Predictika · Distribution transformer orders

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

An AI sales agent prepares an order for Prolec GE distribution transformers: single-phase pole-mount, single-phase pad-mount or three-phase pad-mount, with rating, quantity, primary and secondary voltage, impulse level, options and site altitude, and the total kVA the order states. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the brochure's published ranges and options and returns a verdict, every reason and the figures it computed.

Scope: Prolec GE single-phase pole-mount, single-phase pad-mount and three-phase pad-mount distribution transformers: ratings, voltages, impulse levels, options, altitude and stated total kVA. See everything this validator covers

This validator models the distribution transformer ranges in Prolec GE's public brochure, not just the scenarios shown below.

  • Ratings — the standard kVA lists for single-phase units (10 to 167 kVA) and three-phase pad-mount units (45 to 2,500 kVA); other ratings go to a sales representative, and three-phase pad-mount ratings above 5,000 kVA are blocked.
  • Primary voltage and impulse level — three-phase pad-mount primaries are checked against the standard voltage table (delta or wye, and grounded wye) with its impulse levels; dead-front primaries are limited to 45 to 150 kV and live-front to 45 to 200 kV; single-phase units to 60 to 150 kV; primaries above 34,500 V are blocked.
  • Secondary voltage — 120/240, 240/480 or 277 V on single-phase units and 208Y/120 or 480Y/277 V on three-phase pad-mount units; a secondary for the wrong number of phases is blocked.
  • Options — a dual-voltage primary cannot be combined with an external tap changer on single-phase units; the self-protected (CSP) design is a pole-mount option; options the brochure lists for other types only (switch, low-voltage breaker, seismic zones, live front, 55 C rise, copper windings) go to a person for approval.
  • Altitude — three-phase pad-mount units are designed up to 3,000 m; higher sites are blocked.
  • Stated total kVA — the total on the order is compared with quantity times rating.

Any distribution transformer order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (the brochure lists none, so this validator produces no price build-up or line-item quote), power, substation, wind and solar transformers, network transformers and voltage regulators, and custom designs.

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
A standard voltage table that sets the impulse levelOnly with workarounds
A lookup from primary voltage and connection to the standard impulse level has to be built as a table and a price-style rule, and re-checked whenever the brochure is reprinted.		The voltage, connection and impulse level arrive together and are checked on every call.
Different impulse-level ranges for dead-front, live-front and single-phase unitsOnly with care
Three separate range rules, each conditional on type and front; easy to miss one when a type is added.		Each range is checked with every other rule in the same call.
A dual-voltage primary that cannot be combined with a tap changer on single-phase unitsOnly with care
An exclusion rule between two options, restricted to certain types; it works, but each such exclusion is another rule to write and test.		The exclusion is checked against the unit type on every call, whatever order the choices were made in.
Options listed for one transformer type but not for anotherOnly with care
A compatibility matrix of options against types; every new option or type extends the matrix.		Options are checked against the unit type together, and anything outside the brochure goes to a person for approval.
A stated total kVA that must equal quantity times ratingOnly with workarounds
A stated figure is a free-entry field; a rule can compare it with a computed total, but someone has to write and maintain that comparison.		The stated total travels with the order and is compared with the computed total on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the quote 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.

  

  

    
What this validator catches: findings from its test cases
Click to expand
    
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.

    
1The quote states a total of 500 kVA, but the transformers on it total 1,000 kVA.
2The quote states a total of 550 kVA, but the transformers on it total 500 kVA.
3A primary voltage of 46,000 V is above the 34,500 V that this range goes up to.

5A dual-voltage primary is not available with an external tap changer on single-phase units.
6The self-protected (CSP) design is a pole-mount option; it is not offered on pad-mount transformers.
7The primary impulse level of 45 kV is outside the 60 to 150 kV range offered on single-phase units.
8The primary impulse level of 200 kV is outside the 60 to 150 kV range offered on single-phase units.
9The primary impulse level of 200 kV is outside the 45 to 150 kV range offered with a dead-front primary.
10The standard primary impulse level for this voltage is 150 kV; 200 kV is not in the standard table, so confirm it with a sales representative.
11The primary impulse level of 250 kV is outside the 45 to 200 kV range offered with a live-front primary.
12The standard primary impulse level for this voltage is 95 kV; 250 kV is not in the standard table, so confirm it with a sales representative.
13The primary impulse level of 30 kV is outside the 45 to 150 kV range offered with a dead-front primary.
14The standard primary impulse level for this voltage is 45 kV; 30 kV is not in the standard table, so confirm it with a sales representative.
15An altitude of 3,500 m is above the 3,000 m up to which the three-phase pad-mount transformer is designed.
16A rating of 5,000 kVA is not on the standard list for this transformer type; Prolec asks that such ratings go to a sales representative.
17A rating of 6,000 kVA is above the 5,000 kVA (ONAN) that the three-phase pad-mount range goes up to.
18A rating of 6,000 kVA is not on the standard list for this transformer type; Prolec asks that such ratings go to a sales representative.
19A rating of 400 kVA is not on the standard list for this transformer type; Prolec asks that such ratings go to a sales representative.
20A rating of 200 kVA is not on the standard list for this transformer type; Prolec asks that such ratings go to a sales representative.
21A primary voltage of 14,000 V with this connection is not in the standard table for three-phase pad-mount units; confirm it with a sales representative.
22The standard primary impulse level for this voltage is 95 kV; 110 kV is not in the standard table, so confirm it with a sales representative.
23The 277 V secondary is listed for pole-mount units; the pad-mount single-phase units list 120/240 and 240/480 V.
24A live-front primary is listed for three-phase pad-mount units; for this type confirm availability with a sales representative.
25A low-voltage circuit breaker is not listed among the options of the single-phase pad-mount unit; confirm it with a sales representative.
26A two-position or load-break switch is not listed among the options of the pole-mount unit; confirm it with a sales representative.
27Seismic zone designs are listed for three-phase pad-mount units; for this type confirm availability with a sales representative.
28The 55 C and 55/65 C temperature rises are listed for three-phase units; the single-phase brochure lists no temperature-rise option.
29Copper windings are listed as an option for three-phase units; the single-phase brochure lists none, so confirm with a sales representative.
30The quote states a total of 900 kVA, but the transformers on it total 800 kVA.
31The primary impulse level of 250 kV is outside the 45 to 150 kV range offered with a dead-front primary.

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 Prolec GE distribution transformers: single-phase pole-mount, single-phase pad-mount or three-phase pad-mount. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the brochure's published ranges and options 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 6 three-phase pad-mount distribution transformers of 1500 kVA each, primary 13,800 V with a 95 kV impulse level. Options: seismic zone design. The rest of the request is on screen. The order states a total of 7,500 kVA.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with two findings, all in one answer. The quote states a total of 7,500 kVA, but the transformers on it total 9,000 kVA. The secondary voltage on the quote does not match the number of phases of the transformer type; single-phase units have 120/240, 240/480 or 277 V secondaries and three-phase pad-mount units have 208Y/120 or 480Y/277 V.
    6. 
      
  6. The validator returned two 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 and against the stated total.
    7. 
      
  7. What this shows: for a dual-voltage primary that cannot be combined with a tap changer on single-phase units, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the secondary voltage to 480Y/277 V and the stated total to 9,000.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. Both earlier findings are cleared, and the validator's figure matches the quote.
    13. 
      
  13. Two problems caught in one call, fixed in one pass, 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.
    14.
