OVERHEAD FAULT INDICATOR

(Clip-On Fault Passage Indicator)

LOCAL INDICATION TYPE

Features

● Trip Current Self-adjustment

            The fault indicator can adjust the trip current as per different load current.

 

● Advantage Trip Criteria

            The current surge ΔI and the fault current duration time Δt is accordance with the Time inverse curve.

 

● Reference Standard

            Design, test and production are completely in accordance with IEEE495-2007.

 

● Convenient Operation

The fault indicator can be installed to the overhead line directly by using a hot-stick.

 

● Entirely Sealed Structure

            The fault indicator is sealed using epoxy resin, the whole structure can withstand aging effects for a long                      time, like high temperature, and high humidity. The outside shell is made of UV resistant material, it can                        sustain exposure to high ultraviolet environment for a long time.

 

● Eliminate Misact Phenomenon

            Eliminate the reverse feeding misact based on the difference in features of reverse feeding current and                        normal fault current.

 

● Replaceable Battery

            Three batteries are assembled in a battery container to supply power for the fault indicator, the container                    can be removed to replace the batteries.

 

● 360°visible LED flash

            Bright LED lamps are used to ensure 360° visibility.

 

● Long Life Batteries

            Industrial grade battery is used for power supply and battery monitoring. The battery life is more than 8                        years.

 

● Temporary And Permanent Fault Identification

            The temporary fault will be indicated by Blue lamps, if the fault does not correct in 7 minutes, Red lamps will                flash to indicate permanent fault.
