Surge Arrestors

Surge arrestors are essential. Many white goods, televisions, air conditioners, kitchen appliances and stereos are damaged due to power surges. An overvoltage caused by things such as lightning or internal switching can cause irreversible damage, leaving you no choice but to replace your electrical appliances.

A surge arrestor protects networks and electrical devices from these power surges and can ensure you aren’t faced with the costs that come with replacing those big-ticket items.

Looking to have a surge arrestor installed? Maybe you need a current one serviced or repaired?

Mr Emergency can help with a range of surge arrestor services. You will be pleased with our wealth of experience, outstanding service and flexible payment options.

Surge arrestors play a pivotal role in protecting electrical equipment from sudden and unexpected increases in voltage, often referred to as “surges” or “spikes”. These voltage surges can be caused by various factors like lightning strikes, switching of large electrical devices, or electrical faults.

At the heart of a surge arrestor is a component known as a Metal Oxide Varistor (MOV). The MOV is designed to be an excellent conductor at high voltages and an insulator at normal voltages. Under standard operating conditions, the MOV remains dormant and doesn’t interfere with the flow of electricity.

However, when a voltage surge occurs, the MOV reacts almost instantaneously. It becomes a low-resistance path for the excessive voltage, directing it safely to the ground and away from sensitive equipment. Once the surge has passed, the MOV returns to its high-resistance state, allowing normal electrical operations to continue.

In essence, a surge arrestor acts like a gatekeeper. It continually monitors the electrical current and instantly reacts to any anomalies, ensuring that only safe voltage levels reach your devices. By doing so, it safeguards your appliances and electronic devices from the damage or degradation that can result from voltage spikes.

Surge arrestors come in various types, each tailored to address specific needs and scenarios in electrical protection. Understanding the types and functions of surge protective devices is key to ensuring optimal safeguarding of your equipment.

• Station class surge arrestors: Designed for high-voltage applications, station class arrestors are commonly used in substations and electrical power stations. They are used to protect against overvoltages from lightning and switching events, ensuring the safety of transformers, circuit breakers, and other vital equipment.
• Intermediate class surge arrestors: Suited for protection in distribution networks, intermediate arrestors offer a balance between high-energy handling capabilities and fast response times. Intermediate arrestors are used on equipment like distribution transformers and feeder lines.
• Distribution class surge arrestors: These are designed to protect electrical distribution systems from lightning-induced surges. They are often installed on poles in residential and commercial areas in case of lightning strikes, which can cause temporary overvoltages.
• Secondary class surge arrestors: These secondary arrestors are ideal for lower voltage applications, these are primarily found in homes and small businesses. Secondary arrestors defend sensitive electronics like computers, televisions, and refrigerators from minor electrical surges.

Each type of surge arrestor functions to divert the voltage surge current away from equipment, channelling it safely to the ground. By choosing the appropriate arrestor for a given application, you ensure effective protection against potential voltage threats and prolong the lifespan of your electrical devices.
