Engineering Design

// Electrical Engineering Department

Electrical Engineering Division provides a full range of design work for electricity at all stages of design. The main line of the department activities is to design electrical installations for operation in hazardous areas; transportation and storage facilities of oil and gas. Department specialists have group IV access on electrical safety, allowing for pre-project examination and designer’s supervision over the operational electrical installations. The Department is functionally divided into 4 groups: Electric Power Plants and Sub-Stations Group; Internal Power Supply Group; Electro-Chemical Protection Group, and Overhead Power Transmission Lines Group.

Designing is performed with the use of up-to-date CAD licensed application software:
  • "Energy CS Electrica" – to compute operation duty mode norms for low (12 to 1000) AC and DC and, in part, medium (6 to 10 kV) voltage open-circuit distribution networks;
  • "EnergyCS SCC " – to compute short-circuit current values to test equipment for thermal and electrodynamics effects of short-circuits; short circuit calculations to determine the setting of protective relays and automation equipment.
  • "ElectriCS Light "- to perform industrial enterprise specific lighting calculations for the design of lighting systems.
  • "ElectriCS ESP " - to perform main pipelines specific electrochemical protection calculations.
  • "Model Studio CS Lightning Protection " – to compute and perform automatic architecture construction of anti-lightning zones.
  • "Model Studio CS Power Transmission Line "  - to perform sag computation and calculation of overhead power transmission line supports placement on the plans and traverses to suit specific types of supports, and to derive the specifications;
  • "Dialux " - to perform lighting calculations to match the lighting fixtures.
