETAIL,2,...

ROW_FILTER_TYPE is LASTCHANGED
