FAULT INDICATOR TYPE FLA3.1

Product catalog summary

General Description:
The FLA3.1 fault indicator is designed for use in overhead lines of a network. It can be installed under live conditions using an adapter and hot stick. The device is self-sustained from a current flow of 20A and features six flashing LEDs for nighttime visibility and three red display areas for daytime visibility. It supports remote communication via a bidirectional wireless connection, allowing settings adjustments without removal from the line. The FLA3.1 can distinguish between permanent and temporary faults and is adaptable to network auto-reclosers.

DATA SHEET FAULT INDICATOR TYPE FLA3.1 for overhead lines General description The fault indicator type FLA3.1 is used in overhead lines of a network. 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 to a remote control via a bidirectional wireless connection. In this way all settings of the indicator can be adjusted at any time without removing the indicator from the powered line. The FLA3.1 stands out for the great flexibility of the adjustments that can be done. Beside 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 provides for an optimized fault indication and also allows the indication of different fault types. Permanent and temporary faults can be distinguished and indicated separately. The bidirectional connection between the remote control and the fault indicator allows to read out the present current of the monitored network with the remote control at any time. The fault indicator type FLA3.1 can be connected to the remote indication interface type RIS. This allows an easy-to-install remote indication solution for the overhead line indicators.
