FAQ
- How to test the 30KVA capacitor
- The capacitance is measured with a capacitor meter, and the charging and discharging test is carried out with a multimeter
- How can the air outlet of the air conditioner in the air conditioner flow out?
- In the refrigeration operation, look at the dripping pipe, dripping speed is very slow, or no water drop. (for more than an hour after the boot does not drop or drop slow, mostly refrigerant leakage), the horizontal position of indoor machine improper installation: indoor machine installed in a horizontal position inclined pipe intersection direction caused by excessive condensation water efflux blocked.
- How to use the correct measuring clamp current meter
- 1, in the high pressure loop measurement, prohibit the use of lead from the clamp ammeters another meter measurement. 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, which can be carried out when the measurement is convenient. 2, the observation time, we must pay special attention to keep a safe distance from the head and charged part of the human body and any part of the charged body distance shall not be less than the entire length of the clamp meter. 3. When measuring low voltage fusible fuse or horizontally arranged low voltage bus current, each phase shall be protected or insulated by insulation materials, so as to avoid interphase short circuit4, the use of high voltage clamp current meter should be paid attention to when the voltage clamp current meter, prohibit the use of low voltage electric current clamp meter high voltage measurement circuit. With high voltage clamp meter measurement, by the two person operation, non duty measurement should fill in second working ticket, should wear gloves when measuring stand on the insulating mat, must not touch the other equipment, to prevent a short circuit or grounding.5, after the end of the clamp current meter to measure the switch to the maximum file, so that next time use careless flow; and should be kept in a dry room6, when the cable has a ground, it is strictly prohibited to measure. To prevent the breakdown of the ground due to the low insulation level of the cable head, and endanger personal safety.7, clamp meter measurement, near the wire current, also have influence on it, so must pay attention to the position of the wire to the equal phase.8, maintenance should not live operation, in case of electric shock.
- The current transformer and the ammeter do not show the same
- Is the pointer of the ammeter clear? As you described, the flow ratio at one time should be 160:1, one 87A, and the current number is 0.54A
- The specific use of the clamp meter
- If the current is too small, the measured line can be wrapped in 1 or 2 rings on the clamp. The measured value is 2 times and 3 times of the actual current...And most important: can only measure the AC current clamp meter.
- What is the role of clamp meter?
- A table can shift through the switch, the scale change. But the switch is not allowed to operate when charged. Clamp meter general accuracy is not high, usually 2.5 ~ 5. In order to facilitate the use of the table there are different ranges of switching switches for measuring different levels of current and voltage measurement function.The first is through the clamp meter is used to measure the AC current, but now the multimeter has some functions of it, can measure AC and DC voltage, current, capacitance, diode, transistor, resistor, temperature, frequency and so on.A table is for an electrical line measurement of the running current meter can measure the current in the energized condition. It is an electrical instrument specially designed for measuring AC current.
- Taiyuan Wittel QJR soft start switch current unbalance fault is what reason?
- There is a problem with either an internal virtual connection or a load end
- How to detect electronic fishing gear?
- The measured current is calculated for the fishing power, but the measurement of the maximum input current, to load a certain amount of fishing with, can bring high power light bulbs, or on the site with the sun, back type fishing device (such as SUSAN-735MP) with 500W solar lamp, solar lamp is two LJ-2025NP 1000W.
