Identification of Power Leakage and Protection of Over Voltage in Residential Buildings
International Journal of Electrical and Electronics Research, 2022 In many residential buildings the electrical wires of individual houses are laid in the same conduit pipe and some mistakes could be made in identifying similar coloured wires when they are laid in same conduit pipe. Most of the faults are caused by the neutral interconnection in the wiring system.

Research on Lightning Over-Voltage Protection for 500kV GIS Substation [PDF]
2009 Asia-Pacific Power and Energy Engineering Conference, 2009 This paper combines incoming lines with 500 kV GIS substation, considering the influence of the impulse voltage-second characteristics of insulator strings, the impulse corona of incoming lines, the impulse grounding resistance of tower and the position of lightning. ATP-EMTP simulation program is applied to analyze the lightning over-voltage of 500 kV

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Pediatric sarcomas are a heterogeneous group of tumors that contribute disproportionately to cancer mortality in children. Although congenital anomalies are among the strongest known risk factors for childhood cancer, the risk of specific sarcoma subtypes among affected individuals has not yet been thoroughly evaluated. Procedure We
