Core Electrical Supply
Instrument transformers
CT / PT applications
Current transformer (CT) and potential transformer (PT) interfaces for measurement and protection, selected against ratio, burden, accuracy and insulation requirements.

Instrument transformers: what the design sets.
A project-configured item: its ratings come from the approved design, not from a published product sheet.

Evidence level: project details needed. Confirm the exact model code, option, revision and controlling terms of reference (TOR) before using any fact in a compliance statement, offer or installation decision.
One link in the supply chain from utility to load.
Every piece of core electrical equipment is sized against the pieces either side of it. The ratings that matter are set by the project single-line diagram.

Options and differences
What sets the rating
Metro Power matches these against the approved drawings before sourcing.
- Voltage and fault level
The system voltage, the available fault current and the insulation level at the point of installation.
- Load and growth
The present demand, the expected growth and any motor starting or harmonic load.
- Site and standard
Indoor or outdoor, pole or pad, and the utility or client specification that governs acceptance.
Application context
Where this product fits.
Typical applications for this product family. Fit still depends on the exact service, duty, operating objective and approved configuration, so treat these as starting points rather than recommendations.

Before an offer
What Metro Power confirms before Instrument transformers is offered.
Three steps, in the order they happen: what the public record already shows, what your project must confirm, and the controlled documents that close the loop.
01Professional documentation
One product identity. Five controlled evidence gates.
This schedule shows what the public record supports and what Metro Power must still match before the product becomes a technical or commercial commitment.
