PRODUCTS
New 3CT method for AC leakage current measurements Model MCL-4000F This is new measuring method for AC leakage current measurement of 3phase/3wire or 3phase/4wire power system. It is useful when working at the field where it is difficult to clamp the whole phase conductors.
FEATURES 3CT method enabled easy AC leakage current measurements with simple clamping of each phase conductor by 3 CTs or 4 CTs. Use 4 CTs for 3phase/4wire power system. Load current measurements for each phase conductor up to AC 800A. Filter rejection for high frequency noise. DC mV output for recorder.
