There is almost no product that can be produced or brought to market without electricity. Electricity is the basis of our world economy. Electric energy however is a product with qualitative differences.
The quality of electric energy is defined by voltage: It should be in an exact sinus curve in low voltage power systems, with 230 Volt and a constant frequency of 50 Hz. The energy distributor can indeed produce his products with these desired values, but the user will never get these ideal electric current.
The reason therefore lies in the customers themselves because by their behaviour they are to influence the power system quality: With the use of attachments like switching power supplies and frequency converters, harmonics emerge. Those harmonics strain the power system with unexpected voltage and streams. The consequences: Electric controlled machines start working unprecisely, systems switch of, data systems collapse, the light flickers, power systems burn through, computers break down, cables overheat or energy costs raise without any obvious reason. The economic disprofit in Germany might be up into billions every year.

To counteract this situation, the legislator founded the low voltage access regulation (NAV) which was to start on the 1st November 2006. It says every access user has the duty to run the equipment in a way that does not produce interferences for other access users. If defects are discovered anyway, the network operator is authorized to interrupt the access utilization.
The Modl GmbH as a partner of competence helps you to keep accordingly to the NAV restrictions and to save cost over-runs.
Therefore our company offers the following solutions:
Our team is looking forward to helping you and find the perfect solution.
