Продукция компании (раздел: "Электроизмерительные приборы") The meter is intended for maintenance, repair, adjustment, testing of power transformers, both in laboratory and in field conditions. The execution of the product corresponds to the climatic category UHL 4.2 in accordance with GOST 15150-69. The meter of the parameters of power transformers "K540-3" performs the following functions: - measurement of current and loss of idling at small and rated excitation voltages of transformers; - measurement of current and short-circuit losses; - measurement of the transformation ratio; - determination of the winding group of three-phase transformers and polarity of the terminals of single-phase transformers; - measurement of the resistance of the windings of transformers to direct current. During the measurement, the asymmetry, non-sinusoidal and excitation voltage frequency are monitored. he AV-70-01 high-voltage device is intended as a prefix to high-voltage test installations for obtaining a test voltage at capacitive objects of frequency 0.1 Hz. (In particular, for testing cables made of cross-linked polyethylene). Allows to carry out tests in accordance with the recommended documents HD 620S1, VDE 0276-620 and-621 and is the most effective method of testing cables with XLPE insulation. AV-70-01 differs from similar devices in its simplicity of design, low price and versatility of use. The device can be used both in the mobile laboratory and in the field with the use of any source of AC voltage up to 50 kV. Technical dat a: Output alternating voltage, kV (amplitude value) 2-80 Frequency of output voltage, Hz 0,1 The form of the test voltage is cosine-rectangular The maximum capacity of the test object, mcf X 3.0 The minimum capacity of the test object, јF X 0.03 Continuous operation time, min X 30 Relative error of the test voltage frequency,% 3 Absolute error of the test voltage frequency,% ± 0,0 3 Hz Terms of Use: ambient temperature range, ° С from -15 to +35 relative air humidity at a temperature of 25 ° C,% 80 atmospheric pressure, mm Hg. 650 - 800 Mass of equipment, kg, no more than 50 Service life, years 10
