The specification and the rules behind it, analysed in the blink of an eye
From thousands of pages to structured data
A guaranteed loss figure is not a specification, it is a price. Miss the penalty attached to it and the cost surfaces once the contract is running.

Every value traced back to the page it came from
Ratings and impedance
Every unit and panel, read against the IEC series.
Loonar pulls the distribution transformers, grid units, switchgear and auxiliary supply out of the tender and lists each tag by tag: rating, HV and LV voltages, vector group, impedance, cooling, tap changer and the IEC standard it answers to, with the bay reference and page cited alongside.
Technical deviations
Every deviation identified, ready for your decision.
Loonar rolls values up against your type-test evidence, so short-circuit withstand is one row for the whole 132/33 kV scope, not a check per unit. A report held for an 8 MVA design instead of the 10 MVA, on-load tap changers at twenty-two weeks, a loss penalty you cannot underwrite, cast resin below your smallest frame: each becomes a deviation with its items and the register behind it.

ClauseClient clauseStatusAssessment & proposed rewording
13. Performance > 13.1 Loss Penalties Losses exceeding the guaranteed figures shall be capitalised at £8,000 per kW and deducted from the contract price. Conflicting Capitalised loss penalties at this rate can exceed the margin on a single unit. Standard terms guarantee losses to IEC tolerance without a capitalisation formula. Assessed against Your_Company_GeneralTermsConditionsOfSale.pdf · p.4
8. Liability > 8.2 Network Outage Supplier shall indemnify the network operator for customer minutes lost caused by equipment failure. Conflicting Customer minutes lost is a regulatory penalty passed through as consequential loss. It is excluded under standard terms in every case. Assessed against Your_Company_GeneralTermsConditionsOfSale.pdf · p.6
9. Warranty > 9.1 Warranty Period 60 months from energisation, extended by any period out of service. Conflicting A rolling five-year warranty that pauses during outages has no defined end date. Standard warranty is 12 months from commissioning or 18 months from delivery. Assessed against Your_Company_GeneralTermsConditionsOfSale.pdf · p.4
4. Testing > 4.1 Factory Acceptance Test Full routine and selected type tests shall be witnessed with 15 working days notice. Aligned Witnessed FAT with notice is standard for transformer orders and is already reflected in the test plan template. Assessed against Your_Company_ComplianceCapability.pdf · p.5
14. Spares > 14.2 Strategic Spares Supplier shall hold one complete spare unit in stock for five years at its own cost. Needs review Holding a spare grid transformer for five years carries a significant working capital cost. It should be quoted as a separate framework line. Reword with AI
6. Delivery > 6.3 Liquidated Damages 0.5% of unit price per week of delay, capped at 10% of unit price. Needs review Applying damages per unit rather than per order is favourable, but the 10% cap remains above the 5% standard position. Assessed against Your_Company_GeneralTermsConditionsOfSale.pdf · p.5
7. Payment > 7.1 Payment Terms Net 60 days with 20% released on approved drawings. Aligned A design-stage milestone with Net 60 balance terms is within the accepted range for regulated network buyers. Assessed against Your_Company_GeneralTermsConditionsOfSale.pdf · p.2
The clause register
The tender conditions, clause by clause.
Every clause is classified, risk rated and checked against your standard positions. Losses capitalised at eight thousand pounds per kilowatt, customer minutes lost passed through as supplier liability, a five-year warranty that pauses during outages: the four clauses carrying real exposure surface above the twenty-eight already aligned.
