Coordinate the site and factory records
Give the ratings, winding arrangement and tap designation from the manufacturer. Identify any factory test record or previous site report available for comparison. Where the purchase order covers more than one transformer, associate each document with the individual unit.
Select the measurements for quotation
List the checks called for by the site acceptance plan, for example turns ratio, winding resistance or insulation resistance. Include the requested tap positions and any witnessing requirement. A portable insulation resistance tester from your maintenance kit can be quoted separately for calibration.
Matching the report to the unit on site
Several transformers on a project can share a rating and supplier. Match the manufacturer's serial number and the plant tag to the single-line drawing before issuing a test request. Record the winding designation and tap position associated with existing factory measurements, particularly if the site wants to compare those figures with new observations.
At handover, identify which test sheets require witness signatures and which are reference records supplied by the manufacturer. If a test is deferred, record the open item and its responsible owner separately from the signed results. The plant's authorised team controls release of the equipment.
Agree the handover between contractor and owner
For a new section of a plant at IMT Kharkhoda, identify who controls site access, isolation and the commissioning release. If other transformers on the order are installed in another state, record each site’s readiness date before scheduling travel.
Servo transformer measurements
A servo transformer enquiry should identify the complete regulator assembly, its input and output arrangement and the quantities needing results. Voltage indication, response to a changed supply and regulation under load are separate observations. Give the factory's operating conditions and access plan. RTS can review the intended commissioning or measurement work, with individual meters listed separately; the assembly should not receive a blanket calibration description without a defined measurand.
Welding transformer and associated indicators
For a welding transformer, distinguish the power unit from the current and voltage indications used by the operator. Provide the process type, output mode, load conditions and the selected readings that your procedure controls. An assessment may need the installed output circuit and its reference method reviewed. Include the duty arrangement and responsible electrical contact; a meter comparison alone should not be presented as certification of the whole welding process.
