Electrical Testing Instruments - INESSMAN

1 Electrical Testing Instrumentsfrom ADWEL International Ltd. A compact instrument forprecise determination ofcapacitance and dissipationfactor (power factor). An important tool forpreventive maintenance,production Testing , cablefault finding. Extremely useful for measuringdielectric properties of powertransformers, bushings, cables,motors and breakers. Wide Range (10pF - 100 F)Capacitance DF BridgeModel TCB-100By the use of a well proven transformer ratio-arm design,we have produced a bridge which performs measurementsin conditions that are beyond the scope of mostconventional Capacitance sites such as high voltage switch yards, transformerstations, and production areas with a high presence ofelectrostatic interference present no problem to thisinstrument.

2 Measurements on three or four terminaldevices can be done without calculation by the use of theGUARD low voltage test set is designed to test electricalinsulation qualities in the laboratory, substation ormaintenance shop, without the dangers associated with ahigh voltage test are in pF with decimal multiplication unique selector switch allows selection of all possiblecombinations without changing the initial hook-upconnection on the item under extremely sensitive NULL Detector is sharply tuned tothe test frequency. It also rejects line frequencyinterference test set is easy to use, and requires no calculation orcomplicated multiplication of subject to change without noticePower inputRangesAccuracyResolutionTest FrequencyNull DetectorTest VoltageHousingDimensionsWeightEnvironmen talApproval120V or 230V, 50/60 HzSensitive Circuit Breaker to protect instrumentCapacitance - 10 pF to F in 4 rangesDissipation Factor - to direct reading+30% added in steps of 10%Capacitance - of range 10 pFDissipation Factor - 1% or reading.
