Description

The surge arrester is an advanced protective device designed to safeguard electrical equipment from over-voltage transients, such as lightning strikes or switching surges. Utilizing cutting-edge ZnO (zinc oxide) technology, this arrester significantly enhances voltage-current (V-A) characteristics compared to traditional carborundum arresters. By incorporating metal oxides, it achieves superior performance and improves the ability to withstand high voltage conditions. When operating under normal voltage, the current passing through the arrester remains minimal. However, during an over-voltage event, the arrester’s remarkable non-linear V-A characteristics enable it to channel thousands of amperes instantly, effectively dissipating excess voltage energy and minimizing potential damage to power transmission equipment.
