Cost Effective Tools for Finding the Fault Faster
and Reducing Outage Duration
Cooper Power Systems manufactures a line of S.T.A.R. — Superior, Tough, And
Reliable — faulted circuit indicators to fit your application.
Locate Faulted Sections of Cable Systems Fast, Reliably, and Accurately
We’ve put many standard features* into the S.T.A.R.™
Faulted Circuit Indicators (FCI) for maximum reliability and
simplified application.
See Feature Availability Chart on page 2 for a listing of each
model, its application, features, available options, and other
details.
S.T.A.R. Faulted Circuit Indicators from Cooper Power
Systems meet or exceed IEEE Std 495™-1986 standard,
“Guide for Testing Faulted Circuit Indicators.”
Design features:
■■ Inrush Restraint: Feature that eliminates false tripping by
ignoring inrush currents caused by reclosing operations of
protective devices on the system. A dead time of 200 ms
will activate the inrush restraint feature.
■■ Low Pass Filter: Prevents the faulted circuit indicator
from tripping on high frequency transients like those
caused by cable capacitive discharges.
■■ Temperature Compensation Circuitry: Assures accurate
and reliable performance over the entire specified
temperature range, -40 °C to +85 °C, per IEEE Std
495™-1986 standard.
■■ High/Low Trip Rating: Allows for simplified trip rating
selection based on the primary amperage rating of the
system. For example, select low for 200 A systems, and
high for 600 A systems.
■■ Variable Trip Rating: Trip design that indicates a fault
when a significant rise in current, followed by a loss
of voltage, is detected (rather than a specific, static trip
setting). The variable trip rating applies to Pathfinder™
models, and allows for a wide range of applications, as
well as a reduction in inventories, thus, saving money.
■■ Battery Life Optimization Circuitry (BLOC™): Ensures
maximum life for the battery powering the LED display.
Used in the PATHFINDER Test Point Reset (TPR) Faulted
Circuit Indicators (FCI), the BLOC feature will shut the
LED display off after 4 hours, but retains a record of fault
occurrence in memory, which can be interrogated by use
of the manual reset/testing tool. The event will remain
in memory until the unit is either manually reset or until
normal system power is restored.
■■ Reset Restraint: Prevents the fault indicator from falsely
resetting due to feedback voltages of less than 80% of
the normal voltage measured at the test point.
■■ Current Transformer Design: Eliminates false tripping
due to adjacent cable conditions.
■■ Single Clampstick Installation: Allows for quick and
simple installation with the use of a single clampstick.
■■ FISHEYE™ Display: Provides 180° visual indication of FCI
operation. This unique orange reflective target designates a
fault and a black target designates a normal condition.
■■ Test Point Adapter Kit: For applying Test Point FCI
models on non-standard test points. Kit provides metal
contact and hex wrench, for retrofitting older-style test
points, to allow installation of the Test Point FCI (Adapter
kit sold separately).
■■ Manual Testing/Reset Tool: This simple tool allows the
user to either reset a tripped FCI or to interrogate an FCI
that is equipped to store a fault occurrence in memory,
such as the PATHFINDER TPR FCI.
■■ Universal Power Supply: For low voltage reset model,
allows power source to be at any secondary voltage (120,
208, 240, and 277 Vac). (Standard LVR model requires
120 Vac.)
