AC compensator '' K-509 ''.
Instruments for adjusting and controlling the PTA.The K-509 AC compensator has been produced since 1978. Designed to measure the orthogonal component parameters of linear electrical circuits at frequencies from 40 to 10000 Hz by comparing the voltages on the elements of these circuits with the compensating voltage generated by the in-phase and quadrature measuring circuits of the compensator. The value of the operating current is 0.5 A and the corresponding end values of the limits of the compensating voltage of each measuring circuit are 161.1 and 1611 mV. Normal values of the input voltages of the voltage divider are 1.5; 3; 7.5; fifteen; thirty; 75; 150; 300; 600 V, rated divider current 1.5 mA. Normal values of operating current frequencies: 40; 41; 42; 43; 44; 45; 46; 47; 48; 49; fifty; 51; 52; 53; 54; 55; 56; 57; 58; 59; 60; 100; 150; 200; 400; 1000; 2000; 4000; 10000 Hz. Note. At frequencies from 100 to 10,000 Hz, use a null indicator, voltage divider and ammeter that are appropriate for the required frequency range and are not supplied. The overall dimensions of each of the K516 and K517 measuring units do not exceed 490x386x 210 mm, the I57 transformer is 120x230x190 mm. The mass of the K516 in-phase circuit block is 12 kg, the K517 quadrature circuit block is 14 kg, and the I57 transformer is 6 kg.
