Protection Coordination & Relay Engineering

Protection Coordination & Relay Engineering

Selective and Reliable Protection Schemes We provide protection coordination and relay engineering services to ensure faults are cleared selectively and reliably, without unnecessary disruption to healthy parts of the system. Our work covers both greenfield installations and existing networks where protection systems have evolved over time. In practice, this involves reviewing protection philosophies, relay settings, and coordination margins across upstream and downstream devices to maintain system integrity.

Our Technical Toolkit

  • Protection coordination and selectivity studies
  • Relay settings review and verification
  • Development or review of protection philosophies
  • Assessment of switchgear and protection schemes

  • Electrical Drafting
  • Project Scheduling

Our Specialized Services

Our Specialized Services We ensure your electrical assets are protected through rigorous analysis and alignment with global standards.

1. What services does Technical Solution & Services (TSS) provide?

TSS provides independent power system engineering and consulting services, including power system studies, protection engineering, primary and detailed electrical design, risk and feasibility assessments, and project and contract management for industrial and utility clients.

2. What types of industries does TSS serve?

TSS supports a wide range of industries, including: Mining and minerals processing Oil and gas (onshore and offshore) Power utilities and transmission networks Water and desalination facilities Heavy industrial and manufacturing plants Our services are tailored to the operational and regulatory requirements of each sector.

3. What is a power system study and why is it required?

A power system study evaluates the performance, safety, and reliability of an electrical network under normal and fault conditions. These studies are essential to: Ensure safe operation of electrical equipment Comply with international standards and regulations Identify system limitations and risks Support informed design and operational decisions Typical studies include load flow, short circuit, protection coordination, arc flash, and stability analysis.

4. Why is arc flash hazard analysis important?

Arc flash hazard analysis assesses the risk of thermal energy exposure during electrical faults. It is critical for: Protecting personnel safety Defining appropriate personal protective equipment (PPE) Ensuring compliance with electrical safety standards Reducing the likelihood and severity of electrical incidents TSS performs arc flash studies in accordance with applicable IEC and IEEE guidelines.

5. Which engineering standards does TSS follow?

TSS delivers services in alignment with internationally recognized standards, including: IEC standards IEEE standards Client-specific technical and safety requirements All work is performed using industry best practices and documented engineering methodologies.
