To choose the best technology for surge protective devices, we should consider the following technical parameters (include but not limited to): 1. Type of surge protective devices according to EN61643-11/IEC 61643-11 2. Nominal Voltage (Un) 3. Maximum Continuous Operating Voltage (Uc) /Maximum Continuous Operating Voltage for PV System (Ucpv) 4. Voltage Protection Level (Up) 5. Nominal Discharge Current (In) 6. Maximum Discharge […]
The fusewas invented by Edison more than 100 years ago to protect the expensive incandescent lamp. With the development of The Times, fuses protect electrical equipment from the current overheating injury, avoid electronic equipment due to internal failure caused by serious injury. When electric current flows through a conductor, the conductor will heat up because there […]
Surge Protection Devices (SPD) are used for electric power supply networks, telephone networks, and communication and automatic control buses. The Surge Protection Device (SPD) is a component of the electrical installation protection system. This device is connected in parallel on the power supply circuit of the loads that it has to protect (see Fig.1). It […]
