Description
Overview
GAOTek Frequency Conversion Series Resonance Test Device AC insulation testing provides the ideal solution to testing these lighter cables. AC insulation testing better simulates the day-to-day stresses undergone by power systems, including frequencies like 50/60 Hz, without causing the insulation breakdown common in DC testing. Additionally, AC testing won’t affect XLPE cables when used for over-potential testing, to an agreed acceptable insulation resistance value.
Features
- Tests resonance in electrical systems
- Accurate frequency conversion capability
- Multiple frequency ranges supported
- User-friendly interface
- Reliable and safe operation
- Robust construction for durability
