Supplies for your operation
Medium-voltage transformers
Discuss distribution and industrial transformer requirements for mining operations, production facilities, commercial developments and infrastructure projects. Send the required kVA or MVA rating and primary and secondary voltages.
High-voltage power transformers
Enquire about project-specific transformer sourcing for substations, generation and network connections. Include the connection requirements, duty, transport limits and proposed installation location.
Transformer protection relays
Digital multifunction protection options can include differential, overcurrent, earth-fault, voltage, frequency and thermal protection. Functions depend on the selected relay and configuration.
Protection retrofit
Replacing an existing relay requires a review of CT and VT inputs, auxiliary supply, tripping circuits, wiring, panel dimensions and the existing protection philosophy.
Communication & monitoring
Specify SCADA interfaces, communication protocols, event recording and time synchronisation. IEC 61850 requirements and interoperability must be confirmed for the selected device.
Engineering & commissioning scope
Ask about protection concepts, coordination, configuration, testing and operator training. The scope and availability of services in Guyana are agreed for each project.
One technical enquiry for the transformer and its protection
For a new installation, start with the single-line diagram and electrical specification. For replacement equipment, include the transformer nameplate, relay model and existing wiring drawings. We review your requirements with the relevant suppliers so that ratings, interfaces, documentation and delivery scope can be clarified before quotation.
What to include in your request
- Transformer: quantity, rated kVA/MVA, primary and secondary kV, frequency, vector group, impedance, cooling and tap-changing requirements
- Site: indoor or outdoor location, ambient conditions, altitude, available space, transport restrictions and required delivery date
- Protection: single-line diagram, CT/VT ratios and classes, auxiliary voltage, trip circuits, required functions and communication interfaces
- Project: applicable utility specifications, testing and documentation requirements, installation and commissioning scope
Attach drawings, product references or a procurement spreadsheet to your email where available.
From enquiry to project supply
- Share your requirements. Send your product list and describe the intended operating conditions.
- Review the proposed products. We clarify sourcing options and relevant technical information.
- Confirm the quotation. Confirm pricing, availability, lead times and export or delivery terms before ordering.

Frequently asked questions
Can I request a transformer and protection relay together?
Yes. Send a combined technical specification so the transformer requirements and protection interfaces can be reviewed as part of the same project enquiry.
Are all protection functions available on every relay?
No. The available functions, inputs, outputs and protocols depend on the specific model and configuration. The quotation should identify the exact equipment and options.
Can an existing transformer be fitted with a modern relay?
A retrofit may be possible after reviewing the current transformers, voltage transformers, wiring, auxiliary power, trip circuits and protection coordination.
What is needed before equipment can be commissioned?
The project requires an agreed protection design, verified settings, appropriate testing and commissioning by qualified personnel. Hardware supply alone does not establish a complete protection scheme.
