KPM LA 103 Pro

KPM LA 103 Pro
Advanced On-Line Test System for Residual Life Assessment of Metal Oxide Surge Arresters — keeping your infrastructure protected without interruption.
 The KPM LA 103 Pro is an on-line test system that measures and displays the values of Total Leakage Current and Third Harmonic Resistive Leakage Current directly. It provides system harmonic compensation as per IEC 60099-5-B2, and delivers Corrected Resistive Leakage Current after applying correction factors for changes in system voltage and temperature.
KPM LA 103 Pro can measure arrester condition while still in service — assessing the quality of the metal oxide blocks and helping manage the risk of failure. It takes less than 10 minutes to establish
