App Concept
GroundFaultAnalyzer Pro
A diagnostic tool that captures and analyzes high-frequency transients and DC bus voltage on VFD-fed systems to pinpoint the source of unexpected ground fault current. Provides real-time waveform analysis and guided troubleshooting steps, saving hours of manual probing and guesswork.
Key Features
- Simultaneous voltage and current waveform capture at multiple points
- VFD DC bus voltage monitoring and transient detection
- Machine-learning based fault source identification (motor cable vs. DC bus)
- Step-by-step guided diagnostics with report generation
Target Users: Electricians and electrical engineers troubleshooting ground faults in industrial settings with VFDs and resistance-grounded transformers
Revenue Model: $299/device (hardware) plus $29/mo software subscription for updates and advanced analytics
