Regular maintenance of relay protection devices

The maintenance activities for protection relays can be categorized into three main areas: visual inspection, functional testing, and calibration. Rare operation, critical function: Protective relays may operate only once every several. If applicable, documentation is required detailing how verified protection segments overlap to ensure there is not a gap. ABB has developed a preventive maintenance concept for the well-established SPACOM, RE500 and Relion series relays.

Four Types of Wavelength Division Multiplexing Devices

WDM systems are divided into three different wavelength patterns: normal (WDM), coarse (CWDM) and dense (DWDM). Coarse WDM provides up to 16 channels across multiple transmission windows of silica fibers.

Communication devices in the relay protection room

Let's start with brief description of seven most known and most used communication medias used in power system communications (in terms of protection and automation):.

Select and set relay protection devices

This presentation reviews the established principles and the advanced aspects of the selection and application of protective relays in the overall protection system, multifunctional numerical devices application for power distribution and industrial systems, and. Protective relays and devices have been developed over 100 years ago to provide "lastline"of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions.
