Product Description Product Description1.Introduction Overview: Good solution of the pinpointing of single phase to earth faultIt applies to overhead line small current grounding power system.It is use to pinpoint the earth fault when line break down when single phase grounding fault happen.The kit includes transmitter (OGFL-200T), senor (OGFL-200S) and receiver (OGFL-200R) and the accessories. After the overhead line stop running, the transmitter will inject ultralow frequency HV signal to the line to reappear the fault. Detect along with the line by the sensor and it will transmit data to the receiver by wireless mode. The receiver will collect and display this detect result. When detect before fault point, the current will continue but after the fault, the current will can't be tested.First use this device to find the fault by areal survey, then pinpoint to find the fault point. 2.Product Pictures 3.Function features:Apply to small current neutral grounding distribution power system. It is used to detect the over head line metallic grounding fault, arc grounding fault, resistance grounding fault and so on.Workable for broke down line, apply for branch lineUltralow frequency signal to avoid capacitor influence. Easy to find the high resistance fault Recreate fault by high voltage signal, easy to locateSafe transmitter by black and short-circuit functionHigh sensitive sensor, open design and easy to hang on the lineWireless transmission, safe and reliableFlexible power supply. Transmitter is workable by Utility power and electric generator. Sensor and receiver are by dry batteryLight and easy to carryReceiver has large LCD display interface, which can show the current waveform and current value 4.SpecificationLocation accuracy:0.2mSpecification of transmitter: *open-circuit voltage: fundamental wave valid 0~2800kV (impulse DC, peak value 8kV,amount to the phase voltage peak value of 10kV cable) *short-circuit current: fundamental wave valid 0~35mA(impulse DC, peak value 100mA ) *output frequency1HzCommunication distance between receiver and transmitter: no less than 100mTransmitter power: AC 220V,or electric generator (output voltage ≥1500W)Transmitter power: Max. 900 WSensor supply power: Three AAA alkaline batteriesReceiver supply power: Five AA alkaline batteriesDimension: transmitter 417mmx234mmx318mm *Sensor 180mmx100mmx35mm *Receiver 205mmx100mmx35mmWeight: transmitter 16.8kg *Sensor 0.45kg *Receiver 0.45kgWorking condition : *Temperature -10oC-40oC * Humidity 5-90% * Elevation ≤4500mCompany introduction1.certificationWe have passed ISO9001:2015,CE,SGS approval and IEC report2.Company profile Tianjin Grewin is concentrating on transformers for 20 Years and complianted by ISO9001:2015,CB,IEC CB,CE etc.We're always pay great attention to its business philosophy "Quality and Honesty First".Grewin is specialized in the design and manufacture of wound components such as transformer,current sensors, chokes etc .windely used in communications,electronics,meters,industrial control,medical equipments and other fields.We are also a provider of power meters and instruments locators. 85% of its products exported to America, Europe, and Asia etc.We sincerely invite you to join us to create a bright future.3.Terms of Shipment:Within 10 working days after received related prepayment or L/C.4.Payment terms:(1)T/T 100% or 50% deposit by T/T in advance, balance amount to be paid 7 days beforedelivery.(2) By irrevocable L/C at sight, to be issued immediately against confirmed order.(3)Payment by T/T, if order amount is less than USD 20,000.5.Warranty:(1)We provide 1 year warranty.(2)If the product is defective, please notify us within 3 days of delivery.(3)All products must be returned on their original condition, in order to qualify for a refund or exchange of goods6.Why choose us?Quality and honest first!A.
