Research Of A Equipment Which Watch And Control The Relay Protector's Communicate Channel And Two-terminal Fault Location

It is alternative , rapidly, sensitivityand dependabilitythat the relayprotection of powersystem should generallymeet four basic demand technically, and dependabilityis particularlyimportant among them, The electric protector's mistake will cause serious danger to powersystem.There are alot offactors influencingsystem dependabilityof relayprotection,amongthem include the stability and dependability of the communication channel work betweenprotectors,andstill simpletotheresearchthat thecommunicationcoursebeforeprotectingonbothsides ofthecircuit control at present,so, it is verynecessarytostudyanddevelopsuch asuit of equipment controlled. The actual project operated personnel while operating hadalready felt too that need this equipment conscientiously. Design and study this kind ofequipment, its function , in order to gathers the data from the channel and put through one orsends the data to the channel mainly in this subject, in order to achieve to and carry on thepurpose to control and testing to this channel.
