SONEL-MIC-15k1 Insulation Resistance Meter
Insulation analysis within wide range
The Sonel MIC-15K1 insulation resistance meter has been designed to measure insulation resistance of electrical power engineering objects, including single and multi-core cables, transformers, motors and generators, condensers, circuit breakers and other power station equipment. It is especially recommended for measurements in areas with very high electromagnetic disturbances, e.g. at substations with a voltage of 1200 kV AC or 500 kV DC. Due to the measuring voltage of 15 kV (in accordance with the guidelines of ANSI/NETA ATS-2009 TABLE 100.1 standards) the meter can be used for objects with nominal voltage above 34.5 kV.
The MIC-15k1 is an extremely modern, ergonomic device with intuitive operation. It will satisfy even the most demanding measuring engineers in the most difficult conditions, with large disturbances, where other meters will be useless.
- 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 800 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 using one of the following:
- visual method (if power cables are visible along the entire length),
- reflectometric methods, seismic-acoustic waves detector, or with A-frame to indicate direction of the fault (the conductor must be buried in the ground with earth direct contact).
- Compatible with external software
