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.
Weshine invented AC Resonant Test Systems are especially valuable in any application where the load is largely capacitive with low loss such as power cables, gas-insulated switch gear, capacitors, generator windings, and dry testing of insulators.
