Consumers Protection and Monitoring with Microcontroller Based Device for Low-Voltage Distribution Systems

Published by Petre Lucian OGRUTAN1, Lia Elena ACIU1, Dan LOZNEANU1, Ioan ROSCA2,Transilvania University of Brasov, Romania (1), Transilvania Sud Electricity Distribution (2) Abstract. Protection devices against over-voltage and over-currents for low voltage systems are equipped with varistors and gas-discharge tubes around a fuse, having a disconnection time about 200ms. This paper proposes an intelligent protectionContinue reading “Consumers Protection and Monitoring with Microcontroller Based Device for Low-Voltage Distribution Systems”

Protection of Busbar Based on Reed Switches

Published by Mark KLETSEL1, Nariman KABDUALIYEV2, Bauyrzhan MASHRAPOV2, Alexander NEFTISSOV2,National Research Tomsk Polytechnic University (1), Pavlodar State University (2) doi:10.12915/pe.2014.01.21 Abstract. A phase comparison scheme of protection of busbar on the reed switches fixed connections near conductors extending from these busbars which does not require current transformers has been studied. The article provides an analysisContinue reading “Protection of Busbar Based on Reed Switches”

Overhead Line Fault Section Positioning System Based on Wireless Sensor Network

Published by Ai-hua Dong, Xinlin Geng, Yi Yang, Ying Su, Mengyao Li, Henan Polytechnic University Abstract.

What is Short Circuit Analysis, and Why is it Done?

Published by Carelabs (Carelabz), Website: carelabz.com A Short circuit analysis is used to determine the magnitude of short circuit current, the system is capable of producing, and compares that magnitude with the interrupting rating of the overcurrent protective devices (OCPD). Since the interrupting ratings are based by the standards, the methods used in conducting a short circuitContinue reading “What is Short Circuit Analysis, and Why is it Done?”
