    Abstract: A streetlamp fault detection apparatus and a streetlamp fault detection method thereof are provided. The streetlamp fault detection apparatus is coupled to a streetlamp loop, and stores an impedance condition table defining a reference impedance range and a non-reference impedance range. The streetlamp fault detection apparatus measures a total impedance value of the streetlamp loop in a measurement period, determines that the streetlamp loop is in a normal operating state if the total impedance value stably falls within the reference impedance range in the measurement period, and determines that the streetlamp loop is in a fault state if the total impedance value falls into the non-reference impedance range in the measurement period.

    Abstract translation: 提供了路灯故障检测装置及其路灯故障检测方法。 路灯故障检测装置耦合到路灯环路，并存储限定参考阻抗范围和非参考阻抗范围的阻抗条件表。 路灯故障检测装置在测量周期中测量路灯环路的总阻抗值，如果总阻抗值稳定地落在测量周期内的参考阻抗范围内，则确定路灯环路处于正常工作状态，并且确定 如果在测量周期内总阻抗值落入非参考阻抗范围，则路灯环路处于故障状态。
