This position paper, prepared by the IEEE DEIS HVDC Cable Systems Technical Committee, illustrates a protocol recommended for measurement of space charges in full-size extruded cables during load cycle qualification tests (either prequalification cycles or type test cycles). The accounts experimental practices charge measurements thick insulation coaxial terms poling time, depolarization heating and cooling specimens, as well experience gained very recently from such kind performed framework...

The early detection of potential power transformer failures can ensure the safe operation transformers. So it is practical to develop early-fault-forecasting technology for Dissolved gas analysis (DGA) in a significant basis insulation fault diagnosis, which provides full evidence general internal hidden dangers. But because stochastic growth and small quantity time-sequence data, forecasting accurate dissolved gases content oil complicated problem until now. Least square support vector...

This brief proposes a high efficiency three-port topology with simple structure. The circuit integrates buck-boost converter and LLC resonant into one MOSFET bridge, which includes three switches, thus, voltage regulation battery management are controlled simultaneously. Also, the tank can be symmetrically powered by appropriately coordinating control sequence, switching frequency range narrowed connecting PV in series. As result, cost reduction is achievable when maintaining efficiencies....
