Post‐consumer mechanical recycling of PA66–GF composite with brominated flame‐retardant is assessed using accelerated thermal ageing to reproduce long‐term thermo‐oxidative degradation typical of electrical devices. Property retention is quantified across virgin, aged, recycled, and diluted recycled states through mechanical testing, microscopy, DSC ...

Busbar Fault Direction Identification Using Sequences of Displacement Vectors
In this paper, a novel busbar fault direction identification scheme is presented. The proposed scheme is based on sequences of displacement vectors. The proposed algorithm is fast and simple enough to be embedded in a differential relay to assist the percentage‐restraint differential algorithm.

Superconducting fault current limiter application in a power-dense marine electrical system [PDF]
Power-dense, low-voltage marine electrical systems have the potential for extremely high fault currents. Superconducting fault current limiters (SFCLs) have been of interest for many years and offer an effective method for reducing fault currents.
