During routine maintenance of power systems, technicians frequently encounter a challenging situation: How to safely interrupt electrical flow when servicing equipment, while preventing accidents like arc flashes or explosions due to operational errors?It is precisely based on this actual situation that the disconnector, a dedicated device, has been developed and applied.

An isolating switch (also known as an isolator or disconnecting switch) is a high-voltage electrical component designed to provide a reliable, visible disconnection point in a power system. Its core function is to safely isolate a section of equipment—such as a transformer, capacitor bank, or cable—from the live power grid for maintenance, inspection, or circuit switching. Unlike circuit breakers, isolating switches cannot interrupt load current or fault currents (e.g., short-circuit currents). They must be operated only after the circuit has been de-energized or the current has been cut off by a circuit breaker. This makes them essential for creating a safe working environment in high-voltage applications, including renewable energy power stations, substations, and industrial plants.

Dear business partners: When wisteria flowers meet four leaf clovers, China is about to welcome the May Day International Workers' Day. According to the holiday arrangement of The General Office of the State Council of China, YRO will enter the holiday mode from May 1st to May 4th and resume normal work from April 26th to 27th.

It is a common phenomenon to encounter the tripping of the main power circuit breaker during thunderstorms, or when using high-power equipment. However, many users have such a question: Can installing lightning arrester effectively reduce or even prevent such tripping accidents? Anyone who has a basic understanding of surge protectors and circuit breakers knows that, although surge protectors are electrical protection devices, their functions are different from those of circuit breakers. It doesn't matter if you don't understand. This article will take you to deeply understand the role of surge protectors in practical use, and explore whether they can really prevent the main circuit breaker from tripping unexpectedly.

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.
