The Fault Indicating System (F.I.S) monitors the line 24 X 7 for fault occurrence.
The F.I.S monitors, records, and transmits the line for the following data, Load Current, Electric Field Value, Line Temperature, Ambient Temperature, Fault Current (Maximum of 1200 A), Line Status (On / Off).
The F.I.S indicates the occurrence of fault, by local indication and by SMS directly to the officials and also to the SCADA Centre.
The fault indication is reset automatically on restoration of power OR after a fixed interval of time if the power is not restored.
The F.I.S indicates when the line has been restored, by local indication (reset of fault indication), by SMS directly to the officials and also to the SCADA Centre.
The F.I.S continuously monitors the line and at fixed intervals provides the status of the line to the SCADA Centre and by SMS directly to the officials (load current).
The F.I.S has intelligent sensors to detect the in-rush current and does not indicate it as a fault.
The FPI can be installed and uninstalled (removed) online, without disrupting the power supply using a hot stick and installation tool.
All the components of the Fault Indicating System are Anti-rust, Corrosion resistant, and UV resistant, hence suitable for long time outdoor exposure, ensuring long life.
The F.I.S is self-sufficient and does not require any external source of power, it has an inbuilt solar panel which acts as its power source and it has a backup of up to 10 days even in cloudy conditions.
Specially made Lithium Iron Phosphate Batteries are used in the DTU which have a life time of up to 8 years and are maintenance free.
All communications in the Fault Indicating System are wireless, ensuring hassle free installation and maintenance free operation.
