A Surge Wave Generator is a high-voltage testing device used for cable fault location. It generates controlled high-energy surge pulses to pinpoint faults in underground power cables.
How it works:
- The SWG applies a high-voltage pulse to the faulty cable.
- If a fault exists, the pulse creates a flashover discharge at the defect location.
- The resulting acoustic and electromagnetic signals help technicians accurately locate the fault.
Key Features:
- High surge energy (up to 3500 J) for effective fault pinpointing.
- Variable voltage settings (2–32 kV) for different cable types.
- Integration with reflectometers for pre-location and precise fault detection.
Applications:
- Power cable fault detection in underground networks.
- Pinpointing high-resistance faults that standard methods may miss.
- Pre-location and final fault confirmation in cable diagnostics.
For example, the HVC-G is a modular surge wave generator designed for fault location and works alongside TDR reflectometers
