PRODUCT BRIEF Cooper Power Systems manufactures a line of Superior, Tough And Reliable faulted circuit indicators to fit your application. BULLETIN B320-97035 S.T.A.R.™ Low Voltage Reset Type Faulted Circuit Indicators A Reliable and Highly Visible Means of Detecting Underground Faults Quickly Description: Cooper Power Systems’ S.T.A.R. Low Voltage Reset (LVR) faulted circuit indicators (FCIs) can be installed on pad-mounted distribution transformers, or at a secondary voltage source. The unit automatically resets to the normal position when circuit voltage is restored. The S.T.A.R. LVR FCI is comprised of a sensor, a remote display and a secondary power cable. A six foot fiber optic cable connects the sensor to the display, eliminating any electrical or metallic connection between the primary side and the secondary side of the transformer. The FISHEYE™ display, with a highly reflective orange target, provides enhanced 180 degree visibility for remote indication. The display fits a standard remote indicator window used on pad- mounted transformers. The display is black under normal conditions. The selection of a LVR faulted circuit indicator has never been easier! For conventional indicators, trip ratings are selected based on cable diameter, load current and minimum fault current levels. Trip rating selection for S.T.A.R. faulted circuit indicators has been reduced to two simple choices. For a 200 A URD circuit, select a “LO” trip rating. For a 600 A distribution system, select a “HI” trip rating. This approach to trip selection means that one indicator fits all cable diameters from 0.7” through 2.0”. With this simplified approach to rating selection: ■ Ordering is easier and reduces lead times. ■ 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. For SCADA applications, auxiliary contacts can be added. The magnetic latching circuit that operates the auxiliary contact ensures a reliable indication. Design Features: These design features are standard on every S.T.A.R. faulted circuit indicator: ■ Inrush Restraint: Eliminates false tripping due to recloser operations ■ Low Pass Filter: Prevents tripping on high frequency transients ■ Temperature Compensation Circuitry: Assures accurate, reliable performance over a wide temperature range ■ Reliable Open Core CT Design: Eliminates tripping due to adjacent magnetic fields ■ Quick Response Time: Coordinates with all current-limiting fuses ■ Tough, Durable Construction: Corrosion-proof, damage-resistant, display status cannot mechanically change ■ Exceeds ANSI®/IEEE Standard 495-1986™ ■ Quick and Easy Installation: Only one hot stick is required PRODUCT BRIEF S.T.A.R.™ Low Voltage Reset Type Faulted Circuit Indicators Electrical Ratings and Characteristics: Description Power Requirements Reset Requirements Reset Time Trip Current Trip Accuracy Trip Response Speed Maximum Continuous Load Current Fault Withstand Capability Cable Size Temperature Range Materials Weight Auxiliary Contact Ratings Ratings and Characteristics 105 VAC, 15 mA @ 120 VAC 87 VAC minimum 6 to 9 seconds Factory Preset, (High and Low) +/- 10% Response Curve, Figure 4, Sec. 320-50 600 A 25 kA for 10 cycles per ANSI®/IEEE 495-1986™ #2 to 1000 MCM, Insulated -40˚ C to +85˚ C Corrosion-resistant & submersible per ANSI®/IEEE 495-1986™ 26.7 ounces (0.76 kg) 1A 30 VDC 0.5 A 125 VAC 0.3 A 110 VAC 5.2” (132 mm) 3.7” (94 mm) 2.0” (51 mm) .6” (14 mm) 4.4” (112 mm) 3.6” (91 mm) .41” (10 mm) 2.5” (64 mm) 5.7” (145 mm) 1.8” (46 mm) SENSOR .42” (11 mm) 2.2” (56 mm) 1.75” (45 mm) SECONDARY POWER CABLE 1.4” (36 mm) REMOTE DISPLAY Because we’ve incorporated so many “custom” features into our standard design, we’ve drastically reduced the part numbers.
