The leakage protection detection of rural lighting split meter ready boards is an important part of ensuring rural electricity safety. Here are some effective methods for detecting leakage protection:

Preliminary inspection: Firstly, the internal wiring connections of the split meter ready board should be checked for firmness and for any obvious signs of burning or damage. At the same time, observe whether there is water or moisture in the split meter ready board, especially in old split meter ready boards, and check whether their sealing is good. Disconnect the electrical switches in the split meter ready board one by one, observe whether the leakage phenomenon disappears, and determine whether the leakage is caused by a specific electrical appliance or circuit through elimination method.

Measure with a clamp gauge: Set the clamp gauge to AC current mode and clamp the live and neutral wires simultaneously. If the reading is not zero, it indicates the presence of leakage. This method is simple and fast, suitable for rapid detection.

Power off measurement method: Turn off all power sources, set the multimeter to high resistance mode, with one probe receiving the live wire and the other probe grounded (or tap). If the displayed resistance is not infinite, it indicates the presence of leakage. This method can accurately determine the leakage situation, but attention should be paid to power-off operation to ensure safety.

Live measurement method: Under live conditions, use a multimeter to measure the suspected leakage of electrical appliances in the AC voltage range on the metal casing, with one probe connected to the casing and the other probe grounded (or tap). If the reading is higher than 30 volts, it indicates the presence of leakage. However, it should be noted that live measurement carries certain risks, and it is recommended to have a professional electrician operate it.

Use professional testing instruments: For complex leakage problems, professional testing instruments such as high-frequency impedance testers and high-voltage harmonic testers can be used for testing. These instruments can provide more accurate measurement results, which helps to quickly locate the leakage point.

When conducting leakage protection testing, it is essential to ensure personal safety and wear necessary protective equipment such as insulated gloves, insulated shoes, etc. For non professionals, it is recommended to entrust professional institutions to conduct testing.
