Indicating the conditions of the insulation of electrical networks and equipment is an important element for ensuring efficient protection against electric shocks. A number of models with test voltages up to 5 kV and to 10 kV have been implemented.

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 resistance 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.

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. This kind of testing is most often carried out by small or even one-man electrical service companies. Therefore, the main objective was to design such a device where the high technical parameters would be maintained, while its manufacturing costs would be optimised and reduced compared to those of previous models.

It should be emphasized that both the functionality and ergonomics result from collaboration with the present users of meters manufactured by Sonel S. This international event covers the sector for energy production, electricity distribution, energy storage and management, as well as the lighting industry. Easily locate cables and pipes with pinpoint accuracy. The complexity of large underground utilities networks is continually increasing.

So obtaining precise information on the location of specific buried cables and pipes has never been so important in order to protect burried assets during ground excavation work and supporting the mapping and surveying of these existing The PowerTest Trade Show!
