All About Metal Oxide Surge Arrestors

Metal oxide surge arrestors are crucial in the heavy power generation and rail industry.  By providing surge protection for DC distribution systems, they help keep the power grid running smoothly and efficiently. But how do these devices work? And what are some of the best practices for using them?

Metal oxide surge arrestors work by diverting excess voltage away from sensitive equipment. They’re typically installed at key points in the power system, like rectifiers, substations, and DC feeders. This helps to protect against voltage spikes that could damage or destroy equipment.

When selecting a metal oxide surge arrestor, it’s essential to consider the maximum continuous operating voltage (MCOV). This will help ensure that the device can handle the amount of power being generated. It’s also important to connect the arrestor to an appropriately sized conductor in order to prevent damage from surges.

Surge arrestors use a metal oxide technology that has been proven in the station and intermediate class arrestors. They are designed to operate in temperatures not exceeding 60 degrees Celsius. The arrestor housing is manufactured of impact-resistant UV stabilized polyester glass compounds with the element encapsulated. The element’s encapsulated area also has a high dielectric sleeve for added protection.
