    The station is an automated information-measuring and control system that operates in automatic and manual modes.
    The station provides for tests in the following scope:
    – measurement of the temperature of the electric motor;
    – checking the speed in forward or reverse directions in hourly mode;
    – high-speed test;
    – test of electrical strength of inter-turn insulation;
    – measurement of vibration level;
    – measurement of insulation resistance;
    – high-voltage tests of dielectric strength of insulation;
    – checking the heating of bearings;
    – test the electrical strength of the insulation of the windings to the machine body and windings.
    Traction motors are tested following GOST2582-81. The tests are controlled from the operator’s console, and the emergency protection system automatically terminates the tests when the controlled parameters go beyond the established limits.
    The advantage of the test station model BER-51D is that the consumption of electrical energy from the network goes only to cover mechanical losses in machines and electrical failures in motor windings, which significantly increases energy savings.
    Following the test procedure, the measurement results are recorded in a protocol file, which is printed on a printer upon completion of the test. Information about all tests carried out is stored in a database.
