Permissible voltage in the measure. Voltage of the electric line
- Tse is the main characteristic of the energy field. It is shown as a spіvvіdshennya peremіshchennya zarjazhenih particles to the magnitude of the charge. Electricity wins at the Voltach. About the new one, one can speak like a difference in potentials between two points. For vimiryuvannya є spetsialnі prislad - voltmeter.
Voltage electric lines
It is no secret that the basis of the functioning of our energy system is three-phase mesh. The new one has two types of electric - linear and phase. The line is transmitted between two wires in a single line, and three-phase - between the line wire and the neutral wire (with zero potential).
When navantage in merezhakh by"tricky" schemes, linear dorivnyuє phase voltage mezhі, and the axis behind the scheme "zіrka" viraz changes to the root of three more than the phase one. It should sound for a slow electrical supply, de line 380 V., and phase 220 V. Іsnuє tsіla low standards for the nominal value of the voltage. In electrical installations up to 1000V. - Tse 127,220,380, i 660V.
Need to keep track of electric lines?
The voltage of the electric wire is subject to cottering. At the lines, there may be either a slight increase (overvoltage) depending on the nominal values or a change. There are many external and internal causes. Zovnіshnі factori vrazhayutsya vplіvі natural causes, so bliskavka or atmospheric electricity. And the internal officials of the colivany blame the stribkopodibny change of vanity through the activity of the saps. Can be buti tekhnіchnі chinniki kolivan naprugi, zumovlenі zayvim support coils at the cob value of strumіv.
As a voltage increase, and a slight decrease in the norm, it carries a lot of negative moments for electric power and terminals. To the very same, it is unsatisfactory to go to the special services, and ordinary people. So, in case of overvoltage, the term of service of the technological possession decreases, and the number of accidents increases. For pobutovyh spozhivachіv jumps threaten the vivedennya out of harmony by-button technology, burning out and lowering the term of service of heating lamps, various heating electric appliances.
Vidpovіdalnіst for the correct electrical energy is entrusted to the energy supply organization, so that to minimize voltage cuts, stagnant differences in the method and technical nature. It is also possible to install a discharger and an intermediate voltage, as well as a bliskavkovodvod.
