PCS-997S Fault Line Locator
  • PCS-997S line fault locator is based on traveling wave fault location method and used for fault location of high voltage AC transmission lines. PCS-997S samples the current traveling wave signal of the fault line, exchanges information with the device on the other side of the line through Ethernet or dedicated fiber. The sampling rate of traveling wave is 2MHz, which enables a high fault location resolution of 75m. PCS-997S supports both single-ended and double-ended traveling wave fault location methods, and the typical fault location accuracy is better than 300m. PCS-997S can monitor four transmission lines with optional analog input modules (1A/5A).
