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.
