SFL-2000 is a surge type fault locator which is able to locates transmission line fault accurately. The calculation error is less than 200m.(Travelling wave type fault locator) FEATURES Highly accurate locating ・Location accuracy: ±200m ・GPS time synchronization accuracy: 160ns ・High sampling frequency : 10MHz Reliable fault detection ・DFR deviaton trigger and DFR variation trigger are available to detect a fault. Voltage elements are used for fault locating (OPTION) ・Be able to locate faults even when current surge is too small to detect. Be able to manage up to 4 terminal per one transmission line ・Complies with IEC61850 and can subscribe GOOSE message from station bus, trigger DFR and record to DFR and SER. Backup fault locating functions (OPTION) ・Even when the fault surge is very small and it cannot be detected, thエsystem is able to locate the fault point by Backup Fault Locating Functions (the Current Division Ratio Method /The Impedance Method). Clamp CT ・Easy to install. Multi channels, compact size ・Be able to connect to up to 8 circuits. ・Dimension482(W)×266(H)×300(D) mm Highly operable human machine interface ・Not only F/L server but also surge recorder is equipped with a web server.
