Surge protective decives, also known as lightning arresters, are electronic device that provide safety protection for various electronic equipment, instrumentation, and communication lines. When a surge current or voltage is suddenly generated in an electrical circuit or communication lines due to external interference, thesurge protective decives can conduct the shunt in a very short period of time, thereby avoiding the damage of the surge to other equipment in the circuit. The surge protective decives are suitable for the requirements of surge protection in domestic residential, tertiary industry and industrial fields. The followings are the features of surge protective decives.
1. The protection flow of the surge protective decives is large, the residual pressure is extremely low, and the response time is fast.
2. The surge protective decives adopt the latest arc extinguishing technology to completely avoid fire.
3. The surge protective decives adopt temperature control protection circuit and built-in thermal protection.
4. The surge protective deciveshave power status indicators to indicate the working state of the surge protectors.
5. The surge protective decives have rigorous structure and stable and reliable performance.
A surge protective device (SPD) is designed to protect electrical systems and equipment from surge events by limiting transient voltages and diverting surge currents. Surges can originate externally, most intensely by lightning, or internally by the switching of electrical loads. The sources of these internal surges, which account for 65% of all transients, can include […]
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 […]
Knowing individual surge components is helpful to understand, but what drives the standards for SPDs are performance aspects or features for each device. After identifying the power distribution system to which the SPD is to be connected, one should compare different available devices by the following: 1. Maximum Continuous Operating Voltage (MCOV). The MCOV is the […]
