Surge arresters, also known as surge protection devices (SPDs) or transient voltage surge suppressors (TVS), are useful components for mitigating the overvoltage transients that can occur in electrical systems. The SAC10 (Surge Arrestor Circuit) is one such device, designed to reduce the high-voltage transients that can occur due to lightning or electromechanical operations. The application field and working principle of SAC10 can be discussed in this paper.

The SAC10 has been designed for application in the neutral-ground subsystems of electrical distribution systems, where electro-mechanical disturbances such as lightning can produce unwanted overvoltages. This type of overvoltage event can damage sensitive electrical and electronic equipment and may cause disruption to operational safety. The SAC10 eliminates such problems by providing a highly effective, low-voltage waveform-tailored neutral-ground surge arrester.

The SAC10 works by dissipating the transient energy associated with the high-voltage surge. It is made up of a pair of capacitors across which a spark-gap is formed with a resistive load in between. The voltage drop across these components is equal to the peak voltage of the incoming surge. As the incoming voltage drops below the peak voltage, the spark-gap begins to allow current to flow across the two capacitors, thus dissipating the surge current. The SAC10 can withstand up to twice the AC load current, making it an effective solution for suppressing severe lightning surges or high-voltage discharges.

The SAC10’s main advantage is its high energy absorption capability, as it can absorb surge energy of up to 10 times the nominal AC line current. The device has been designed to work in temperatures between -40°C and +85°C, thus making it suitable for a wide range of environmental applications. It also has an excellent surge withstand capability, with a minimum of 5,000 operations for a given nominal AC line current.

The primary function of the SAC10 is to protect critical systems from transient overvoltages. It does this through its combination of high-energy absorption and low voltage-drop waveform-tailored design. This helps to reduce the potentially damaging effects of high-energy surges, as well as limit the peak voltage of the incoming waveform. This is particularly important in protecting sensitive electronic and electrical equipment, which can be damaged from the high electrical energy associated with lightning strikes or high-voltage discharges.

The SAC10 is also designed to have a long life and perform reliably. It has been designed using reliable components and has a comprehensive safety certification. This ensures that the device is suitable for use in a wide range of industrial and commercial environments.

In summary, the SAC10 is an effective solution for reducing the effects of transient overvoltages due to lightning strikes or high-voltage discharges. The device has excellent energy absorption capabilities, a wide temperature range, and a long life. It is an ideal choice for protecting sensitive electrical and electronic equipment from the potentially damaging effects of high-energy surges. It also has an excellent surge withstand capability, thus making it suitable for use in a number of different applications. By understanding the working principle and application field of the SAC10, it can be seen that it is an effective solution for mitigating the effects of transient overvoltages in systems.
