Research on Decentralized System of Fault Wave Recording and Operation Monitoring

The decentralized system of fault wave recording and operation monitoring can be widely used in transformer and power distribution substations with voltages ranging from 380 V to 220 kV in various enterprises. It is a system of digital treatment and display of fault wave, consisted of mini recorders for fault waves in decentralized installation, digital communication network by RS485 and industrial controller as core.
