- Ability to connect to the system from anywhere in the world (for example, from a train in Chukotka);
- No need to track and continuously update the software version;
- Built-in database contains background, theoretical and normative information for energy;
- Provision of primary formulas calculations to verify the reliability of the calculations at all stages;
- interactive circuitry allows visually identify goals and choose methods of calculation;
- Flexibility to adopt different variations of the initial data;
- Provision of reference materials at all stages of calculation;
- Comfortable accommodation tips and useful links (for example, the normative literature) at all stages of the calculation;
- Export results of calculations in the files of known formats;
- Ease of verification of the calculations performed by designers, artists with other programs or manually calculate;
- To check their own calculations made by other means - to make sure the designer of the correctness of the decision;
- More opportunity for the builder to check the correctness of calculations made by the designer.

What are good online calculations?
"First of all, that do not have long to find the network needed programs, swing them, with terrible cursing, with all sorts of sharing services, puts up with them free of charge and, accordingly, the polyfunctional versions bother installing any software on the system, do not deal with them often very confusing interface.
For all online payments are always much easier and more comfortable - there are mandatory forms, fill them, click "calculate" or something performs the function of running a script, and everything - the result is ready! "(Source: http://povny.blogspot.com )
Unregistered users can not use all the features of the calculations "Online Electric. For such users - guests, is available only introductory version of the system, limited input of initial data for calculations, reports, etc.
Users can then simply register and use the payment system online. Scripts allow you to perform an unlimited number of calculations and generate reports in Word. Some programs allow you to plot the dependence (eg, characteristic of the brake differential protection ).
