Taurus Multi LCM-40P measures very small leakage current of grounding line connected with lightening arrester. It can measure leakage current very accurately in high magnetic & electric field. It measures the leakage current to warn that an arrester is damaged or deteriorated and should not be energized. It is a diagnostic indicator of Zinc oxide surge arrester in service. It helps in making decision regarding the healthiness of surge arresters.
