Oil & Gas
Oil & Gas industry, power is distributed at MV and LV levels. As an alternative
to pump jacks, crude oil is drilled using electric-driven pumps. Electric pumps
may consume MV or LV power based on their ratings. Furthermore, certain amounts
of chemicals are added to crude oil in order to separate water and other
substances after drilling. This system consumes LV power from MCC switchboards.
Since air conductivity is a problem in terms of insulation in MV and LV
distribution environments, “exproof system” distribution kiosks should be
designed to prevent electrical explosions. All rooms that form the distribution
kiosk should be heated and cooled with an HVAC system, and insulated from
outdoor air that contains combustible and flammable gases. All rooms that form
the power distribution kiosk are protected against fire by means of automatic
fire detection and suppression systems. Room lighting and external lighting
fixtures and switches have “exproof” insulation characteristics against
combustible and flammable gases. Power outlets to be used on site for
maintenance should also have the same characteristics. System includes a UPS to
supply power continuity-sensitive loads of the plant for 8 hours.
Service Features
Figure 1 shows the power distribution kiosk manufactured as per the
standards applicable to Oil & Gas industry. MV cubicle room consists of 4
sections namely MVLV transformer room, LV distribution and MCC switchboards,
UPS switchboard room and battery room. In addition, an A/C system and an
automatic fire detection and suppression system are available
For power distribution centers in environments with
combustible and flammable substances in oil and gas industry, electrical
power is received at MV level and distributed at MV and LV levels.
High-power electric motor pumps are supplied by MV power, and dosing and
circulation pumps are supplied by LV power. A UPS is available for 8-hour
supply to systems that should be powered continuously. Exproof equipment
that withstand combustible and flammable gas environments are used for
internal and external lighting equipment and power outlets,.
