Mobile Test Equipment

Type of Source: Variable Frequency Resonant Test Unit.

Ready-to-go test trailer for on-site commissioning tests on HV underground and submarine cables and gas insulated substations. Capacity to energize cables from 45 kV to 400 kV rated voltage and maximum lengths up to 12 km ( Depending on the capacitance of the cable.). Possibility of testing higher voltage cables and longer lengths using various resonant systems through collaborative agreements with other entities.

Ratings:   260 kV, 80 A, 20-300 Hz.
