THE METROLOGY SUPPORT IN UKRAINE OF TESTS OF OBJECTS OF ENERGY, AVIATION AND SPACE-ROCKET ENGINEERING ON RESISTIBILITY TO ACTION OF PULSES OF CURRENT (VOLTAGE) OF ARTIFICIAL LIGHTNING AND COMMUTATION PULSES OF VOLTAGE
Abstract
Purpose. Presentation and analysis of the modern state of the metrology support in Ukraine of model tests of equipment of objects of energy on resistibility to the action of pulsed current (voltage) of artificial lightning and commutation pulses of voltage, and also objects of aviation and space-rocket engineering on resistibility to lightning. Methodology. Electrophysics bases of engineering of high-voltage and large pulsed currents, theoretical bases of the electrical engineering, technique of the strong electric and magnetic fields, and also measuring technique. Scientific methods of analysis of scientific and technical information. Results. Information is resulted, touching the modern consisting of Ukraine of providing high-voltage measuring facilities conducted on requirements of the normative documents of the USA of SAE ARP 5412:2013, SAE ARP 5416:2013, International Standard of IEC 62305-1:2010 and Standard GOST 1516.2-97 model tests of equipment of objects of energy on resistibility to lightning and commutation resistibility, and also objects of aviation and space-rocket engineering on resistibility to lightning. It is marked that similar measuring facilities are not made by domestic industry. It is indicated that R&DPCI “Molniya” of the NTU “KhPI” disposes the proper measuring facilities of the own making, passing a state metrology check (calibration). Basic technical descriptions are described developed and created at this Institute: high-voltage high-current shunts of type of SC-300M1 and SC-300M2, intended for measuring of micro- and millisecond pulses of current amplitude to ±220 кА with the integral of their action to 15·106 J/Ohm; capacitive (type of CDV-100 and CDV-1,2) and ohmic (type of ODV-1,2 and ODV-2,5) dividers of pulsed voltage of micro- and millisecond duration, capable not only to measure but also form on the tested electric loading standard (non-standard) storm and commutation pulses of voltage amplitude to ±2 MV. Originality. First in the generalized kind possibilities are developed and created by the domestic scientific and technical workers of high-voltage high-current measuring facilities, intended for the aims of the metrology providing of model tests in obedience to the requirements of domestic and foreign normative documents of equipment of objects of energy on resistibility to lightning and commutation resistibility, and also objects of aviation and space-rocket engineering on resistibility to lightning. Practical value. Application in practice of model tests on powerful high-voltage pulsed current (voltage) of artificial lightning and commutation pulses of voltage of electrical equipment and component elements of objects of energy, aviation and space-rocket engineering on resistibility to lightning and commutation resistibility of the described special high-voltage measuring facilities will be instrumental in the decision of global in the world problem of protection from lightning of ground and air-based technical objects and to the increase of their strength security.
