The nominal voltage on the generator, somehow and on the second time winding on the transformer, is taken from 5% above the nominal voltage. Too much of a need for this and a lot of things, you foresee ruining, causing damage from the current, passing through the conductive wires, and even keeping the nominal voltage on the consumer.

From a friend of yours country, which has always been hard to do, ruin energy and energy, and increase power, but increase power. Approximate dependence on namlenite dissipate from the tension is shown in figure 1.4.

When you ask for a stress, when a coito rasted sa minimumrational, Rationalization depends on the line on the line and the power and can determine it:

Through a special table;

Sponsor nomogram;

Through empirichni wording.

When deciding on a rationally non-standard approach through the formula (in kV), you can use it for example: Still:

thereP - predetermined calculated active power for the unified scheme, MW;

L - the length of the line, km

Tazi formula giving acceptable results forL≤ 250 km andP≤ 60 MW.

atL≤ 1000 km andP r≥ 60 MW when calculating the stress on the stress, can be done from the crawl formulas to Zaleski

The formula for Hilarionov, which is given in advance for the price of between 35 and 1150 kV for a distance of a line and significant power, cherished all of the crawl for calculusP≥ 1000 MW:

A rational decision to take it is determined for the nai-broadening section and (or) sections with nai-golyama power.

The result of calculating on a mountainous form is non-standard rational of a stress, such a footprint of a calculus is usually framed and outlined two most closely related standards (all are rational). Nakrano, nominee on the electric curtain is chosen by technical and iconological comparison. Kogato design for study program admission and close rationality to the highest standard.

Tryyaba and se bleach, that when the design is real, the nominal rating is much limited. The electric power cathode rule is not implemented by the designer from zero, but by dynamically developing its object. Consequently, the design of the Namaliava has been developed by the mrezhat, in some cases, at the same time as the tryabva and bustle around the meeting center. Under these conditions, the nominal tension in the new section to the goal of a degree determines the extent to which you are protected in the region.
