DC Surge protective device,protect against lightning surge voltages in solar system (photovoltaic power supply system). These units must be installed in parallel on the DC networks to be protected and provide common and different modes protection. Its installed location are recommended at both ends of the DC power supply line (solar panel side and incerter/converter side), especially if the line routing is external and long. High energy MOVs equipped with specific thermal disconnectors and related failure indicators.
AC Surge Protective Device is an indispensable device for lightning protection of electronic equipment. Its main function is to limit the transient overvoltage that penetrates into power lines and signal transmission lines to the voltage range that the equipment or system can withstand, or to release strong lightning current to the ground, thereby protecting the protected […]
ommon mode SPD between phase and PE or phase and PEN is installed whatever type of system earthing arrangement (see Fig. 1). The neutral earthing resistor R1 used for the pylons has a lower resistance than the earthing resistor R2 used for the installation. The lightning current will flow through circuit ABCD to earth via […]
Solar connectors are an essential part of any solar panel installation. They allow for the transfer of electricity from the panels to the inverter and then on to the grid or battery system. There are many different components that make up a solar connector system, including the male metal crimp, the male plastic housing, the female […]
