Electric safety as a basic requirement Further to carrying out their function, devices for electric measurement must focus on the operator's safety as a basic requirement as regards protection from instant overvoltage which may generate because of the presence of complex charging networks, short circuits, atmospheric charges, etc... In this respect, international standard IEC 61010-1 harmonized in Europe with EN 61010-1 has devised precise rules which electric devices used for measurements in LV (<1000VAC) must comply with. Four "Overvoltage Categories" were created, which define the...

PHOTOVOLTAIC TESTERS FOR THE SUN New HT solutions for performance optimization and troubleshooting. PHOTOVOLTAIC TESTERS Thanks to the decrease in the cost of components and the remarkable increase of performance, installing photovoltaic systems on the roof or on the ground has become increasingly common. In a photovoltaic system, problems connected to safety and to the system’s performance must be checked, and maintenance of strings and single panels must be carried out. Troubleshooting › I t may happen that, during the operation of a system, some modules may jeopardize the performance of...
