Metal Oxide Varistors (MOVs) are essential components in electrical systems, designed to protect sensitive equipment from damaging voltage surges. These devices operate on a simple yet effective principle: they exhibit high resistance under normal voltage conditions but rapidly decrease their resistance when exposed to high-voltage transients. This allows them to divert excess energy away from the protected equipment, safeguarding it from potential damage.
How Does a Metal Oxide Varistor (MOV) Surge Arrester Work?
● Normal Operation: Under normal operating conditions, the MOV presents a high impedance, allowing only a minimal amount of current to flow through it.
● Surge Event: When a voltage surge occurs, the MOV's resistance decreases dramatically, allowing it to conduct the excess energy to ground.
● Energy Dissipation: The MOV absorbs the surge energy and dissipates it as heat, protecting the connected equipment.
Key Components of an MOV Surge Arrester
An MOV surge arrester consists of several critical components that work together to safeguard your electrical systems:
● Metal Oxide Varistor Disk: The core component, made of zinc oxide and other metal oxides, which exhibits nonlinear voltage-current characteristics.
● Electrodes: Conductors that connect the MOV disk to the external circuit.
● Encapsulation: A protective housing that encloses the MOV disk and electrodes, shielding them from environmental factors.
● Terminals: Connect the surge arrester to the electrical system.
