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.


Advantages:

Ø The least influence from external magnetic field and noise by triple shielding for CT.

Ø Measurement with a resolution of 100nA with maximum accuracy.

Ø Harmonic current measurement.

Ø Easy & fast operation.

Ø Measurement of true RMS leakage current (Dominant and third harmonic current).

Ø Compliant with IEC 60099-5 method B1.
