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.

Electricity powers modern life, but it also requires strict safety measures. The distribution box, the nerve center of the electrical system, plays a critical role in protecting residential, industrial, and solar installations from hazards such as fire, electric shock, and equipment damage. Join YRO to learn how distribution boxes enhance electrical safety.

As spring warms and flowers bloom, it's the perfect time for the photovoltaic and energy storage industries to gather in Yiwu! YRO sincerely invites you to visit Yiwu International Expo Center from April 27th to 29th, 2025, at our booth E1-B11, to explore the innovative charm of new energy and low voltage electrical equipment together with us.

If you work in the electrical industry, you might be quite familiar with disconnect switches. But in other industry fields, many people do not understand this kind of equipment, and some have not even heard of it. Although this product is not usually mentioned as often as circuit breakers, it is very helpful in ensuring operational safety and compliance with regulations. This article will introduce the uses of disconnect switches in electrical systems and their application in different scenarios.

In power system lightning protection, the lightning arrester's installation location is crucial for transformer protection.

Surge protectors are an important line of defense against sudden voltage spikes, which may damage electrical and electronic equipment and even cause fires. However, many people who are not familiar with lightning arresters often have such a question: Does a lightning arrester need to be grounded to work properly? Next, we will explore the relationship between grounding and surge suppressor.
