Test & Inspection for Machine Status Assessment (TIMSA)

Advanced inspection program to reduce risk of failure on MV/HV rotating machines

Within our rotating machines health monitoring offering, GE’s advanced TIMSA program is the most effective and proactive test and inspection approach for both your motors and generators. With this inspection program, we will identify any critical issues in your equipment and offer best solutions to fix them before a failure occurs. The inspection will be performed by fully trained and highly skilled field service experts, giving you the best assessment of your unit health status and the key actions to maximize its life expectancy.

Following inspections, GE can provide repairs and field services support, including [parts] replacement, to help you reduce risks and optimize your maintenance costs.
GE will carry out a series of electrical and mechanical tests with excelling safe work practices, on a periodic basis adapted to your business imperatives.

But not only can we inspect your GE and non-GE rotating machines; our team of expert field service engineers will also inspect any other peripheral control, protection or instrumentation system related to the rotating machine, that you may want to include in the outage.

We perform all essential tests below to detect abnormalities in stator winding. Indeed, all traditional methods fail in detecting stator winding problems while this represents a major cause of MV/HV rotating machine failure:

  • Internal Visual inspection or boroscopic – to get a visual expert assessment of winding and core health.
  • Recording & analysis of operating data – to measure voltage, current, temperature, vibration, etc.
  • Insulation resistance test (IR) - to verify winding to ground resistance and check it is above the minimum acceptable value.
  • Polarization index (PI) – to assess cleanliness of the winding. Permissible PI is 2.0 and above.
  • Dielectric Discharge (DD) – to diagnose aging and deterioration of stator insulation.
  • RLC measurements – To check that winding is compliant with original technical specification.
  • Step Voltage (SV) – As stated in IEEE 43 § 6.4, this test assesses the winding dryness and general condition.
  • Surge test – Conducted as per IEEE 522 standard to assess the inter-turn integrity of winding by fast rise wave comparison.
  • Partial Discharge (PD) measurement 1 - To measure the winding’s response to a specific stress level and to predict its future performance.
  • Dissipation factor (tan δ) measurement 1 – To evaluate the quality of the stator winding’s insulation.

MECHANICAL TESTS (OPTIONAL)

These extra inspections will check mechanical integrity of the rotating machine components, giving you rounded integral insight on your rotating machine health status:

  • Bearing inspection – Open inspection on bearing journal surfaces, to measure and verify clearances.
  • Vibration analysis – To identify signs of wear and tear in advance to avoid very expensive damages.
  • Bearing oil analysis – To determine the overall service conditions of a bearing system and identify issues before a failure occur

SPECIALIZED TESTS (OPTIONAL)

We will recommend other tests specific to your business conditions that you may require, such as:

  • Dissipation factor measurement
  • Offline partial discharges measurement
  • Acoustic measurement
  • CT/VT characteristics analysis
  • Stator wedge mapping
  • Resonant Surge Oscillography
  • Online harmonic component analysis
  • Etc.

OTHER EQUIPMENT

We will deploy experts to inspect any other control, protection or instrumentation equipment connected to the rotating machine, that you may want to include in the inspection, providing integral inspection service recommendations, with a global system view. These may include, among others:

  • Variable frequency drives;
  • Motor starters and motor controls;
  • Automatic voltage regulators;
  • Protection relays;
  • ATEX purging systems;
  • Heat exchangers;
  • Etc.

FINAL REPORT

Customer will receive a final report with the expert assessment of Electrification Engineering Office.

  • Minor inspections: Lowly invasive electrical tests and boroscopic inspections, without exposing unit winding, completed typically in 1-2 days, usually repeated every 1-3 years.
  • Major inspections: On top of minor inspection testing, unit end shields are opened, exposing winding for direct thorough inspection and cleaning. Extra mechanical checks are added for bearings, fans, and other rotating components. These are typically completed in 3-7 days. Usually repeated every 4-6 years.
  • Rotor out inspections: On top of major inspection tasks, the rotor is threaded out of the stator for full winding inspection and cleaning, as well as extra testing. This level of inspection is recommended ad-hoc, usually takes 7-15 days, and is performed every 10-15 years.

  • OEM backed unit health status assessment.
  • Inspection tailored to your specific unit needs;
  • Expert recommendations on best actions to maximize your asset lifetime and optimize your service expenditure;
  • Integral maintenance and repairs service

Service Program Surveys

Minimizing your maintenance costs

We will carry out non-invasive inspection of the system, while the equipment is running, and work with you to understand historic maintenance, environmental conditions, budget constraints, operational constraints, and business imperatives. Our field Service expertise will effectively cover both GE Vernova and non-GE Vernova equipment. At the end of the service program survey, Electrification will provide you a detailed report that includes all features required to have an OEM backed maintenance program of your rotating machines, adapted to your business model.

  • Identify safety critical issues - safety critical problems will be brought to your attention immediately and a resolution proposed. Electrification will provide prioritized dispatch of parts needed to resolve such issues and, if necessary, the Field Service Engineer will remain on site or return to site to supervise the solution;
  • Identify operational critical issues – reductions in performance or critical items affecting reliability will be brought to customer’s attention at the end of the service survey.

  • A maintenance plan – based on your specific business constrains and our experience with thousands of similar machines, we will suggest an OEM designed maintenance plan, to help avoid that unwelcome, unplanned outage;
  • Critical spare parts – provide a list of the [spare parts] you should consider holding;
  • Suggest details of obsolete parts that you may wish to plan to replace;
  • Upgrade packages appropriate to your equipment and circumstances.

  • Service program adapted to your business needs
  • Minimized downtime/costs relationship maintenance program
  • OEM backed recommendations
  • Direct access to all required services

With rapid technological advancements, spare parts tend to become obsolete at some point. To help reduce the impact of obsolescence on your equipment and to enable you to plan ahead, GE proactively works with suppliers to identify upcoming obsolescence at an early stage. We support you with obsolescence studies specific to your equipment. We also offer last time buy of parts when possible to help you stock up on parts that are nearing end of life or will no longer be manufactured.
