Equipment selection for BRUSH Power Generation projects

Identify the particular machine

Send a complete nameplate photograph, including the model suffix and serial number. Add the manufacturing year and your plant equipment reference when available. If several similar machines operate at the site, identify which installation the enquiry concerns.

Photograph the required component separately and show its position within the machine or panel. Clear labels, connectors and mounting points help establish the item being requested.

Where a nameplate is unreadable, include the existing equipment specification or relevant pages of the machine documentation.

Specify the requested component

A part reference is more useful when accompanied by the document title and drawing position. Include the surrounding diagram, equipment identifier and revision. For a maintenance kit, list each requested component and its quantity separately.

If only a photograph is available, explain where the item is installed and what needs replacing. A mechanical assembly may require its interface drawing; an electrical module needs its label and connection diagram.

Describing a symptom helps define the enquiry, but does not establish a replacement component by itself.

Define the generator project

Describe the prime mover, operating duty and required electrical ratings. Distinguish active power, apparent power, voltage and frequency, keeping the project units visible. Include the relevant operating cases rather than providing a single output figure without context.

Send available information on the coupling, rotation direction, supports and installation envelope. State whether the enquiry covers the electrical machine alone or also cooling, excitation and control panels.

A defined package boundary makes proposed configurations easier to compare and prevents different equipment scopes being treated as equivalent.

Prepare a condenser enquiry

Start with the grid connection point and the requirements established by the power system study. Provide voltage, frequency, reactive power requirements and site conditions. Where inertia or short-circuit contribution has been specified separately, attach the study with its units and assumptions.

Define the interfaces to starting equipment, cooling, lubrication and external control. For a retrofit, include the existing machine data and single-line diagram.

This separates the proposed equipment package from the components to be retained and helps identify the information still needed for a configuration review.

Match the compressor drive

For a MAX motor enquiry, identify the compressor, its duty and the available drive documentation. Include speed, mechanical interface and electrical supply information. If a converter is part of the installed arrangement, send its designation and the electrical diagram alongside the motor data.

For a replacement assembly, explain whether it belongs to the motor, cooling package or external control system. Adjacent equipment information can clarify the arrangement, but does not replace the requested item reference.

Keep the complete manufacturer designation, including letters and suffixes, throughout the enquiry.

Identify the PRISMIC revision

For an installed A3100, A32, A12 or A50, provide the complete device designation. A front-panel photograph should be accompanied by the board or power-module label where accessible. Include the hardware revision and the available system configuration information.

When the task involves a controller replacement, attach the panel diagram, external signal list and required outcome. Interfaces and equipment scope need to be compared before a replacement configuration can be assessed.

A newer family name alone does not establish interchangeability with a particular installed module.

Set the control package boundary

State whether the enquiry concerns a GCP device, an excitation module or a PMS project. Useful starting documents include the single-line diagram, signal list and identification of existing panels. Describe the interfaces to the site control system in the project specification.

Separate equipment that will remain in operation from items requested as part of a new package. Add available connection drawings and the equipment schedule.

This keeps a request for an individual controller distinct from a panel assembly or a plant-wide power management function when configurations and quotations are compared.

Identify an existing HGI set

For an installed HGI Welf-Air set, photograph the complete set nameplate and retain the build code. The family manual distinguishes several models, so the HGI name alone does not identify a replacement item. Include your equipment documentation where the installed version differs.

List the requested assembly, reference and quantity separately. For an engine or alternator component, identify that assembly as well as the generating set. A control enquiry benefits from a panel photograph and connection diagram.

Running hours or fault symptoms provide background, while the item identity remains the starting point.

Build a planned maintenance list

For a scheduled outage, send the approved work list and the relevant references from the equipment documentation. Give the required quantity and site need date for each line. Where the list covers several machines, separate the items by their equipment or serial references.

We review the supplied schedule and identify lines that need clarification. A table supported by drawings and photographs is useful for this purpose. Keep a revision reference when the maintenance scope changes, so the enquiry and subsequent quotation can be checked against the same component list.

Describe an equipment fault

Explain the observed problem and identify the component you want quoted. If the item has not yet been established, include available messages and equipment label photographs. Mention recent equipment or configuration changes and the documentation held by your maintenance team.

This information helps define the enquiry and determine which additional records are needed. Sourcing a replacement component is separate from establishing the cause of a fault.

The site technical team should define the approved replacement scope, which can then be included as identifiable lines in the supply enquiry.

Move from enquiry to quotation

Send the equipment identity, item list and supporting files through the request form. SpareX reviews the starting information and identifies what needs clarification. If the enquiry contains several groups, indicate the priority items and your preferred order for receiving proposals.

Retain the line references from your own schedule when answering questions. Once the requested scope is defined, each proposed item can be compared by designation and quantity.

For a large documentation set, begin with the pages covering the required assembly and the contents page of the relevant section.

Plan the delivery package

Specify the destination and the receiving restrictions at your site. For a large machine, include requirements for shipment splits, packaging and available handling equipment. A mobile installation enquiry should include the frame information and permitted transport envelope.

For component orders, describe package marking and the required accompanying document set. Give the final receiving location and distinguish transport to the destination from the installation work planned by the customer.

These details help define the requested shipping scope alongside the equipment configuration, rather than leaving delivery assumptions implicit.

Check the item schedule

Before placing an order, compare the proposal with the latest revision of your equipment list. Check machine identity, component references, quantities and the boundary of each quoted item. Keep the photographs and drawing pages used to define assemblies with several versions.

Keep project revisions clear

If the project changes during the enquiry, send the updated requirements as a clearly identified revision. The agreed list can then support receiving checks and maintenance planning.

Archived equipment documentation is useful for identifying an installed machine, while the actual scope of a new supply remains defined by the agreed item schedule.
