Locate Faulted Sections of Overhead Cable
Systems Efficiently using S.T.A.R.™ Electrostatic
Reset Type Faulted Circuit Indicators
Cooper Power Systems manufactures a line of S.T.A.R. — Superior, Tough And
Reliable — faulted circuit indicators to fit your application.
S.T.A.R. Electrostatic Reset Type Faulted Circuit Indicator
Cooper Power Systems S.T.A.R.™ Electrostatic Reset (ER)
type faulted circuit indicators (FCI) can be used on bare overhead cable and unshielded insulated cable, such as tree wire.
They are powered from the voltage gradient between the line
and the ground plane. Load levels do not affect the reset circuit. The unit automatically resets to the normal position when
circuit voltage is restored.
The S.T.A.R. Electrostatic Reset type FCI is designed with
a clamping mechanism that’s “a snap” to connect to an
energized system for a wide range of cable diameters.
Installation is quick and easy, with a single clampstick.
The unique FISHEYE™ display, with a highly reflective orange
target, provides enhanced 180 degree visual indication. The
display is black under normal conditions.
To select trip rating, simply choose the “HI” trip rating for
applications close in to the substation where available fault
currents tend to be greater than 800 A, and select a “LO” trip
rating for areas further out on the system where available fault
currents tend to be less than 800 A. This approach to trip
selection means that one indicator fits all cable diameters from
0.25” through 2.0”.
With this simplified approach to rating selection:
■ Ordering is easier and faster.
■ Inventory is reduced, eliminating the need to stock multiple
designs.
■ Pre-installation load surveys are not needed.
■ FCI changeouts are not necessary as systems grow.
■ Misapplication due to trip selection errors is eliminated.
