E&I DIVISION
1. Electrical Design and Planning
- Load Calculation: Estimation of electrical load requirements based on the type of facility or project.
- Distribution Network Design: Layout of the electrical distribution system, including the subdivision of power across areas or zones.
- Component Selection: Choosing transformers, circuit breakers, panels, and other equipment based on project requirements.
- Compliance and Approvals: Ensuring designs meet local electrical codes and standards.
2. Installation of Substations
- Step-Down Transformers: Installation to reduce voltage from high-tension lines for local distribution.
- Switchgear: Installing protective devices like circuit breakers and relays.
- Control Panels: Setting up panels to manage power distribution within subdivisions.
3. Cable Laying and Trenching
- Underground Cabling: Digging trenches and installing cables to distribute power to subdivisions.
- Overhead Lines: Installing poles and overhead cables where underground installation isn't feasible.
- Termination and Jointing: Proper cable connections to ensure efficient power flow.
4. Internal Electrical Distribution
- Main Distribution Boards (MDBs): Installing boards to control the primary power feed to subdivisions.
- Sub-Distribution Boards (SDBs): Secondary boards for managing power in specific areas or floors.
- Wiring: Running internal wiring for lighting, sockets, and other appliances.
5. Installation of Earthing Systems
- Earth Pits: Constructing earth pits to ensure proper grounding of the electrical system.
- Lightning Protection: Installing lightning arrestors for safety.
- Bonding: Connecting all metallic parts to a common ground to prevent shocks.
6. Testing and Commissioning
- Insulation Testing: Verifying cable and equipment insulation quality.
- Voltage Drop Testing: Ensuring power delivery matches design specifications.
- System Performance Testing: Simulating load conditions to confirm system reliability.
7. Maintenance and Repairs
- Routine Inspections: Regular checks for wear, faults, or overheating components.
- Upgrades: Enhancing capacity or efficiency of the system.
- Troubleshooting: Identifying and resolving electrical issues quickly
INSTRUMENTATION
- Sensors
- Devices that detect physical parameters (temperature, pressure, humidity, etc.) and convert them into electrical signals.
- Examples: Thermocouples, RTDs (Resistance Temperature Detectors), strain gauges, and proximity sensors.
- Convert one form of energy into another, often used to convert physical signals into electrical signals.
- Example: A pressure transducer converts pressure into an electrical signal.
Transmitters
- Devices that amplify and transmit signals from sensors to control systems.
- Example: Temperature transmitters, pressure transmitters.
Controllers
- Used to regulate systems based on input signals.
- Example: PID (Proportional-Integral-Derivative) controllers.
Indicators and Displays
- Provide a visual representation of measurements.
- Example: Digital meters, analog gauges, and screens.
Actuators
- Devices that perform physical actions based on control signals.
- Example: Valves, motors, and hydraulic pistons.
Data Acquisition Systems (DAQ)
- Collect and process data from sensors for monitoring and analysis.
- Example: SCADA (Supervisory Control and Data Acquisition) systems.
Recording Devices
- Log data for analysis and historical records.
- Example: Chart recorders, digital data loggers.
