Single Phase Protection ESDAL MQG (Metal-Oxide Gas Discharge Arrester) are widely used in high voltage power systems to protect buildings, as well as other transformers, motors and electrical equipment from electrical power system transients. This type of device is designed to provide protection for sensitive systems and components in a variety of environments. It is designed to detect and arrest high frequency transients on a range of high-voltage power lines.

The ESDAL MQG is a single phase protection device which is designed to provide an optimal combination of surge protection, insulation distance and electrical arc performance. The device is designed and certified according to IEC 61643-1 and IEC 61480-1 standards, ensuring the highest level of protection that is available from a single device.

The ESDAL MQG consists of two main components: the surge protection element and the insulation element. The surge protection element is a metal oxide gas discharge arrester that is designed to provide protection from high frequency transients on a range of high-voltage power lines. The insulation element is a gas discharged resistor that is designed to provide a capacitive effect in order to improve the surge protection efficiency of the device.

The surge protection element works by detecting the high voltage transients and regulating the current flow through it. When the voltage level of the transient exceeds the absolute maximum voltage value of the device, the surge protection element will conduct, protecting the system from the high-frequency transient. The insulation element works by providing a capacitive effect which reduces the amplitude of the transient and helps to isolate the system from the resulting generated surge.

The ESDAL MQG also features a built-in safety upper-limit voltage, which is designed to protect the system from voltage levels that exceed the device limits. This is done by providing an over- voltage protection device which limits the maximum voltage level that will be allowed through the device. This allows the ESDAL MQG to provide an optimal level of both surge protection and insulation performance.

The ESDAL MQG is a very versatile and reliable single-phase protection device. It is designed to provide optimum protection against a range of high frequency transients with a very high level of safety. This makes it an ideal device for a wide range of applications and environments.
