TRANSFORMER APPLICATION

Transformers for Industrial Plants

Select a transformer around the actual factory task: a new supply, added capacity or a replacement within existing interfaces. Share the load and site information first so the quotation can distinguish confirmed requirements from design questions.

Start with your project task

New plant electrical supply

Establish the duty and installation boundaries before requesting a fixed configuration.

Send these inputs
Utility supply details, load schedule, major motor/process loads, planned operating profile and site arrangement.
Review and coordination
Review the proposed transformer duty and interfaces against the supplied design. Have the project designer confirm system and protection assumptions.
Expected output
A proposed product range, configuration questions and the data needed for a technical quotation.
Discuss This Task

Capacity expansion

Added machinery may change the load profile and the way the existing distribution system operates.

Send these inputs
Existing transformer nameplates, measured demand where available, added-load schedule, single-line diagram and space constraints.
Review and coordination
Identify questions about loading, impedance, parallel operation and upstream/downstream interfaces; refer system decisions to the responsible designer.
Expected output
A comparison of replacement or additional-unit options subject to confirmed system requirements.
Discuss This Task

Replace an existing transformer

A matching capacity alone does not establish mechanical or electrical interchangeability.

Send these inputs
Clear nameplate and terminal photos, existing drawing, measured access and foundation dimensions, cable/busduct layout and outage constraints.
Review and coordination
Check the offered electrical rating and physical interfaces against existing equipment records. Identify measurements that require site verification.
Expected output
An interface checklist and a configuration-specific quotation/drawing scope after the missing dimensions are resolved.
Discuss This Task

Conditions that affect configuration

Motor starting and process load

The load profile can affect the transformer duty to be reviewed; capacity alone is not the complete specification.

Information to provide: Major loads, starting methods, operating cycle and any available harmonic or demand study.

Dust, heat and maintenance access

Enclosure, ventilation and maintenance clearances must suit the actual installation.

Information to provide: Ambient design conditions, contamination exposure, room ventilation and access drawings.

Explore suitable product options

Documents by project stage

Technical quotation

Agree the offered configuration, assumptions, exclusions and document list against your specification. Availability and acceptance criteria are confirmed in the quotation.

Stage: quotation

Design approval

Confirm the applicable general arrangement and terminal interfaces after the configuration and scope are agreed. Do not use a generic drawing for construction.

Stage: design approval

Inspection and handover

Agree required routine test records, marking, manuals and shipping documents before ordering. Project-specific witness tests need a separate agreed scope.

Stage: delivery

Scope and coordination

Transformer supply is one part of the electrical installation. The project designer and relevant approval authority remain responsible for the overall power-system design, protection coordination, civil works and installation acceptance. Site services, switchgear, backup equipment and project-specific tests are included only when expressly agreed in the quotation.

Questions before requesting a quotation

Can we replace a unit using only its kVA rating?

No. Provide the voltage ratio, frequency, vector group, impedance and interface details from the existing records. Dimensions and terminals also need to be checked.

Do you design the complete factory power system?

This page concerns transformer supply coordination. System studies, protection settings, civil design and installation services are outside the scope unless separately agreed.

Send your project requirements

Share the voltage, capacity, installation conditions and project specification. A document link is optional.
