Therefore, with a large group of electricians in mind who test receiving end electrical systems in the broadly defined municipal infrastructure, industries, office buildings or private housing — Sonel MIC, a new insulation resistance tester has been designed and launched onto the market.

It should be emphasized that both the functionality and ergonomics result from collaboration with the present users of meters manufactured by Sonel S.

We offer and deliver for revision engineers, service and installation specialists whole range of measuring devices of Sonel Co. Two- or three-lead insulation resistance measurement Selectable measurement voltage from the range to V in V steps Acoustic determination of five-second periods of time Measuring T1, T2 and T3 times to determine absorption coefficients for 15, 60 and s, indication of actual test voltage during measurement, protection against measuring live objects Low voltage measurement of circuit continuity and resistance: We are working in accordance with ISO Regarding assortment of Lumel Cowe offer and deliver devices for energetics, analog and digital devices for switch board producers, transducers of electric signals, analysers and recording devices, current transformers and shunts, operator panels and display.

Indicating the conditions of the insulation of electrical networks and equipment is an important element for ensuring efficient protection against pn–en shocks.

Therefore, the main objective was to design such a device where the high technical parameters would be maintained, while its manufacturing costs would be optimized and reduced compared to those of previous models.

Due to extended measurement functions and immunity to electric fields and other interferences, they are one of the leading products used in professional power engineering for complex and advanced insulation resistance testing.

Common insulation pn-eh tests carried out in receiving end of the electrical grids do not require such extended measurement functions, as this leads to an increase in the overall dimensions of the device. This kind of testing is most often carried out by small or even one-man electrical service companies.

A number of models with test voltages up to 5 kV and to 10 kV have been implemented.
