Electricity loss and illegal-use inspection

Losses show on the transformer, not on the meter; inspection teams can visit only so many meters, and each finding needs photos, a report, and an accrual worked out by the regulation's method.

With the systemMeters ranked for a visit, field photos read, the file assembled, period and consumption computed; the specialist signs.

Meter-change report (EK-6) · meter M-4471

The meter was removed for laboratory examination and a sealed meter was fitted in its place; the terminal-cover seal was found broken, and the meter was photographed with its serial number visible.

1. The work

Today

  1. SelectInspection teams are sent from tip-offs, high-loss feeders, and lists of meters whose consumption dropped; the list is long and the teams are few.
  2. ReadAfter a visit, a specialist opens the team's photos one by one to check the meter serial, the index, the seals, and the wiring against the illegal-use report (tutanak).
  3. AssembleConsumption history, earlier meter work, earlier findings, and the laboratory report are pulled by hand from billing, the meter-data system, and work orders.
  4. ComputeThe period and the consumption are worked out in a spreadsheet by the regulation's method for the case on the report, and a slip shows up only when the consumer objects.
  5. DecideThe loss and illegal-use specialist checks and signs the accrual; the invoice must reach the consumer within three business days of detection.

With the system

  1. SelectEach transformer's energy balance is computed in code, and the machine-learning model ranks the meters below it for a visit, each with its reasons; your planners choose the routes.Model
  2. ReadThe vision-language model reads the field team's photos: the meter serial and index, the seal numbers and their state, and any visible intervention in the wiring, and marks where a photo and the report differ.SLM
  3. AssembleThe agent assembles the file read-only: the report, the laboratory report, the photos as read, the consumption history, the last recorded meter work, and any earlier findings.Agentic AI
  4. ComputeYour written checks, run as code, compute the period and the consumption only where the regulation writes the method for that case; any other case goes to the specialist uncomputed.Your rule
  5. DecideThe loss and illegal-use specialist checks the file against the photos and the report and decides and signs the accrual, as before, under the regulation's procedure.Person decides

What lands on the desk

The specialist opens one file: why the meter was visited, what each photo shows and where it differs from the report, the laboratory result, the meter's history, and the period and consumption computed by the regulation's own method. Nothing is billed or cut by the system.

How the agent's work is arrangedFixed workflow

Fixed workflow

Every finding needs the same file in the same order (report, laboratory report, photos, history, earlier work), so a fixed sequence is enough and easy to audit.

How the models are trained and tested

Your expert writes the test first. A step the test does not need is skipped, and we say why.

Show the training steps

Inspection-priority model (machine learning)

  1. Target

    Illegal use confirmed by a signed report and not overturned on objection, per meter and time window.

  2. Data

    12–36 months of smart-meter readings and events, transformer balances, network data, and past inspections with their outcomes.

  3. Method choice

    Champion vs. challenger: a gradient-boosted model against a logistic baseline and the rules you use today; no method presumed better.

  4. Validation

    Out-of-time validation, calibration by rank band, and stability across regions and seasons; documentation for your own review.

  5. Monitoring

    New meter types, network changes, and seasons trigger a re-check; a set of visits chosen at random measures what the list misses.

Vision-language model (VLM) for field photos

  1. Test set

    300–600 field photos labeled by your senior inspectors before training: meter serial, index, seal number and state, visible intervention.

  2. Dataset

    Past field photos with their reports and laboratory results; people in the photos cropped or masked.

  3. Continued pre-training (CPT)Skipped

    Skipped: reading meters and seals needs no field language the base model lacks.

  4. Supervised fine-tuning (SFT)

    On photo and field pairs from your own meter types and seals.

  5. Reinforcement learning (RL)Skipped

    Skipped: reading fields is taught by fine-tuning, and no further reward is needed.

Where the agentic system stops

The field team writes and signs the report at the site; the loss and illegal-use specialist decides and signs the accrual under the regulation's procedure, and your planners choose which meters are visited.

Show its tools, limits, and record
Tools and access
Reads the report and photos from the field app, billing, the meter-data system, work orders, and earlier accrual records, read-only; writes only the inspection file.
May not
Decide that use was illegal, sign or change a report, issue an invoice or a payment notice, cut or reconnect supply, file a criminal complaint, contact the consumer, or grant itself any access.
Who decides and the written limit
Loss and illegal-use specialistThe field team writes and signs the report at the site; the loss and illegal-use specialist decides and signs the accrual under the regulation's procedure, and your planners choose which meters are visited. The system never decides that use was illegal, never cuts or reconnects supply, never issues an invoice, and never files a criminal complaint.
Stops when
A photo it cannot read with confidence, a photo that differs from the report, a missing laboratory report where one is required, or a case without a written method: the file goes to the specialist, marked.
Record
Every record and photo read, the model and rule versions, each computation and the article behind it, and who signed the accrual.

How agentic systems stay inside limits

3. Value and conditions

Where the time goes, and what your institution will measure.

Where the value comes from

  1. More confirmed findings per inspection visit.
  2. Accrual files complete and computed by the written method, so fewer objections upheld.
  3. Specialist time per file.

What your institution measures

  • Confirmed findings per inspection visit
  • Non-technical loss per transformer
  • Accruals overturned on objection
  • Time from detection to invoice
  • Specialist time per file

Measured in the Decision Blueprint

Today's confirmed findings per visit and accruals overturned on objection, from your inspection and objection records, set the baseline; your institution sets the target.

Conditions

The rules, the data, and the known error, with its guard.

  • The regulation names the cases of illegal use and the detection steps; where a meter intervention is suspected, the meter is removed and the illegal-use report (EK-5) follows only once a laboratory report confirms it (Elektrik Piyasası Tüketici Hizmetleri Yönetmeliği arts. 42 and 43). The field team and your unit do every step the regulation names.
  • Period and consumption follow the regulation's methods and limits for each case (arts. 44 and 45); the code applies only a method written there. The invoice goes out within three business days of detection, and the consumer may object within six months (art. 47).
  • Findings are photographed and, for the cases in art. 42/1 (a) to (c), also recorded on video (art. 43); the model reads photos only, and the video stays with the team and the unit.
  • The ranking learns from past inspections, which were not chosen at random, so a set of visits chosen at random measures what it misses. People in photos are cropped or masked, and meter data stay on your servers.
