SUBSTATION CABLE VOLTAGE RATING BASIC INFORMATION AND TUTORIALS by ELECTRICAL ENGINEERING DESIGN AND TUTORIAL RESOURCES on Dec 8, 2012The selection of the cable voltage rating is based on the service conditions of 2.1, the electrical circuit frequency, phasing, and grounding configuration, and the steady-state and transient conductor voltages with respect to ground and other energi...



CLASSIFICATION OF CABLES USED IN SUBSTATION BASIC INFORMATION by ELECTRICAL ENGINEERING DESIGN AND TUTORIAL RESOURCES on Dec 8, 2012No single cable characteristic should be emphasized to the serious detriment of others. A balance of cable characteristics, as well as good installation, design, and construction practices, is necessary to provide a reliable cable system. Service...



BASIC ASPECT OF SUBSTATION GRID DESIGN BASIC INFORMATION AND TUTORIALS by ELECTRICAL ENGINEERING DESIGN AND TUTORIAL RESOURCES on Nov 16, 2012Conceptual analysis of a grid system usually starts with inspection of the substation layout plan, showing all major equipment and structures. To establish the basic ideas and concepts, the following points may serve as guidelines for starting a typi...



GROUNDING GRID DESIGN IN DIFFICULT CONDITIONS BASIC INFORMATION AND TUTORIALS by ELECTRICAL ENGINEERING DESIGN AND TUTORIAL RESOURCES on Nov 16, 2012In areas where the soil resistivity is rather high or the substation space is at a premium, it may not be possible to obtain a low impedance grounding system by spreading the grid electrodes over a large area, as is done in more favorable conditions.



HVDC CONVERTER STATION LOSSES BASIC INFORMATION by TRANSMISSION LINES DESIGN and ELECTRICAL ENGINEERING HUB on Nov 9, 2012As a general principle, it would be desirable to determine the efficiency of an HVDC converter station by the direct measurement of its energy losses. However, there are practical difficulties that prevent such a measurement, including the followin...



SUBSTATION SECURITY AND PROTECTION DURING EARTHQUAKE BASIC INFORMATION AND TUTORIALS by ELECTRICAL ENGINEERING DESIGN AND TUTORIAL RESOURCES on Sep 26, 2012RELATIONSHIP BETWEEN EARTHQUAKE AND SUBSTATIONTo secure and protect substation equipment from damage due to a seismic event, the relationship between earthquakes and substation components must first be understood. Earthquakes occur when there is a su...



LIGHTNING PROTECTION OF SUBSTATION DESIGN PROBLEM BASIC INFORMATION AND TUTORIALS by ELECTRICAL ENGINEERING DESIGN AND TUTORIAL RESOURCES on Sep 26, 2012Substation design involves more than installing apparatus, protective devices, and equipment. The significant monetary investment and required reliable continuous operation of the facility requires detailed attention to preventing surges (transients)...



RECOMMENDED FIRE PROTECTION MEASURES FOR SUBSTATION EQUIPMENT by ELECTRICAL ENGINEERING DESIGN AND TUTORIAL RESOURCES on Sep 26, 2012BatteriesThe hydrogen gas given off from batteries that are located in confined areas can, at certain concentrations, become an explosion hazard. Therefore, a continuously operating exhaust system should be installed when batteries are located in a r...



AUTOMATED SWITCHES USED IN POWER SYSTEM BASIC INFORMATION AND TUTORIALS by ELECTRICAL ENGINEERING DESIGN AND TUTORIAL RESOURCES on Sep 8, 2012A key part of an automated feeder switching system is the automated switch. The term “automated” in this context means the switch is designed for use on an automated or SCADA system. In order to be automated, existing switches may be retrofitted...



ELECTRIC AND MAGNETIC FIELD OF A POWER SUBSTATION BASIC INFORMATION ANF TUTORIALS by ELECTRICAL ENGINEERING DESIGN AND TUTORIAL RESOURCES on Sep 8, 2012Electric substations produce electric and magnetic fields. In a substation, the strongest fields around the perimeter fence come from the transmission and distribution lines entering and leaving the substation.The strength of fields from equipment in...
