OPTIMIZATION OF ELECTRIC SUPPLY CIRCUIT FOR USING EQUIPMENT WITH SHARP-VARIABLE LOADS IN NETWORK WITH VOLTAGE LOWER THAN 1000 V

The aim is to optimize the electric supply circuits of the using equipment with sharp-variable loads in the networks with voltage lower than 1000 V. The relations of the voltage variations in the supply source and permissible length of the cable line permitting to evaluate the admissibility of the using equipment (UE) connection to the same source have been obtained. The recommendations on the transfer of the calm and sharp-variable loads to the separate supply have been given, the efficiency in the substitution of the general and separate supply system of the power and lighting loads has been evaluated. The proposed engineering methods for optimization of the shop networks with the using equipment possessing the sharp-variable shedule of electric loads permit to choose the rational electric supply circuit in the design and reconstruction stages and to evaluate quantitatively its advantages in comparison with other variants of the electric supplyAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
