  • Transformer Diagnostics and Condition Assesment

    Doble Power Factor. A good indication of insulation deterioration is a slowly rising power factor. Doble insulation testing is an important step in determining the condition of the transformer because it can detect loss of winding insulation integrity, loss of bushing insulation integrity, and winding moisture. Excitation Current. Doble test equipment is also used to conduct excitation current tests, which can detect short-circuited turns, poor electrical connections, core de-laminations, core lamination shorts, tap changer problems, and other possible core and winding problems. Turns Ratio (TTR) The turns ratio test detects shorted turns, which indicate insulation failure by determining if the correct turns ratio exists. Shorted turns may result from short circuits or dielectric (insulation) failures. Leakage Reactance. This is normally an acceptance test to see that nameplate percent impedance matches with the measured percent impedance when the transformer arrives from the factory.

  • AC Current Monitoring Data Logger : 9 Steps (with Pictures

    To get the data I used a ceramic 1k variable resistor (rheostat), and 12v transformer to step down the mains AC voltage from 240V, which will gave me generate a variable current source from 13mA to 100mA. The more data points collected the better, however I'd suggest collecting 10 data points to gain an accurate trend.

  • Measuring 240 Vac Residential with One Current Transformer

    Option One: Neutral AvailableOption Two: No NeutralScalingIssuesIf neutral is available, you can monitor one-half of the load by using the WNB-3Y-208-P, WNC-3Y-208-FT10, or WNC-3Y-208-MB models (they require neutral for the internal power supply). Connect ground and neutral as usual, then connect one of the two lines (L1 or L2) to the WattNode meter ØA (phase A) input. Place a CT around the same line being monitored by ØA and connect the CT to the ØA CTinput. You can use the phase B and C inputs to monitor two additional loads if desired. The WattNode Pulse, Option P3allows each phase to be monitored independently. The WattNode Modbus and WattNode LonWorks meters provide per-phase outputs, which allow each phase to be independently measured. 1. You will need to scale the readings to correct for only using one CT. See Scalingbelow for details. 2. See Issuesbelow for notes on the accuracy of this approach and other issues.
