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 […]
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 […]
A circuit breaker refers to a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. Circuit breakers can be used […]
