Sonel Insulation Testers are 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.

Features

• Diagnostics of insulation systems based on standard measurements of IR, DAR, PI, SV, RT, DD, widened with thepartial discharge (PD) indicator for every each of these measurements,
• 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 close 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,
• Digital filters function for measurements in high noise environment,
• Measurement of leakage current during insulation resistance testing,
• DC and AC voltage measurement in the range of 0...750 V,
• Drawing graphs on the display during measurement,
• Innovative memory with possibility of description of: measurement points, facilities, names of customers,
• Stable measurements in noisy environments such as 765 kV substations,
• Graphic LCD 5,6'’ backlit,
• Power supply from battery packs,
• Compatible with external software.
