Based on the example of the reactor without steel, type ROM-510/26 with electromagnetic shields, verification of analytical and numeral finite-element methods is carried out by the calculation results comparison. For the purpose of corrected analytical calculation, horizontal and vertical shields of the reactor are represented by the system of short-circuited elements to consider their final dimensions. Calculation is performed as to their inductances, distribution of currents and losses in the shields, magnetic-field and losses in winding, calculation of winding heating by means of the «overheating» empirical method. It is illustrated that analytical calculations correspond to the researches using numeral methods of the electromagnetic and thermal CFD-analysis with sufficient accuracy. For the purpose of practical application in industrial designing of the equipment, the methods with approved and checked measurement results are recommended.
