You are an AI assistant with expertise in Power Electronics component failure analysis and Variable Frequency Drives (VFDs) for Electrical Engineers.
**Objective:** Identify and list potential contributing factors to an Insulated Gate Bipolar Transistor (IGBT) module failure within a Variable Frequency Drive (VFD).

- IGBT Failure Mode Description: `{igbt_failure_mode_description}` (e.g. 'Collector-emitter short circuit' 'Gate oxide breakdown' 'Bond wire lift-off' 'Thermal runaway evidence').
- Operational Data at/before Failure (CSV structure description): `{operational_data_at_failure_csv_description}` (Describe available data columns e.g. 'Timestamp DC_Bus_Voltage Output_Current Heatsink_Temperature Motor_Load_Percent Fault_Codes').
**Task:**
Generate a textual report listing potential contributing factors to the IGBT failure. Categorize these factors and relate them to the provided information. Consider these categories:
1. **Electrical Stress Factors:**
* Overvoltage (transients DC bus overvoltage). How could data in `{operational_data_at_failure_csv_description}` indicate this?
* Overcurrent (short circuits sustained overload). How could data in `{operational_data_at_failure_csv_description}` indicate this?
* ESD or gate overstress.
2. **Thermal Stress Factors:**
* Excessive junction temperature (inadequate cooling high ambient temperature). How could data in `{operational_data_at_failure_csv_description}` (e.g. heatsink temp) suggest this?
* Thermal cycling fatigue (relevant to `{igbt_failure_mode_description}` like bond wire lift-off).
3. **Mechanical/Environmental Factors:**

5. **Component Aging/Wear-out:**
* End-of-life for the IGBT module.
For each potential factor briefly explain its relevance to the `{igbt_failure_mode_description}` and how the available `{operational_data_at_failure_csv_description}` might support or refute it.
**IMPORTANT:**

- Plant Electrical System Summary: `{plant_electrical_system_summary}` (e.g. main incomer voltage levels key distribution points presence of large non-linear loads like VFDs arc furnaces).
- List of Critical Loads and Sensitivity: `{list_of_critical_loads_and_sensitivity}` (e.g. 'CNC Machine X - sensitive to voltage sags PLCs - sensitive to transients Data Center - requires high reliability').
- Current Monitoring Limitations or Goals: `{current_monitoring_limitations}` (e.g. 'currently only monthly utility bills no real-time data' or 'goal is to identify sources of harmonic distortion affecting PLCs').
**Task:**
Generate a MARKDOWN document outlining an optimized data collection strategy. The strategy MUST address:
1. **Monitoring Locations:**
* Recommend strategic locations for installing PQ analyzers (e.g. point of common coupling PCC feeders to critical loads outputs of known harmonic sources). Justify each location based on the provided plant information.
2. **Parameters to Monitor:**
* List key PQ parameters to be continuously monitored or logged (e.g. voltage sags/swells harmonics flicker transients unbalance). Tailor this list to the `{list_of_critical_loads_and_sensitivity}` and `{current_monitoring_limitations}`.
3. **Data Logging Settings:**
* Suggest appropriate settings for data logging (e.g. sampling rates aggregation intervals event triggering thresholds). Balance data granularity with storage/analysis capabilities.
4. **Monitoring Duration and Schedule:**
* Recommend initial monitoring duration and any considerations for long-term or periodic monitoring.
5. **Recommended Type of Analyzers (General):**
* Briefly mention classes of PQ analyzers suitable (e.g. Class A Class S) based on the objectives.
**IMPORTANT:**
- The strategy should be practical and cost-effective for an industrial environment.
- Justify your recommendations clearly linking them to the specific details of the `{plant_electrical_system_summary}` and `{list_of_critical_loads_and_sensitivity}`.
- Output MUST be in well-structured MARKDOWN.
- Am besten geeignet für: Elektroingenieure, Facility Manager oder Berater, die für die Sicherstellung der Stromqualität in industriellen Umgebungen verantwortlich sind und einen strukturierten Plan für eine effektive Überwachung und Datenerfassung benötigen.
