Dual Configuration Method for Relay Protection

Dual Configuration Method for Relay Protection

In this paper, dual setting directional over-current relays are proposed for protecting meshed distribution systems with DG. Dual setting relays are equipped with two inverse time-current characteristics whose settings will depend on the fault direction. Selective short-circuit protection can be achieved in different ways, such as: Time-graded protection Time- and current-graded protection A straightforward way of obtaining selective protection is to use time grading. 2 Department of Electrical Engineering, Faculty of Engineering, Asyut University, Asyut, Egypt. Abstract Distributed generators now is widely used in electrical power networks, in some cases it works seasonally, and some types works at special weather conditions like photo voltaic systems and wind.

What is the fiber optic pigtail fusion method

What is the fiber optic pigtail fusion method

Fusion splicing is the backbone of modern fiber optic installations—and it's the primary method used when working with fiber optic pigtails. Executive Summary: A fiber optic pigtail is one of the most commonly specified yet least understood components in structured cabling. It is usually suitable for field termination using a mechanical or fusion splicer. Fiber optic fusion splicing is on the rise and Corning's Pigtailed Splice Cassettes enable faster field splicing and easy modular management of connectorization within the housing.

Regarding Cold Joint Connection Method

Regarding Cold Joint Connection Method

Cold jointing concrete is a technique used to connect two separate concrete pours that have not fully bonded together, often due to delays or interruptions in the pouring process. As you know, concrete hardens through chemical reactions between cement aggregate, water, and air. For the completed structure to be strong and long-lasting, cold joints must be handled correctly. While often dismissed as purely aesthetic blemishes, a cold joint is, fundamentally, a failure of integration—a plane of weakness that interrupts the essential structural continuity in columns that is vital for resisting bending, shear, and axial compression. The American Concrete Institute (ACI) is a leading authority and resource worldwide for the development and distribution of consensus-based standards, technical resources, educational programs, certification programs, and proven expertise for individuals and organizations involved in concrete.
