Name: Overhead Line Fault Indicator Certification: We have abtained VDE,UL,CE,ROHS,ISO9000 Approal and SGS Audit Supplier in China,We guarantee quality is the first. Product description: Built-in battery and power supply from the line Detect short circuit, earth fault and line current running status Three alarming methods: local daytime turnover alarm, LED alarm in night and optional remote GPRS/GSM Main function: Automatic reset The indicator's reset time 1-48 hours(can be set online), Or the local / remote flop reset( Flop with the Led display) Power The indicator is made with the new material and special circuit designed, through limiting groove to reduce permeability and vortex energy consumption on the media, When the lines' load current exceeds 7A ,the indicator began to take power Short-circuit criterion The indicator judges the short-circuit by the standard quick-break, over setting current ,parameters be set in real-time it can suppress the inrush current and power feedback , ensure a consistent with the transformer substation. It can be set as adaptive load current over current mutation criterion , also be set as adaptive load current short circuit over current mutation criterion. Alarm function: Local daytime turnover alarm, LED alarm in night Specification battery 5.4~6.5Ah/3.6V one long-life lithium batteries Take electric power 50uA-20mA/3.6V(Corresponds to a load current 7A~600A) Static average power consumption 40uA/3.6V(RF in the state of waiting to receive parameters and command) Dynamic average power consumption 50uA/3.6V( RF send data once per 5 minutes), 60uA/3.6V ( RF send data once per minutes), Available wire diameter 0~40mm(Insulated wire, bare wire) Available load current 0~600A(Default),0~100A,0~2000A,0~40 00A Quick-break Over current Delay 0~9.99S, Stepping0.01s(Wireless and remote GPRS online can adjust the parameters) Quick-break, over current settings 0~700A(Phase sequence 0~4000A/ Zero sequence 0~70A),Stepping 1A (Wireless and remote GPRS online can adjust the parameters) Maximum earth impedance 500 © Maximum short circuit current 40KA Communication distance 30~100m(11dbm, Open area), 100~300m(20dbm , Open area) Communication mode 420~440MHZ,can be divided into 10~20 Wireless band, Each band 64-speed automatic frequency hopping, bidirectional communication Voltage Linearity Better than ±5% Current Accuracy ±1%( Rated Current 100A) or ±1A(Load current 5000 times Relative humidity 95% Operating Altitude 2000m Weight 500 g Life 10 years Maximum wind velocity 35 m/s Seismicity 0.1g Visual angle 360 °
