Publish Time: Author: Site Editor Visit: 71

Analysis of common faults in lighting small power distribution units usually requires the following steps:

Appearance inspection: Check whether the box, switch, socket, etc. are obviously damaged or abnormal.

Electrical parameter measurement: Use appropriate electrical test instruments to measure voltage, current and other parameters to confirm whether they meet the normal working range.

Check protective devices: Check whether protective devices such as circuit breakers are working properly and whether there are signs of triggering or damage.

Line inspection: Check whether the wire connections inside and outside the small power distribution unit are loose or heated, and eliminate possible short circuits or poor contacts.

Load analysis: Analyze the load conditions of each circuit to confirm whether there is an overload or unbalanced load.

Temperature detection: Use tools such as infrared thermometers to detect the temperature of various parts of the small power distribution unit to find out whether there is overheating.

Recording and analysis: Record various inspection results and analyze them to identify possible problems and take corresponding repair measures.

Regularly conducting the above analysis on the lighting small power distribution unit can detect and solve various faults in time to ensure the normal operation and safety of the lighting system.
