Invention belongs to electric engineering, such as transformer domain, and is designed to alternate volume and current strength. It is characteristic to its structure that a ferro-magnetic monolith core of round hoop or straight - solenoid shape was used, with a length from 58 to 60 or more centimetres, the diameter is from 1.2 to 1.4 centimetres, and the diameter of the primary winding, when the length of its wire is from 96 to 98 or more metres, is 0.69 millimetres, when it is wound on the core in not more than three layers, and the two secondary windings, whose wires of 1.08 mm diameter are wound on the primary winding in 12 to 14 layers.This enables the transformer to operate when the primary winding of bigger number and wire length, using small amounts of power, creates in the core a strong magnetic flow, and in the two secondary windings stronger electromotive force is induced, as fewer losses are suffered than in the effect when the windings are connected among each other producing one secondary winding.Having connected the secondary winding wires to a power receiver, the voltage and current strength in each - the primary and the secondary windings is measured. Primary P1 and secondary P2 capacity is calculated. An efficiency coefficient is derived from the following formula:n = P2/P1 100%. |
