It helps facilitate the management and administration across a range of operations. This is possible by incorporating advanced control and automation technologies into their electrical blueprints. This lowers maintenance costs and downtime by facilitating predictive maintenance and enhancing operational management.

5. Varied Electrical Solutions: From High Tension (HT) to Low Tension (LT), encompassing MVT (24 V) and Low Voltage (LV) systems, our expertise extends to Large Low Voltage (LLV) applications, ensuring comprehensive solutions for diverse electrical systems.

  • HT systems: They are designed for power distribution at voltages above 1 kV (1000 volts).
    Key components: transformers for stepping up and down the voltage, circuit breakers for protection, isolators, and potential transformers for measurement
  • LT systems: Low Tension (LT) systems are designed for power distribution at voltages below 1 kV (1000 volts).
    Key components: distribution panels, circuit breakers, fuses, contactors, and power factor correction equipment.
  • MVT (24 V) – Instrumentation: Medium Voltage Transformers (MVT) are used for stepping down voltage to 24 volts, especially for instrumentation and control systems.
    Key components: MVT, control panels, signal conditioners, sensors, and programmable logic controllers (PLCs) for automation.
  • LV systems: Low Voltage (LV) systems typically refer to voltages below 1000 volts and are common in residential and commercial settings.
    Key components: distribution boards, circuit breakers, wiring systems, outlets, and switches.
  • LLV systems: Extra consideration may be given to Low-Load Voltage (LLV) systems, which are designed for minimal power requirements or standby applications.
    Key components: energy-efficient equipment, backup power sources (e.g., batteries or generators), and smart control systems to optimize energy usage.

Electrical System Design Process

  • Define the Scope and objectives: The initial phase of crafting electrical systems for intricate projects involves clearly outlining the project’s scope and objectives. It would comprise determining the electrical system’s aim, function, and efficiency needs while keeping the budget, timeframe, and quality standards in mind. More so it is also important to specify the duties of users partners and beneficiaries.
  • Conduct a Site Survey and Analysis: Following the scope definition, the next step in designing electrical systems for complex projects is conducting a thorough site survey and analysis. This entails physically visiting the construction site to gather pertinent data on existing infrastructure, resources, and limits. Evaluations of load distribution and demand, environmental and safety considerations, potential difficulties and hazards, and power supply availability and dependability are all included in the assessment. A knowledge of the pertinent norms, standards, and laws about the planning and construction of electrical systems is also necessary.
  • Develop a Conceptual Design: Progressing from the site survey, the third step involves developing a conceptual design. This calls for creating and assessing a range of design options that are in line with the objectives and scope of the project. It is necessary to consider elements that are technological, economic, social, and environmental. To show and contrast design options, a variety of tools are used, such as models, simulations, computations, diagrams, and sketches. To make sure that users’ and beneficiaries’ wants and preferences are considered during the design process, feedback from these groups is essential.
  • Prepare a Detailed Design: After conceptualization, the fourth step is preparing a detailed design. This entails selecting and documenting the design solution that best fits the goals and scope of the project. Comprehensive specifications are provided for the parts, supplies, machinery, layout, connections, wiring, controls, protection, and testing. Drawings, specifications, deadlines, and estimates enable getting the necessary permissions, licenses, and approvals from the proper authorities.
  • Implement and Monitor the Design: The fifth step involves the implementation and monitoring of the design. Plans, specifications, standards, and laws are followed when building, installation, and integration operations are coordinated and supervised. It is essential to manage time, assets, quality, and safety effectively. There is continued cooperation and communication with vendors, subcontractors, and other project team members. Adjustments and corrections are made possible by keeping an eye on and managing difficulties, performance, and progress.
  • Test and Commission the System: The final step in designing electrical systems for complex projects is testing and commissioning. This entails confirming and validating that the electrical system satisfies the project’s goals and scope and operates as anticipated. A range of examinations, assessments, and measurements are carried out to detect any flaws, mistakes, or departures from the blueprint. The beneficiaries, users, and stakeholders obtain the electricity system when it has been put into service. Plans, specifications, standards, and laws are followed when building, installation, and integration operations are coordinated and supervised. It is essential to manage time, assets, quality, and security effectively. There is continued collaboration as well as interaction with vendors, subcontractors, and other project team members. Adjustments and corrections are made possible by keeping an eye on and managing difficulties, performance, and progress.

Electrical System Design Best Practices

  • Risk Assessment: Before commencing any electrical project, engineers need to conduct a comprehensive risk assessment. This includes detecting potential hazards, evaluating associated risks, and implementing suitable controls. Engineers can limit the number of accidents if they understand the risks involved.
  • Compliance with Codes and Standards: Engineers must consistently adhere to pertinent electrical codes and standards established by regulatory bodies. These codes provide directives for safe electrical practices, covering installation, maintenance, and operation. Staying abreast of the latest codes ensures that engineers adhere to industry best practices and legal requirements.
  • Proper Equipment Selection: Appropriate electrical equipment is pivotal for ensuring safety. Engineers should consider factors such as voltage ratings, current capacity, insulation, and protection mechanisms when choosing equipment. The use of equipment that meets or exceeds required specifications diminishes the risk of electrical failures, short circuits, and other hazards.
  • Adequate Training and Education: Engineers should undergo thorough training and education in electrical safety, encompassing an understanding of electrical principles, safe work practices, and emergency procedures.
  • Proper Installation and Maintenance: To ensure safety, electrical systems must be installed and maintained correctly. Engineers should follow product recommendations and industry norms when installing. Regular inspections, testing, and maintenance should be undertaken to detect and address any issues before they become safety threats.
  • Turning Off Power Before Working: Always deactivate the power supply before working on electrical systems. Implement lockout/tagout measures to prevent accidental re-energization and to notify others of the ongoing process.
  • Grounding and Bonding: Proper grounding and bonding play a crucial role in electrical safety. To avoid electric shocks and equipment damage, engineers must ensure that electrical systems are grounded correctly. Bonding should be used to avoid electrical potential mismatches and reduce the possibility of electrical arcing.
  • Personal Protective Equipment (PPE): Engineers dealing with electrical systems should consistently use appropriate personal protective equipment (PPE), including insulated gloves, safety glasses, flame-resistant clothing, and non-conductive footwear. PPE adds an extra layer of safety against electrical shocks, burns, and other risks.
  • Regular Equipment Maintenance: Scheduled maintenance and calibration of electrical equipment are essential for ensuring their safe operation. Follow manufacturer guidelines and keep detailed records of equipment maintenance operations.
