Its main principle is in the aging line line body with five voltage zones such as high-voltage, low-voltage, normal voltage, high-voltage impact, roaming monitoring, etc., to simulate the utility wave voltage of the aging (can also be set up according to the needs of customers in the aging line current detection function).

In the lamps and lanterns through the line body of the voltage detection, observe whether these products can withstand the impact of these voltages, whether there is burst capacitance, short circuit, black head, glow flash lamp phenomenon, to ensure the quality of the product.
