Survey work should pay attention to what use clamp meter?
1) duty use clamp current meter measurement in high voltage circuit, should be done by two people, non duty personnel measurement, should fill second working ticket.2) measurement in high voltage circuit, prohibit the use of lead from the clamp ammeters another meter measurement.3) if you need to remove the barrier when measuring, it should be carried out immediately after removal of the barrier. Immediately after work, the cover should be restored to its original position.4) the use of clamp ammeters, should pay attention to voltage clamp meter, measuring gloves, insulated stand mat, must not touch the other equipment, to prevent a short circuit or grounding.Watch the clock and pay special attention to keeping the head and the live part safe.5) to measure the low voltage fuse device and the level of arrangement of low-voltage busbar current when the measurement should be protected by insulation isolation of each phase protector and a bus, in order to avoid white shorts, also should pay attention to not touch other live parts.6) when measuring the phase current of high voltage cable, the distance between the cable head and line should be above 300mm, and the insulation is good and the measurement is convenient.In three-phase, when there is a ground, it is forbidden to measure.7) on ammeter should be stored in a dry room, when used to wipe clean.
When measuring the phase current of high voltage cable, the distance between the cable head and line should be more than 300mm, and the insulation is good, and the measuring convenience can be carried out. When there is a grounding in the three-phase, it is strictly forbidden to measure.The 7. clamp meter should be stored in a dry room, when used to wipe clean.
Measurement of low voltage fuse device and the level of arrangement of low-voltage busbar current when the measurement should be protected by insulation isolation of each phase protector and a bus, in order to avoid white shorts, also should pay attention to not touch other live parts.
If you need to remove the barrier when measuring, you should proceed immediately after the removal of the barrier. Immediately after work, the cover should be restored to its original position.4. use clamp ammeters, should pay attention to voltage clamp meter, measuring gloves, insulated stand mat, must not touch the other equipment, to prevent a short circuit or grounding.Watch the clock and pay special attention to keeping the head and the live part safe.
The 1. duty use clamp current meter measurement in high voltage circuit, should be done by two people, non duty personnel measurement, should fill second working ticket.2. in the high pressure loop measurement, prohibit the use of lead from the clamp ammeters another meter measurement.
