Į Metodas Aptikimas Nuotėkis Srovė Vidinis Paslėptas Linijos Su Spaustukas Ammetras
1. Spaustukas ampermetras is a specialus įrankis for matavimas AC srovė. Matavimas srovė su a spaustuku ampermetru negali tiksliai atskirti elektra vogti elgtis, nes ten yra daug ir sudėtinga priemonės of stealing electricity.
2. Just take the case of "bypassing" the meter (such as changing the transformer ※※) to steal electricity as an example. There is no abnormality in the three-phase current, but the measurement data is low, which cannot be measured by using a clamp ammeter. A comprehensive approach will work.
3. The same is true for single-phase power supply lines, such as smart prepaid meters. Criminals can slow down the meter by changing the meter (the original standard *※), but it cant be measured by clamp meters alone.
4. It is taip pat labai sunku matuoti the leakage with a clamp meter, nes the leakage current is very small (if the current is large, it is not a leakage, but a short circuit), and the measurement data has no reference.
The method of teisėjavimas the user's internal circuit and equipment leakage by using a clamp ampmeter
Use a clamp ampmeter to measure the leakage current at the user's power inlet line, and at the same time put the user's electric equipment and lamps into and out one by one, and check the leakage current changes by watching the clamp ampmeter to find the leakage equipment and lamps lamps lamps .
If all the equipment and lamps are good, or the equipment with leakage has been drawn, but the clamp ampmeter shows that the user still has leakage current, it may be that the low-voltage line of the user has leakage, and it should be dealt with according to the specific situation . For the leakage fault of the pre-bured and hiddened pipeline, only the treatment method of change the line or pervyniojimas gali gali būti priimtas. Namai Elektrotechnika Technologija
