    Remote FISHEYE™ Display

    The Cooper Power Systems remoteFISHEYE display provides 180°visual indication of FCI operation. This unique orange reflective target fits a standard remote indicator window that exists in many padmount transformer specifications.

    Small Remote Display

    The Cooper Power Systems’ TPR FCI is also available with a small remote flip-target display. This display can be easily retrofitted for padmount cabinets with a single hole installation.Refer to S320-40-1 for installation details.

  • manufacturer's comment: Cooper Power Systems S.T.A.R.™Test Point Reset (TPR) faulted circuit indicators are designed to quickly and easily locate faulted sections of underground cable systems. These faulted circuit indicators (FCIs) can be used on both 200 A separable connectors and 600 A terminators with a voltage test point. The removable sleeve allows for use on major manufacturers’ loadbreak elbows. S.T.A.R.TPR FCIs feature a stored energy design that utilizes the capacitively coupled voltage present at the elbow test point. This design ensures fast,reliable and accurate operation. All FCI units are shipped to the customer in the tripped position. The magnetically latched target will not change status as a result of mechanical shock or vibration. After the unit is installed,the energized system will reset the flag from the tripped position to the normal position.

  • manufacturer's comment:

    Cooper Power Systems S.T.A.R.™PATHFINDER™ Variable Trip Test Point faulted circuit indicators (FCI) are designed to quickly and easily locate faulted sections of underground cable systems. These FCIs can be used on both 200 A separable connectors and 600 A terminators with a voltage test point. The removable sleeve allows for use on major manufacturers’ loadbreak elbows.

    The PATHFINDER Variable Trip Test Point 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 voltage,is detected. Hence, there is no need to specify a particular trip rating when ordering the Variable Trip Test Point FCI. This design ensures fast, reliable and accurate operation.

    A long-life Lithium Ion battery provides power to indicate the faulted conditions using a high intensity light-emitting diode (LED) display. The unit will flash for a period of four hours after a fault has occurred. After the four hour period, the LED will stop flashing to conserve battery power; however, the unit retains a record of the fault event,and can be interrogated after the four hour period, using the manual testing/reset tool. The unit retains the memory of the fault event until reset manually,or until normal system power is restored.

    Variable Trip 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 systemcomponents exposed to fault currents.

    Universal Power Supply

    The standard S.T.A.R. Low Voltage Reset FCI requires a 120 VAC secondary power source. The S.T.A.R. LVR with Universal Power Supply option can be powered with any secondary voltage source (120,208 or 277 VAC).

  • manufacturer's comment: Cooper Power Systems S.T.A.R.™Low Voltage Reset (LVR) faulted circuit indicators are designed to quickly and easily locate faulted sections of underground cable systems. These faulted circuit indicators (FCIs) can be installed on padmounted distribution transformers or wherever a secondary voltage source is available. The secondary voltage source deriving power from the monitored circuit will provide a known reliable source for operating and resetting the Low Voltage Reset FCI, as compared to current reset devices which are subject to system loading variations. Low Voltage Reset faulted circuit indicators provide a reliable means of fault location and isolation. They also eliminate fault chasing methods which are costly, time consuming, and very stressful on the system components.

  • manufacturer's comment: Working together, SEL fault indicators and distribution protection equipment can identify the location of a fault. When a fault occurs, the SEL feeder relay calculates the fault location as a distance from the substation to the fault, which is communicated to a lineman’s cell phone via the SEL-3010 Event Messenger. However, if a feeder has multiple taps, the relay cannot determine on which tap the fault occurred. SEL fault indicators point to the faulted section of line, which can now be correlated to the fault location provided by the relay.
