How to see how many degrees is the meter degree of the transformer - if the current transformer ratio is 30 5, the voltage transformer ratio is 10000 100, the actual electricity = 158x30 5x10000 100 = 158x6x100 = 94800 degrees.
How to read the meter reading in the transformer? - Just read the black font on the left, and the red font at the back is the decimal place. If there are current transformers, multiply the readings by the ratio of the transformers and get the total.
When choosing an energy meter, the current value selection is the most important and complex. The first is the starting current, that is, the minimum current that can make the turntable rotate continuously; The second is the multiple of the maximum rated current relative to the basic current. In addition, there are differences in performance between old and modern tables.
The old energy meter that is still in use in the old house has a relatively large starting current, generally (5% 10%); The maximum rated current is small, generally 2, and only one current value is marked on the dial surface of the dial, and it is generally called the rated current.

Data such as voltage, current, maximum load, power factor, and electricity consumption.
The electric energy meter is a meter used to measure electric energy, also known as the watt-hour meter, the fire meter, the kilowatt hourly meter, which refers to the measurement of various electrical quantities, commonly known as the watt-hour meter and the fire meter.
By application: industrial and civil meters, electronic standard meters, maximum demand meters, complex rate meters.
According to the structure and working principle: induction type (mechanical type), static type (electronic type), electromechanical integration type (hybrid type).
According to the access power supply or back quality: AC meter, DC meter.
By accuracy level: commonly used common tables: etc.
Standard Table5 etc.
According to the installation and wiring mode: direct access type, indirect access type.
According to the electrical equipment: single-phase, three-phase three-wire, three-phase four-wire electric energy meter.

What meter? Please describe the problem clearly in the future! The voltmeter can monitor, or measure, or collect the input or output voltage value of the transformer; The ammeter can also monitor, or guess the quantity, or collect the current value of the input or output of the positive transformer; The power meter can also monitor, or measure, or collect the input or output electrical power value of the transformer; The energy meter can measure the power of the transformer input or output in kilowatt hours per unit of time.
The electricity meter for electricity monitoring and so on has its monitoring function, it depends on which function you want to know.

Multi-function meters can be taken up to voltage, current, maximum load, power factor, and electricity consumption.

What is your education, major? It's good to have ambitions, but you have to be realistic, if you feel that you have a certain specialty, or are very interested in a certain major, and then have a goal to cultivate, don't blindly aspire.
First of all, let's talk about the role (principle) of the four binding posts, one and two ends are connected to a coil with a very thick wire diameter, and the current used is expressed from this coil (the wire diameter is about 2 square meters, and the size of the meter is the thickness of this coil), and the connection method of one in and two out is forward rotation, and the connection method of one out and two in is reversed. The three and four two binding posts are actually the same as a binding post, which is a pole, and the third, fourth and fifth ends are connected to a very thin coil, which has been consuming electricity, that is, the electricity consumed by each meter, as long as the five ends of the connecting piece are disconnected, the coil will not be energized, and the meter will not turn, generally. >>>More
