This model AL CL-40 L mainly measures very small leakage current of grounding line connected with Arrester etc. The CT which is applied to this model is hardly affected by external magnetic field and therefore model AL CL-40 L can measure leakage current very accurately in high magnetic and electric field.
Features:
CT sensor inside diameter of CT: 40 mm
Measuring Function: Leakage Current, Harmonic Current (Dominant & Third Wave)
