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.
Electrical networks are low-frequency and, as a result, propagation of the voltage wave is instantaneous relative to the frequency of the phenomenon: at any point of a conductor, the instantaneous voltage is the same. The lightning wave is a high-frequency phenomenon (several hundred kHz to a MHz): 1. The lightning wave is propagated along a […]
Are you worried about your electronic devices getting fried due to voltage spikes? Well, worry no more! We have the answer for you – the surge protective device. A surge protective device, or SPD, is a device that is designed to protect electrical equipment from voltage spikes or surges. These spikes can be caused by […]
