UNUSED SURPLUS QEI LVT 8040 VOLTAGE TRANSPONDER THESE WERE NEVER INSTALLED ANYWHERE THESE ARE IN GREAT SHAPE AND READY FOR INSTALLATION CONTACT ME IF INTERESTED IN QUANTITIES FOR SEPERATE AUCTION LVT-8040 Line Voltage Transponder The LVT-8040 is a pole or wall mounted unit in a rugged outdoor enclosure which measures and stores power line voltage information at points along power feeder lines downstream from the substation. End-of-line voltage measurement by LVT's can be used to directly control regulation at the substations. 24 hour survey data stored by LVT's provides information for long range planning in load management schemes or reconfiguration of the distribution system. The LVT-8040 uses 5,180 Hz carrier for two-way communication over the primary and secondary power distribution lines emanating from utility's substation and eliminates the need to install or lease separate communication facilities or to dispatch personnel to pick up the readings. Each LVT can report: the current voltage; the minimum and maximum voltages during a weekly or monthly period; and a daily 24 hour survey. Specifications 120V range 240V range Input Range: 100 to 135 VRMS 200 to 270 VRMS Accuracy: ±.2 volt ±.4 volt Sample Rate: 1 sec. 1 sec.
