Condition assessment and commissoning of MV & HV cable systems
Testing provides knowledge about the state of cable insulation, joints and terminations. As a acceptance test new cable systems can be cleared. As a maintenance test this knowledge contributes to the right decisions regarding maintenance, replacement or residual assessment.
Cable diagnosis with Damped AC (DAC)
Damped AC is a proven and recognized technology for high voltage diagnostic testing with application of IEEE, IEC, CENELEC and Cigrè.
With a test frequency between 20-500 Hz similar conditions as during normal operation (50Hz) are achieved. This helps to detect weaknesses that are active during normal operation. The diagnosis can be performed on all types of cables from 6.3 to 72,5 kV. With single-sided measurement, a minimum of 15 km of cable can be tested. For extra-long cables, two-sided measurement can be used.
