Institutions and campuses.
Build the brief around the network.

A useful starting point

A college, university or institutional campus may have teaching spaces, laboratories, residences and common services with different operating patterns. The project engineer should turn those requirements into an electrical brief. This page describes buying questions, not named institutional clients or a guarantee of suitability for every campus.

Typical needs to define

• Provide a campus single-line diagram and the intended division of loads across buildings or transformers.
• Separate existing demand from planned laboratory, residential or other future additions.
• Explain relevant backup-source interfaces, maintenance windows and any procurement documentation requirements.

Which transformer type fits?

Distribution transformers may be considered for building supply, with power transformers where the campus network calls for them. An indoor dry-type interest can be discussed up to 3 MVA, subject to installation and electrical requirements. No particular insulation system, fire class, enclosure rating or voltage is implied by the product name.

What to send for a quote

• Building/load schedule, supply voltages and consultant specification.
• Expansion phases, existing-transformer data and required interfaces.
• Site drawings, access, quantities and requested documentation/dispatch schedule.

Also include the required rating, HV/LV voltage, phase, frequency, winding preference, quantity and delivery state/country. Mark unknown values for confirmation rather than copying assumed defaults.

Documents and project-specific confirmation

OSTL acquired BIS licences in all five major transformer categories in 2020. Request the current licence documents and the applicable product/rating scope; this is not evidence of registration or approval by a utility or procurement platform. Routine tests per IS 1180 / IS 2026 are confirmed; the applicable standard and agreed test/document schedule must be checked for the offered design.

OSTL has manufactured transformers since 2007. The corporate office is in Kolkata and the transformer manufacturing unit is in Howrah, West Bengal. Discuss your brief with the Kolkata office on +91 93310 15264 or ostltd@hotmail.com.
