A comparable protection relay quotation starts with protected circuit, fault and coordination study, required functions. Record the required result, site interfaces and acceptance evidence in one revision-controlled RFQ. IndustryApex engineers use these inputs to define the equipment, integration and OEM/ODM scope for your project.
Shown as a configuration reference. Availability and the equipment offered for your project are confirmed separately.
This protection relay RFQ checklist is a working procurement document. Use it to turn the requirements in the Protection relay equipment guide into a written project brief and a comparable equipment offer.
What should a quotation for protection relay include?
Complete the product-specific requirements below. Keep buyer requirements, the proposed equipment response and unresolved points in separate columns. Attach the relevant drawings, samples or site records to the same RFQ revision.
| Requirement to define | How to make the response comparable |
|---|---|
| Protected circuit | Record the actual requirement, its supporting document and any unresolved point. Request a written response against the same requirement revision. |
| Fault and coordination study | Record the actual requirement, its supporting document and any unresolved point. Request a written response against the same requirement revision. |
| Required functions | Record the actual requirement, its supporting document and any unresolved point. Request a written response against the same requirement revision. |
| CT and VT data | Record the actual requirement, its supporting document and any unresolved point. Request a written response against the same requirement revision. |
| Trip and status circuits | Record the actual requirement, its supporting document and any unresolved point. Request a written response against the same requirement revision. |
| Control supply | Record the actual requirement, its supporting document and any unresolved point. Request a written response against the same requirement revision. |
| I O and communications | Record the actual requirement, its supporting document and any unresolved point. Request a written response against the same requirement revision. |
| Time synchronization | Record the actual requirement, its supporting document and any unresolved point. Request a written response against the same requirement revision. |
| Settings ownership | Attach the current revision and mark requested changes. Ask for the approved scope, engineering responsibility and change-control record. |
| Injection trip logic test | Agree the sample or case, measurement method, record and decision owner. Ask which evidence is included in the quotation. |
How to compare protection relay quotations
Return the same completed checklist to our engineering team when reviewing a revised offer. For each requirement, record the proposed configuration, included evidence, price boundary and open question. A blank response is an unresolved item; request clarification before treating two offers as equivalent.
- Protected circuit: identify the requirement revision, the proposed response and the document that supports it.
- Fault and coordination study: identify the requirement revision, the proposed response and the document that supports it.
- Required functions: identify the requirement revision, the proposed response and the document that supports it.
Request separate scope lines for the main equipment, application-specific tooling or accessories, site connections, integration work, commissioning, training and support, where applicable. Record delivery terms, quotation validity and exclusions beside the quoted price. Keep optional items separate from items required for the stated result.
Protection relay acceptance criteria: what must be agreed?
Use the following equipment requirements to frame the acceptance discussion:
- Injection trip logic test
Have the responsible engineering personnel agree the test case and method for the exact offered equipment. Record the input or sample identification, supplied configuration, observations or measurements, agreed decision criteria, open deviations and sign-off responsibility. Separate evidence available at the factory from checks that depend on the installed site. Retain the accepted records with the equipment and document later requirement changes.
OEM/ODM protection relay: define the change boundary
- Settings ownership
Distinguish approved standard options, branding and documentation from mechanical, electrical, control or process development. Send the intended application, current drawings, target market, quantities and requested changes. IndustryApex engineers review feasibility and define the proposed supply and engineering scope. Agree design ownership where relevant, the validation responsibility and the evidence that will accept the changed configuration. A reference photograph does not define the offered configuration or grant rights to relabel the pictured brand.

Frequently asked questions
What belongs in an RFQ for protection relay?
Start with protected circuit, fault and coordination study, required functions. Complete the remaining product-specific requirements in the worksheet, and attach the relevant drawings, sample information and site records. State the destination, required result and purchase timing so our engineers can review a defined project.
How do I compare protection relay quotations on the same basis?
Use the same requirement revision for each comparison. Record the proposed configuration, included evidence, required accessories or integration, commissioning responsibilities, delivery terms and exclusions. Request a written response to unresolved requirements rather than comparing the main equipment price alone.
What belongs in the protection relay acceptance record?
Identify the approved input or sample, exact configuration, agreed method, observations or measurements, decision criteria, deviations and responsible sign-off. Agree with the responsible engineering personnel what can be checked at the factory and what depends on the installed site.
Can IndustryApex review OEM/ODM protection relay requirements?
Yes. Send the application, requested changes, drawings, target market, quantities and acceptance requirements. IndustryApex engineers review the proposed equipment and engineering scope. Feasibility, validation work, commercial terms and delivery are confirmed for the agreed project; the reference photograph does not establish branding rights.
