Surge Protection Devices For Railways

In the rail transport, both the underground and the above-ground railway or tram transport, attention is turned to the safety and reliability of the traffic, and to the unconditional protection of persons.

Surge Protector Electrical Performance Requirements

Requirements 1. The surge protector should prevent direct contact

Surge Protection For Electronic Products

It is estimated that transients and surges cause 75% of failures in electronic products. Voltage transients and surges are everywhere. Power grids, lightning strikes, blasting, and even people walking on carpets will generate thousands of volts of the electrostatically induced voltage. These are the invisible, deadly killers of electronic products.

Why Gas Discharge Tube Can’t be used between Live and Neutral

Gas Discharge Tube (GDT) has two plates of metals which is separated by inertia gas and then sealed in a porcelain cylinder.

How to choose an SPD

A Surge Protective Device (SPD) is designed to reduce surge voltage, which protects equipment and reduces repair and replacement costs. Every SPD reduces the surge voltage to equipment during a surge to a voltage tested level known as Let-Through-Voltage.

DC surge protection

DC surge protection is necessary in several industries which utilize DC current in order to maintain service functionality. Two major industrial applications of DC surge protection devices is in the telecommunications industry utilizing cell tower structures and in the solar industry utilizing photovoltaic power plants.

How Does SPD (Surge Protection Device) Work?

Surge protective devices (SPDs) are essential devices that protect electrical equipment from damage caused by voltage spikes or surges. These surges, which can be caused by lightning or power outages, can interfere with and even destroy sensitive electronic devices.

Surge Protection Devices (Surge arresters) (SPD)

The Surge Protection Device (SPD) is a component of the electrical installation protection system.

Surge Protector Application

With the rapid development of electronic technology, more attention has been paid to lightning strikes in construction. Thus, more overvoltage protection products into the market, the Surge Protective Device (SPD) is also becoming familiar to people.
