The Sonel MIC-15k1 meter is designed to measure insulation resistance of power objects, such as single and multicore cables, transformers, motors and generators and other devices installed in power stations.  It is especially designed for making measurements in areas with very high electromagnetic disturbances, e.g. electrical substations operating up to 1200 kV AC and 500 kV DC. With the 15 kV measuring voltage (in accordance with ANSI / NETA ATS-2009 TABLES 100.1) the meter can be used for measuring objects with a nominal voltage above 34.5 kV.
