Predictika · Oil distribution transformers

An AI sales agent's transformer order, checked before it goes out

An AI sales agent prepares an order for oil-immersed distribution transformers: a family, a rating, a voltage, an application, a tap changer and a tank construction. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the Elsewedy Electric oil distribution transformer catalogue and returns a verdict, every reason and the figures it computed.

Scope: Elsewedy Electric oil-immersed distribution transformers (small distribution, large distribution, medium power and special transformers): rating range per family, voltage ceiling, applications, tap changer and tank construction. See everything this validator covers

This validator models orders for the oil-immersed distribution transformer families in the Elsewedy Electric catalogue it was built from, not just the scenarios shown below.

  • Families and ratings — small distribution (50 to 250 kVA), large distribution (250 to 5,000 kVA), medium power (5,000 to 15,000 kVA) and special transformers, within the catalogue range of 25 to 15,000 kVA and a highest voltage of 36 kV.
  • Applications and special types — the applications the catalogue lists for each family (for example pole-mounted only on small distribution, unit and package substations on large distribution, generation on medium power), and the special types solar, wind, variable speed drive, converter, arc furnace, traction, zigzag earthing and earthing auxiliary.
  • Tap changer and tank — an on-load tap changer on special transformers only above 500 kVA; hermetically sealed and corrugated wall tanks below 5,000 kVA; conservator and radiator tanks and galvanized tanks only where the catalogue table offers them. Winding material, insulation class, fluid and cooling are all offered on every family and are accepted as listed.

Any order for these transformers that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (the catalogue lists none, so this validator produces no price build-up or line-item quote), cast resin dry-type and power transformers, substations, losses, impedance, vector groups, test requirements and project-specific designs. Assumptions: the catalogue prints the radiator tank range back to front and shows a conservator transformer at 1,000 kVA in its own example data sheet although its table lists conservator tanks for 5,000 to 15,000 kVA, so radiators carry no rating limit here and a conservator below 5,000 kVA is sent for a person to confirm rather than blocked; medium power transformers are assumed to follow the large distribution column of the catalogue table.

The AI sales agentBuilds the transformer order from the conversation and says it is ready.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
Tank type that depends on the ratingOnly with workarounds
Hermetically sealed and corrugated wall tanks are offered below 5,000 kVA, conservator tanks higher up, and small distribution has its own shorter list; in a rules-based CPQ that is a table of option rules per family and rating band.		The family, rating and tank travel in one request and every tank rule is checked on every call.
Options that exist only on some familiesOnly with care
Galvanized tanks, on-load tap changers (special transformers only above 500 kVA) and special types each belong to some families only; each is a separate product rule to keep in step with the catalogue.		Family, tap changer, tank and special type are checked together, so a valid option on one family is flagged on the next.
Applications per familyOnly with care
Pole-mounted belongs to small distribution, unit and package substations to large distribution and generation to medium power; every family needs its own list of allowed applications.		The application is checked against the family's list on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is completed, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order for oil-immersed distribution transformers: a family, a rating, a voltage, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the Elsewedy Electric oil distribution transformer catalogue and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote 12 oil-immersed small distribution transformers of 315 kVA for a highest voltage of 11 kV, for pole-mounted use. It is ready to send. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. A rating of 315 kVA is outside the range of this family: small distribution is 50 to 250 kVA, large distribution 250 to 5,000 kVA and medium power 5,000 to 15,000 kVA. Small distribution transformers are offered with a hermetically sealed or corrugated wall tank, not with a conservator or radiators. A galvanized tank is an option on large distribution and special transformers, not on small distribution.
    6. 
      
  6. The validator returned three blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for tank type that depends on the rating, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the family to large distribution and the application to pad-mounted.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Not blocked, but held for a person.
    12. 
      
  12. The three blocking findings are cleared; one approval remains for a person: conservator tank below 5,000 kVA to confirm.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the tank to hermetically sealed.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. The earlier finding is cleared.
    18. 
      
  18. Three problems caught in one call, fixed in two passes, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
    19.
