How large should the seismic bracing be for a 200mm cable tray

This study aims to develop a simple yet efficient performance-based design optimization methodology for cable tray systems in building structures. In the paper, the drift ratio between adjacent supports i. [pdf]

Self-powered relay protection has large errors

Self-powered relay protection has large errors

Despite their benefits, self-powered relays present several challenges, particularly in relation to testing. Self-powered relays take the energy they need to operate from the current delivered to the relay by the current transformer. This arrangement has. rapidly detects and isolates faults. At the same time, they introduce high-frequency transien s and complex fault. ponent for the protection of the smart grid. While they allow reducing the cost of the protection system, they are definitely a challenge for relay test sets, that are required to provide the voltage and current signals to simulate the power system fault, but also the generated signals need to have. This paper presents an optimal protection solution using an adaptive electronic relay to enhance reliability and enable self-healing. [pdf]
