Common Faults Of Garden Lights

There are two types of common faults: one is high-impedance faults; The other category is low-impedance faults. The so-called high-resistance fault, that is, the cable is burned, the measurement resistance of the instrument is large, or the insulation decreases between phases or to the ground, but there is a certain resistance; The so-called low-impedance fault, that is, the conductor is shorted or completely shorted to the ground, the current increases, and the power transmission trips. These two faults and their frequent occurrence pose a threat to the normal use of garden lights. Therefore, full attention must be paid to identifying the causes and countermeasures.
