DC SPD is cost-effective and provides a solution to improve the system and eliminate any damage caused by surges. It is highly suitable for any facility. It can be used anywhere in the house for protection. These are installed on circuit breakers and automatic transfer switch for portable generator in residential homes and other places like pad-mounted transformers.
Circuit breakers are necessary, and many experts need them to prevent circuit fire caused by short circuit current. Miniature circuit breakers are known to protect only from voltage spikes for a short period, whereas the circuit breaker protects overcurrent in the wiring. If there is over-voltage, it can damage the appliance. However, over-voltage will not cause any fire if a circuit breaker is powering it. Circuit breakers protect from overcurrent, which can even burn down the house, and this may even happen without overvoltage.
Surge protection devices (SPD) and surge arresters have the same function: they can protect electrical equipment from overvoltage conditions, but what is the difference between them? The following is a brief description of the differences between them. 1. Different Rated Voltages; 2. Different Applications; 3. Different installation positions; 4. Different Discharge Current Capacity; 5. Different materials; 6. Different sizes.
In spite of the high lightning risk that many PV installations are exposed to, they can be protected by the application of DC SPDs and a properly engineered lightning protection system.
