Stator winding
Insulation resistance and polarization index, winding resistance, capacitance / dissipation factor and partial discharge assessment, as applicable to the diagnostic objective.
Service · Electrical testing
Generator Electrical Testing — RSO, ELCID, PD, Hipot
Stator and rotor electrical diagnostics with a test programme defined by the machine, history and objective. Insulation, RSO, low-flux, partial discharge and applied-voltage testing are selected for the agreed scope and procedure. Planned field and workshop service.
Tests we run
4 critical electrical tests for industrial generators
Diagnostics that anticipate failure months in advance. Calibrated equipment, certified engineers, signed protocols under international standards.
Procedure defined by scope
RSO Test
Repetitive Surge Oscillograph
Diagnose inter-turn shorts in rotor field windings. Results are assessed with machine history and the agreed procedure.
Procedure defined by scope
ELCID Test
Electromagnetic Core Imperfection Detection
Diagnose stator magnetic core. Detects laminar shorts before rewind — prioritizes repair vs core replacement.
IEEE 1434
Partial Discharge
Offline + online PD measurement
Predictive insulation diagnosis on high-voltage generators. Results support condition assessment; they do not predict a guaranteed failure date.
IEEE 95-2002
Hipot AC/DC
High Voltage Test — stepped curve
Dielectric validation of insulation post-rewind and pre-commissioning. Test levels and suitability require a machine-specific assessment.
Each test executes with calibrated equipment traceable to national standards under ISO 9001:2015. Signed protocol delivered for operational release or regulatory audit.

The test programme is selected after reviewing nameplate information, history, symptoms and previous results. It is not an automatic package for every generator.
Rotor winding
Insulation and winding resistance, impedance and RSO when appropriate to the machine configuration and the question being investigated.
Offline and online tests require different arrangements. Applied-voltage testing is only included where justified by the assessment and an agreed procedure. The report documents test conditions, results, limitations and recommended next steps.
Planning questions
How far in advance should I request the service?
Contact us during outage planning, before finalizing the schedule. Lead time is confirmed after reviewing technical information, scope, access, specialists, equipment and logistics. There is no single lead time for every machine.
Does an enquiry reserve an inspection date?
No. An enquiry starts the assessment. Mobilization is scheduled once scope, commercial conditions, availability and required site preparation are confirmed.
Can several tests be coordinated during one outage?
Yes, subject to feasibility and availability. We define the sequence and work interfaces; combining services does not mean they can all run simultaneously.
PLANNED INSPECTIONS
Contact us before you finalize the outage
This is a planned specialist service. Contact TEMISA as early as possible so we can review the machine, define scope and coordinate equipment, personnel and logistics. An enquiry does not reserve a date.
- 01
Request early
Share manufacturer, model, rating, site, inspection objective and proposed outage dates before finalizing the plant schedule.
- 02
Review feasibility
We review drawings, photographs, history and access. We identify missing information and the specialists and equipment required.
- 03
Agree scope and dates
The proposal defines tests, deliverables, exclusions, responsibilities and schedule. Mobilization requires confirmed availability and commercial conditions.
- 04
Prepare and execute
The site provides agreed access and equipment release. The team verifies readiness, coordinates other work and records the actual test coverage.
- 05
Report and plan next steps
Findings, limitations and recommendations are delivered on the agreed timetable. Further tests or repairs are scoped separately.
What determines lead time?
Machine geometry, completeness of technical information, specialist and equipment availability, site preparation, location and travel or customs requirements. The proposal separates preparation, testing, reassembly and reporting; test duration is not total outage duration.
