● 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.
