Voltage Current Protector

The fault arc protector identifies normal switch operation arcs and abnormal fault arcs by detecting the current and voltage waveforms in the circuit. A normal arc is a brief arc generated during normal switching operations of electrical appliances, such as plugging and unplugging plugs or switching electrical appliances; And the fault arc is usually caused by abnormal arcs due to aging of the circuit, insulation damage, poor contact, electrical faults, and other reasons. When a faulty arc is detected, the protector will quickly cut off the circuit to prevent dangerous situations such as fires caused by the arc.

What is arc protection device?

Arc protection device is a device specifically designed to detect and protect electrical systems from the effects of arc faults. It mainly identifies potential arc faults by detecting arc light and sudden changes in current, and quickly cuts off the circuit before the fault occurs, thereby preventing equipment damage and fire.

What are the main applications of fault arc protectors?

Arc protection devices are widely used in power systems such as medium and low voltage switchgear and substations, and are particularly important in the following scenarios:
Medium and low voltage switchgear: used to detect and quickly cut off arc phenomena caused by short circuit faults, avoiding equipment damage and personnel injury,
Substation: Protecting critical equipment from arc faults and ensuring stable operation of the power system.

What is the function of an arc protector?

Arc protectors are essential in electrical equipment as they can provide excellent safety protection. It can effectively prevent electrical accidents and ensure the safety of employees’ lives. Installing arc protectors in electrical equipment is also one of the necessary means to ensure the production safety of enterprises.
