OverviewPortable VLF sine-wave test set VLF-SIN-62 for commissioning, diagnostic and sheath testing of medium-voltage cables. Provides VLF sine-wave output up to 44 kVrms (62 kV peak), DC testing up to ±62 kV, and optional Tan Delta and partial-discharge diagnostics for condition assessment.
Key features- True VLF sine-wave output: up to 44 kVrms / 62 kVpeak
- DC test mode up to ±62 kV for withstand and sheath testing
- Automatic frequency adjustment to match cable length and load (short and long sections supported)
- Monitored withstand and DC testing modes with breakdown detection
- Sheath testing and pinpointing capability (up to -20 kV DC with ESG NT2 step‑voltage probe)
- Optional internal Tan Delta for cable condition assessment with automatic interpretation per IEEE 400.2
- Expandable for partial discharge diagnostics when paired with PDS 62-SIN PD coupler
- 7-inch colour touchscreen and touch-friendly interface for on-site operation
- Built-in data handling: internal memory, on-unit review, USB export and MeggerBook Lite compatibility; prepared for wireless transfer
- Safety features: automatic discharge, analogue residual voltage indicator and support for external safety devices

Troubleshooting & usage notes (selected)- Unit auto-adjusts test frequency when connected cable load is high for selected voltage/frequency
- If unit will not power on: check mains cable, input range and connections
- Tan Delta functions require the Tan Delta option to be activated in system settings
- For PD measurements with PDS 62-SIN, ensure correct grounding and short/direct connections to minimise interference
