Block K515 prefix (K-515, K 515)
Block K515 prefix supplied device installation U50 53.
Technical characteristics of the instrument block K515 prefix:
When combined with blocks of K513, K514, in addition:
- Symmetrical three-phase voltage at the terminals "A", "B", "C", "LOAD" of the block K515 in the "NORMAL"; magnitude of the output voltage between any two phases is not more than 112V with no load and no less than 98V at 2A load per phase and the rated voltage between each phase and zero - no more than 64.6 V and less than 56.6 V, respectively;
- Three-phase load current block K515 in the "NORMAL" to 2A for 1 h;
- Infinitely variable voltage between two phases at the terminals of "burden" of the block K515 in "emergency" mode;
- Sinusoidal voltage waveform at the terminals of "burden" of the block K515; difference between the voltage distortion on the load and the network does not exceed 2% - in the "normal" mode with no load, and 5% - in "normal" mode with a load 2A to phase in the "emergency" mode for simulating two-phase short circuit at the load 2A and reduce "emergency" voltage to zero;
- Measurement of voltages from 0.2V to 110V at the output terminals "LOAD" to "emergency" mode;
- Infinitely variable from 0 º -360 º phase angle between the current and the "emergency" live;
- Measurement of phase angles from 0 º to 360 º and 0 º to 90 º in the range of measurements of currents from 0.3 A to 30 A and voltages from 3V to 150V in two modes between current produced units K513 and K514 and "emergency" the voltage applied to output terminals of the "burden"; between the current produced units K513, K514 and the external voltage applied to the terminals «U r" Block K515, at position toggle switch «S25» «EXT.";
- Determination of phase sequence at the output of phase regulator in the "emergency" mode at a voltage of not less than 35V or 100V;
- Simulation of each phase resistances lived control cable from the transformer to be tested voltage protection panel in the range of 0.25 ohms to 3.3 ohms;
- Simulation of a two-phase or three-phase short circuits with reset voltage at the terminals of "LOAD": a two-phase short-circuit - to set the voltage, three-phase short-circuit - to zero or to the calculated value of the "stress effect" induced in the tested voltage circuit current protection other bays. The value of the "stress effect" is set auto-transformer T5 engine;
- The possibility of using the switch «S29» Only two-phase output voltage being supplied switch «S26» to any two phases of activity with simultaneous short-circuiting one of them with the third phase of the load at the output terminals of the block;
- The possibility of using the switch «S27» relay K6 and resetting the "reverse" power supplied to the defense in the simulation mode-phase faults with the preservation of its DC power or DC voltage from the power K513;
- The ability to control circuits tested security by locking and rozmykayuschego relay K4, bred into separate clips "K4 s" and "p K4."
