Indicating the conditions of the insulation of electrical networks and equipment is an important element for ensuring efficient protection against electric shocks. Recently, the company, SONEL S.A., has been working hard on the development and production of state-of-the art devices for such testing. 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-2501, 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 optimized 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.A. The device has been designed in compliance with PN-EN 61557- 2 and allows insulation resistance testing to be performed as described in, amongst others, PN-HD 60364-6 and PN-EN 04700.

Besides the conventional measurement of insulation resistances up to 5 TΩ, its features allow to automatically measure both the polarization index and dielectric absorption index, thus significantly simplifying testing of transformers. This insulation tester is a portable, battery-powered equipment. Test voltage may be chosen from 500 V up to 5 kV in 100 V increments. Due to its measurement principle (actual voltage and current readings) the accuracy of resistance measurement is not affected by any test voltage error. Nevertheless, the high-voltage generator is electronically stabilized with a better than 2 % accuracy in open-circuit condition and for any normal operation battery voltage. The built-in chronometer automatically counts the elapsed time since the start of measurement. Measured values are transmitted through the USB interface and are printed in the built-in printer as a registration of the performed test. Furthermore, the measured values are stored in a non-volatile internal memory. Up to 4000 measured values may be stored to be transferred afterward to a computer running the T-Logger program.

The real time clock and calendar, and the sequential test number facilitates the identification of each test and the organization of a predictive maintenance system by trend analysis. Some other advanced features are useful to run the most sophisticated insulation analysis. Step voltage test, configurable pass / fail test and timed measurements are automatically performed, with a very simple and user-friendly setup. The measurement parameters are stored in the non-volatile memory for an easy configuration. In order to guarantee the operator safety, the cabinet is made of a high breakdown strength plastic. High security output terminals are placed in the furthest and most protected area of the equipment. A light indicator shows high-voltage presence and is switched-off when the capacities (both internal and external) are discharged up to reaching a safe value. The MD5060x is powered by a rechargeable LFP battery and has an automatic charger that may be connected to 100 240 V mains supply (AC Adapter).
