RELAY PROTECTION DATABASE

Journal of Energy - Energija, 2022
The article presents the development of a relay protection database through a series of phases.  In the planning phase of the database, problems in a typical relay protection department are examined  and the reasons why a database should be developed are determined. Subsequently, during  the phase of analysis and the specification of requirements, what

Electronic Protective Relays

Transactions of the American Institute of Electrical Engineers, 1948
Although electromagnetic protective relays are adequate for present requirements, the ever-increasing demand for higher speeds and greater accuracy and dependability seems likely to exceed the capabilities of relays now available. However, the trend toward electronic control circuits in other branches of electrical engineering, coupled with the recent ...

Pilot wire relay protection

Electrical Engineering, 1935
Recent developments in relay protective schemes, using metallic pilot channels for isolating a transmission line during fault conditions, reduce conditions, considerably the magnitude of the currents which must be handled. Schemes recently developed have many other advantages over the older pilot wire schemes being more economical to install and ...

Transmission Line Relay Protection

Transactions of the American Institute of Electrical Engineers, 1919
This paper is divided into three parts, the first part consisting of a list of relay nomenclature according to function and application, the second part being a general discussion on relay protection with special reference to an investigation of the Protective Devices Committee to obtain information on transmission line protective scheme and the third ...

Relay Protective Systems

Transactions of the American Institute of Electrical Engineers, 1912
Reviewing American practise in the use of relay protective devices for electrical generating, transmission and distributing systems, there appears to have been no material change in the construction or commercial application of this class of apparatus in a considerable period of years.

Characteristics of protective relays

Proceedings of the American Institute of Electrical Engineers, 1912
The object of this paper is to describe the general characteristics of protective relays necessary for the automatic and selective action of circuit breaking and switching devices connected to electrical distributing systems. It is not my purpose to discuss or advocate any specific type or make of relay, but rather to bring before you the necessary ...
