  • What Is an Over and Under Voltage Protector?

    In power systems, voltage abnormalities are one of the main causes of equipment damage and safety hazards. Some people's devices fail to operate properly, while others get burned out—these malfunctions are directly related to voltage issues.

  • What Can a Surge Arrester Do That a Circuit Breaker Can't?

    Modern power systems are threatened by transient voltage surges. These short, high amplitude voltage pulses, usually lasting from nanoseconds to milliseconds, caused by lightning strikes, grid fluctuations or the switching of industrial equipment, can silently destroy precision electronic devices ranging from laptops to photovoltaic inverters. Although circuit breakers are crucial for preventing overloads and short circuits, they are powerless against microsecond-level surges that bypass their mechanical tripping mechanisms. This article will delve into the functions that lightning arresters can perform but circuit breakers cannot, as well as why both are indispensable in electrical protection.
