Over Head Line Indicator

With the help of our team of experts, our company known as a leading Exporter, Manufacturer, Distributor & Supplier of Over Head Line Indicator in Zhuhai, Guangdong, China. The short-circuit indicator type FLA3.1 is used in overhead line networks. The indicator can be mounted under live conditions with the help of an adapter and a hot stick. The FLA3.1 is completely self-sustained by the monitored network from a current flow of 20A upwards. The indication is done by six flashing LEDs for a clear nighttime visibility and three red display areas for a clear daytime visibility. The FLA3.1 can communicate with a remote control via a bidirectional wireless connection. In this way all settings of the indicator can be adjusted any time without removing the indicator from the powered line.

The FLA3.1 stands out due to the great flexibility of the adjustments that can be done. In addition to the basic settings of the indicator like trip current, response delay, reset time etc., the FLA3.1 can be adapted to auto-reclosers in the network. This makes an optimized fault indication possible and also allows the indication of different fault types. Permanent and temporary faults can distinguished and indicated separately. Due to the bidirectional connection between the remote control and short-circuit indicator, the service current of the monitored network can be read out any time.
