Unsupervised Learning to Locate Weak Spots in the Medium Voltage Grid

The Medium Voltage (MV) network in the Netherlands is almost entirely composed of underground cables. The failure statistics show that the interruptions in the medium voltage have a high contribution in the mean outage time per year per customer. The interruptions in the medium voltage grid are often caused by failure of circuit components...

PEA Method Space Charge Measurement, modeling & measurement of applied pulsed-voltage in different setups for MV mini-cable

Destructive consequences of trapped space charges within HVDC coaxial cable insulation, such as accelerated aging, degradation, and breakdown, are some of the most significant challenges that manufacturers and users usually come up with. Pulsed Electro-Acoustic (PEA) method is a widely-used method for space charge detection and measurement, in...
