Leakage and harmonics current Measurements for gapless metal-oxide surge arrester in service

FEATURES

・The least influence from the external magnetic field and noise by shielding for CT.
・Compliant with IEC6099-5.
・Measurement value can be kept in the our cloud server through our APP "Multi-Tracer" by the Blue-tooth. Otherwise connect to our dedicated display unit MDU-200X.
・Enabled the measurement for minimum 0.1μA resolution and harmonics current.
・In addition to measured values, location registration by GPS, temperature, date and time can also be saved.
