MIC-15k1 Insulation resistance meter

MIC-15k1 meter is designed to measure insulation resistance of power objects, i.e. single- and multicore cables, transformers, motors and generators, capacitors, switches and other devices  installed in power stations. It is especially recommended for measurements in areas with very high electromagnetic disturbances, e.g. electrical substations with 1200 kV AC and 500 kV DC.

Manufacturer: SONEL S.A. (Poland).
Features
  • Partial discharge indicator PDI
  • Diagnostics of insulation systems based on standard measurements of IR, DAR, PI, SV, RT, DD
  • It allows testing the electrical durability of the tested object - breakdown voltage indication
  • High resistance to electromagnetic interferences guarantees uninterrupted work in power stations and in close proximity to high voltage transmission lines up to 1200 kV AC and 500 kV DC
  • The function of smooth voltage rise in time (RT - Ramp Test) allows to state the partial discharges in the facility and to carry out a partial location of their occurrence
  • Efficient converter with a power of ~150 W that enables insulation burnout, allowing for pinpointing the location of cables and wires short circuit
  • Compatible with external software
