Large transformer jaws of 68mm diameter makes it possible to clamp on all three or four wires (3 phases) together for leakage current measurement. • True RMS enables an accurate measurement for distorted waveforms. • Measurement from mA up toAC 1000A • Frequency filter switch to eliminate the effect of the harmonics. • 2 way analogue output terminal:AC current detected by transformer jaws is converted to AC and DC voltage. Output cord model 7073 (option) is used for monitoring waveform with an oscilloscope or for connecting to a recorder.
3 channel inputs for the simultaneous recording of Leakage Current, Load Current and Voltage • Power Quality analysis(only on KEW 5020)(Power Quality:Reference voltage, Swell, Dip, Short power Interruptions) Large Capacity for storing 60,000 data points 60,000 data points can be recorded when 1ch is used, and when all the three channels are used, 20,000 data points per channel can be recorded Lowpass Filter will filter out the harmonics(Cutoff Frequency = Approx. 160Hz) LED flickers when the preset current / voltage value is exceeded CALL: Confirmation of recorded data • The following can be displayed: number of recorded data points, (max+ min+ peak) value for each channel complete with time/date information in the Normal recording mode. (Detected values (i.e. when values are outside preset limits ) can be displayed in other recording modes) • RECALL: The last 10 recorded data points including time/date can be recalled on the logger display
