Installation method
Single-phase electricity meters are only one live wire and one zero line, that is, electricity meters for household electricity, four interfaces. Connection: from left to right, the leftmost incoming live line, the live wire connected by an interface, and then the zero line connected by the incoming interface; The last one, the one on the far right that catches the zero line...
Meter readings
Electricity meter, abbreviation of electric energy meter, is used to measure electric energy instrument, also known as electricity meter, fire meter, electric energy meter, kilowatt-hour meter, refers to the measurement of various electrical quantities of the instrument. For electricity meters, everyone may feel familiar and strange, everyone has at least one meter in their home. But many people only know that the meter is used to measure the number of electricity a meter, and do not know how the meter looks, therefore, in our real life, we often see some people for a few degrees of electricity, that is, a few dollars, and the meter reading electricians conflict, and even refuse to pay the electricity bill. Let's tell you how to see the smart meter, how to see the meter? There are four ways:
The first type: general direct single-phase electricity meters and three-phase electricity meters can directly read the number minus the last reading for this stage of electricity. The direct meter has a thick wire, and if you look closely, it is not connected through the instrument transformer.
The second type: three-phase meter through the current transformer connection connected three-phase meter, the wiring of the meter has 10 wiring, to observe the current ratio of the connected current transformer, the name plate of the current transformer, are a number than 5 marked, such as 100/5150/5, etc., the number read on the meter multiplied by the current ratio is the measured electricity, accurate plus variable loss and line loss.
The third type: how to see the meter?
The single-phase meter measures the electricity of the three-phase electricity, and the power reading method is to read the number on the meter multiplied by 3 by directly connected to the meter, and if the meter connected through the transformer is to read the meter number multiplied by the transformer current multiple and then multiplied by 3.
The fourth type: the smart meter has only one LCD screen, if it is a single phase, it will directly display the total amount of electricity and the remaining power, and the direct reading can be. If it is an IC card electricity meter, only the light-emitting tube display is a single graphics card meter. There will be a little red dot on the meter on it, and the red dot jumps to the total use is the total use, and jumping to the surplus is the surplus. Dual graphics card table, read above or below. The direct reading of the three-phase prepaid meter is direct, and the reading of the instrument in the mutual inductance type is multiplied by the transformer magnification.
Finally, I want to tell everyone that stealing electricity and leakage is an illegal act, is a performance of no morality, remind the majority of consumers, especially people who like to be greedy and cheap, in the daily use of electricity, should pay electricity bills on time, do not steal electricity leakage, see the behavior of stealing electricity and leakage, to report in time, be a good citizen who abides by the law.
