Manufacturer's Comment

PATHFINDER™ Variable Trip Current Reset (CR) faulted circuit indicators are designed to quickly and easily locate faulted sections of cable systems. These faulted circuit indicators (FCI)can be installed on pad-mounted distribution transformers, sector cabinets, switchgear and overhead bare conductors. The closed core current transformer (CT) senses the fault current and provides power to operate the FCI. The unit automatically resets back to the normal position when the continuous current exceeds the 2.0 A minimum reset value. CR FCIs provide a reliable means of fault location and isolation.

The PATHFINDER Variable Trip Current Reset FCI features a trip design that senses normal load current and indicates a fault when a significant rise in current, followed by a loss of current,is detected. Hence, there is no need to specify a particular trip rating when ordering the Variable Trip Current Reset FCI. This design ensures fast,reliable and accurate operation. Variable Trip Current Reset FCIs provide a reliable means of fault location and isolation. They also eliminate fault chasing methods that are costly and time consuming, and stressful on system components exposed to faultcurrents.

Description

S.T.A.R. Variable Trip Current Reset fault indicators consist of a sensor unit with an integral FISHEYE™ target display. The closed core CT is used for both sensing the fault current and providing power to operate the FCI. The FISHEYE display provides 180° visual indication. This unique orange reflective target designates a faulted condition and a black target designates a normal condition. The FISHEYE display alsofeatures a Lexan® cover that provides superior scratch protection for the target window. The sensor unit itself features a clamping mechanism and unique spring action CT design that allows easy snap-on connection to the live conductor with the use of a single shotgun stick.

The sensor housing is made of durable, corrosion resistant materials. The electronic components are completely encapsulated to prevent environmental damage.

The Variable Trip design eliminates the need to specify a trip rating for the FCI. The load sensing feature adjusts the FCI to normal load conditions. When a fault occurs, the unit senses the rise in system current caused by the fault,followed by the loss of system power due to operation of the protective device. Thus, the Variable Trip FCI provides a “one size fits all” FCI,reducing inventory and eliminating problems caused by misapplication of FCIs.

An inrush restraint feature eliminates false tripping and is standard on all units. The S.T.A.R. faulted circuit indicator will ignore inrush currents caused by reclosing operations of protective devices on the system.A power loss of 1 cycle (16 ms) will activate the inrush restraint feature.

A low pass filter, also a standard feature, will prevent the S.T.A.R. faulted circuit indicator from tripping on high frequency transients like those caused by capacitive discharges.

The quick response time of the S.T.A.R. current reset faulted circuit indicator provides easy coordination with current-limiting fuses and other protection devices. This unique combination of standard features makes the S.T.A.R. faulted circuit indicator extremely reliable.
