Design of transient traveling wave recorder for fault locating
Yanhua Liu · Dianli zidonghua shebei · 2003
The design of traveling wave recorder for fault locating is introduced.GPS(Global Position System)with high precision and on-board trigging circuit are adopted.Because of high sampling speed,large storage,high resolution but general real-time performance,12-bit A/D with direct RAM accessing and high speed CPLD of MAX7000S,which con structs data bus controller and address generator,are applied.The operating principle,device interfacing and especially the timing cooperation are discussed in detail.
