Sonic & Partial Discharge Services
Detect Electrical Discharge Before Failure Occurs
Ultrasonic and partial discharge testing to identify insulation breakdown, air leaks, and hidden system faults early.
Not all electrical failures show up as heat.
Many failures begin with small electrical discharge events inside insulation, switchgear, cable terminations, or medium voltage components. These events may not yet be visible on thermal imaging but can develop into major equipment damage.
ProgUSA provides sonic and partial discharge testing to identify these early warning signs so corrective action can be taken before catastrophic failure.
Ultrasonic detection identifies high-frequency sound created by:
- Corona discharge
- Tracking
- Arcing
- Insulation degradation
Ideal for:
- Switchgear
- Motor control centers
- Cable terminations
- Transformers
- Medium voltage systems
Deliverable: Documented findings with severity ranking and corrective recommendations.
Partial Discharge Testing
We identify internal electrical discharge activity that may indicate insulation breakdown or contamination.
Applications include:
- Medium voltage equipment
- Substations
- Cable systems
- Critical infrastructure
Partial discharge testing provides early warning before insulation failure becomes visible or catastrophic.
Compressed Air Leak Detection
Ultrasonic testing also identifies:
- Compressed air leaks
- Gas system leaks
- Steam leaks
Air leaks often represent significant energy loss.
Deliverable: Leak map with estimated energy loss and ROI projection for repair.
When to Consider Sonic or PD Testing
- Aging switchgear
- Medium voltage equipment in service 10+ years
- Unknown insulation condition
- Recurring nuisance trips
- Preventive maintenance programs
- Before major load increases
