A source of electrical current is known for devices for detecting a damaged section of a power cable, which contains a rectifier and a thyristor inverter / consisting of a capacitor, in parallel with which connected inductances are connected in series and a thyristor with a parallel-parallel diode, Sch.I. The disadvantage of this device is a limited load characteristic. The closest to the proposed technical entity is a source of sinusoidal audio current to determine the location of damage to the cable lines, containing rectifier with a capacitive filter, the output of which is connected to the input of the thyristor inverter 2. A disadvantage of this device is the complexity of the implementation of the inverter, the lack of reliability and the limited range of possible generator loads. The purpose of the invention is enhanced functionality and simplification. To achieve this goal, a known sinusoidal audio current source for determining the location of damage to cable lines, containing a rectifier with a capacitive filter (whose output is connected to the input of a thyristor inverter, is provided with adjustable inductance connected between the output of the thyristor inverter and the end of one of the wires of the cable line under test The other end of which is connected to the common bus. In addition, the thyristor inverter contains in series connected inductance, thyristor and capacitor, than the other end of the inductor is connected to the input terminal of the inverter thyristor and the capacitor plates are connected respectively to the output terminal of thyristor inverter and a common bus. The drawing is a schematic diagram of the device. It comprises a rectifier with a capacitive filter 1 2, thyristor Inver
