LCM500 Leakage Current Monitor ® on-line assessment of surge arresters • Safe and effective assessment of MOSA • Wireless sensors • For non-invasive routine surveys of substations • According to IEC 60099-5 method B2 • Advanced user-friendly diagnostic tool • Perfect for Condition Based Maintenance (CBM) program LCM500 Features The new LCM500 System features the following benefits for handling all your surge arrester monitoring needs: Portable Instrument for inspection of surge arresters for condition assessment on a regular basis. New LCM500 is battery operated. Arrester ID Unique identification of each surge arrester makes Data Management easy. LCM500 can store 1000 surge arrester ID’s and measurements performed in the field. Data Management Secured through new Windows© LCM500 Software handling all your surge arrester readings. Defines individual surge arrester types including operational parameters. Software includes e.g. possibility to perform evaluation of groups of surge arresters e.g. same type of arresters or alternatively for a region. Cost effective Inspection of a surge arrester takes less than 10 minutes on location and can be performed with the arrester in live operation (no disturbance of power distribution). Continuous Monitoring LCM500 can be used for continuous monitoring of one or more arresters to investigate details in leakage current changes versus time. Can also be used for continuous registration in substations of big importance to the system operation reliability. Available solutions include on-line configurations using modem communication between LCM500 instrument and PC software.

LCm500 LCM500 – The Technique Well-proven and acknowledged monitoring technique using third-order harmonic analysis with compensation. Rated according IEC 60099-5 as the best field monitoring technique for Metal Oxide Surge Arresters (MOSA). LCM500 records operating voltage and temperature during field measurements. The LCM500 measurements are automatically normalized to standard ambient temperature (+20°C) and 0.7x rated arrester voltage based on recorded temperature and operating voltage during field measurement. Measurements performed under different conditions can thereby easily be...
