Abstract
A substation intelligence monitoring system co ntains a substation computer which is connected to a numger of field devices through an input/output subsystem . Data indicative of the devices is stored in a substation database . Advanced monitoring and diagnostics use information from this database to perform various monitoring and diagnostic functions.

Description
Optimizing the maintenance, repair, and replacement of transformers, circuit breakers, IEDs, substation batteries and battery chargers, capacitor banks, a ....etc

This paper is an overview of the sources and nature of various transient over voltages and the problems that may result in a low voltage ac distribution system. Voltage transients may be repeatable transients or random impulses and they have got remarkable effects on semiconductors, electrochemical contacts, insulation etc. Switching parallel loads on the same branch of distribution system as well as lighting are responsible for these transient overvoltages. Low voltage ac mains system should be protected from these transient overvoltages. For ....etc

Electric power transmission is the bulk movement of electrical energy from a generating site, such as a power plant, to an electrical substation. The interconnected lines which facilitate this movement are known as a transmission network. This is distinct from the local wiring between high-voltage substations and customers, which is typically referred to as electric power distribution. The combined transmission and distribution network is known as the power grid in North America, or just the grid. In the United Kingdom, the network is known ....etc

Electric power transmission is the bulk transfer of electrical energy, from generating power plants to electrical substations located near demand centers. This is distinct from the local wiring between high-voltage substations and customers, which is typically referred to as electric power distribution. Transmission lines, when interconnected with each other, become transmission networks. The combined transmission and distribution network is known as the power grid in North Ameri ....etc
