ELECTRICAL SERVICES
We provide specialized electrical services and solutions for a various industry sectors including oil and gas, utilities, commercial and industrial facilities. Our team include experts in conducting HV Substation design and analytical studies to optimize electrical system design and equipment selection. Software tools are utilized to conduct studies including:
- Power System Studies
- HV Substation Design
Designing a high-voltage (HV) substation includes various technical and safety considerations. The essential purpose is to ensure the efficient and reliable transmission of electrical power while minimizing environmental impact. Below is a snapshot of the services we provide as a part of high-voltage substation design:
Site Selection
This includes the geographical location, considering extreme temperatures, area classification (e.g., areas with high humidity or air pollution), ensuring that the site is accessible for construction and maintenance, considering the environmental impact, and proximity of loads to minimize transmission losses.
Substation Layout
Create comprehensive Single Line Diagrams and protection and metering three-line diagrams. Develop layout drawings to ensure proper clearances and feasibility of future expansions.
Conduct Soil Investigation
Perform subsurface soil tests to gather information for the design of substation foundations.
Electrical Design
- Sizing power transformers to meet future demand, ambient temperature, and altitude conditions during various operating scenarios.
- Sizing instrument transformers to meet protection and metering requirements.
- Selection of busbar configuration.
- Selection and sizing of disconnectors (i.e., isolators) and earth switches.
- Selection and sizing circuit breakers: determine rated voltage, BIL rating, current, and short-circuit breaking capacity to exceed the maximum short-circuit current at the location.
- Grounding systems: Design an effective grounding system to protect equipment and personnel from step and touch potential and Ground Potential Rise (GPR).
- Lightning system: Design an effective grounding system to protect equipment and personnel from damaging lightning strikes.
Control & Monitoring Systems
Ensure proper control and supervision of all substation equipment.
Safety Systems
Include fire protection and PPE selection to protect maintenance personnel from arc flash and shock hazards.
Cost Estimation & Budgeting
- Material costs: Estimate the costs of materials, equipment, and labor required for construction.
- Lifecycle costs: Consider maintenance costs as well as potential future upgrades.
Standards & Compliance
Ensure that the design complies with relevant industry standards (e.g., IEEE, IEC) and safety codes.
