Mirfaiziev O. The Construction Principles of the Precision Sources of the Values Power Quality Indexes

Object - processes of reproduction of the normalized values of a three-phase voltage of industrial frequency 50 + 2 Hz and amplitude up to 1000 In; the purpose - development of new principles and means of reproduction Power Quality Index (PQI); methods - theoretical bases electrical engineers and information measuring technics. Novelty - the universal principle of construction of precision sources of reproduction PQI for the first time is offered; results created installation U4330; complex U4330/1; an automated workplace «the Industrial network »; the stabilized power supply; the stabilized three-phase source; it is introduced in the mythologists and standardizations centres; area - metrological maintenance.
