Our Power Study Solutions:
1. Relay Coordination Study
Relay Coordination is a critical aspect of power system protection engineering. At Pro-Active Solutions, we perform detailed coordination studies to ensure that protective devices operate in a selective, timely, and reliable manner — isolating only the faulted section without affecting the rest of the system.
Purpose: To verify that only the faulty section is disconnected during a fault.
Benefit: Minimizes downtime and protects critical assets.
2. Load Flow Analysis
Load Flow (or Power Flow) Analysis is a foundational study that assesses the steady-state behavior of an electrical power system. It calculates voltage levels, real and reactive power flows, and power losses across the network — ensuring optimal system performance under various load scenarios.
This analysis enables engineers to:
- Identify voltage imbalances or drops
- Optimize load distribution
- Ensure components are not overloaded
- Plan for future expansions efficiently
🔌 Included: Cable Sizing & Voltage Drop Analysis
As part of Load Flow Analysis, we perform Cable Sizing and Voltage Drop Assessment to ensure that conductors are adequately rated for the connected loads. This helps prevent overheating, minimizes energy losses, and maintains voltage levels within permissible limits at every node.
Purpose:
- To select correct cable sizes based on load and distance
- To ensure voltage remains within design tolerance
- To avoid thermal stress and reduce power loss
Benefit: Helps identify under- or over-voltage areas, overloaded equipment, and inefficiencies.
3. Short Circuit Analysis
Simulates fault conditions (line-to-line, line-to-ground, etc.) to calculate the fault current magnitudes.
Purpose: To determine interrupting ratings for circuit breakers and fuses.
Benefit: Prevents equipment damage and ensures safety during fault scenarios.
4. Harmonic Analysis
Detects the presence of harmonics caused by nonlinear loads (like VFDs, UPS, and inverters).
Purpose: To identify harmonic distortion levels and their effect on sensitive equipment.
Benefit: Reduces overheating, mis operation, and energy loss.
5. Transient Stability Study
Evaluates the system’s dynamic behaviour during and after disturbances like faults or switching events.
Purpose: To ensure that generators and large motors remain synchronized and stable.
Benefit: Prevents blackouts and cascading system failures.
6. Arc Flash Hazard Analysis
Calculates incident energy levels and determines arc flash boundaries to protect personnel.
Purpose: To comply with electrical safety standards and PPE recommendations (IEEE 1584 / NFPA 70E).
Benefit: Reduces risk of injury and improves workplace safety protocols.
7. Earthing Study
We conduct engineering analyses that evaluate how effectively an electrical system can safely discharge fault currents into the ground. These studies ensure personnel safety, protect equipment, and maintain compliance with electrical safety standards.
Purpose: To verify that fault currents are safely dissipated into the earth, minimizing shock hazards, equipment damage, and operational risk.
Benefits: Ensure personnel safety and Protect equipment and infrastructure
8. Motor Starting Analysis
Simulates voltage drops and system impact due to motor inrush current.
Purpose: To determine the starting method and system capacity to handle large motors.
Benefit: Ensures reliable starting without compromising voltage quality.
9. Power Factor & Reactive Power Study
Identifies power factor levels and recommends compensation techniques.
Purpose: To improve energy efficiency and avoid utility penalties.
Benefit: Optimized usage of electrical power and reduced costs.
