Expert Switchgear Commissioning
Watts & Ergonās MV/HV switchgear commissioning in UAE includes protection relay configuration. Expert Switchgear Commissioning is a critical, multi-stage validation process that ensures your electrical distribution assets are safe, reliable, and fully compliant with international standards such as IEC 62271 and local utility regulations (DEWA/ADDC). Our expert-led approach transitions the system from a static installation to a dynamic, “energization-ready” state through rigorous diagnostic testing, including Contact Resistance Measurement (CRM), Insulation Resistance (IR) verification, and sophisticated Protection Relay Coordination. We utilize advanced primary and secondary injection testing to simulate fault conditions, ensuring that breakers and relays trip with millisecond precision to protect your downstream equipment. By integrating thermal imaging and SF6 gas quality analysis for High Voltage (HV) units, we provide a definitive “Certified for Service” report that minimizes the risk of arc-flash incidents, reduces unplanned downtime, and guarantees the long-term operational integrity of your power infrastructure.

Our pre-installation support ensures that your electrical system is legally compliant, technically sound, and cost-effective.
Our Pre-Installation Engineering Services
1. Load Schedules
We calculate total connected load and maximum demand to ensure panels and cables are perfectly sized, preventing overheating or nuisance tripping.
2. Protection Coordination
Advanced simulations ensure “selectivity”āif a fault occurs, only the local breaker trips, preventing total building blackouts.
3. Single Line Diagrams (SLD) & Shop Drawings
Our engineers draft detailed blueprints that serve as the technical foundation for your network. These drawings include specifications for breakers, busbars, and protection relays.
4. Utility Approval & NOC Coordination
We manage technical submissions to local authorities to meet specific standards:
- DEWA / ADDC: Compliance for metering cabinets and transformer rooms.
- Civil Defence (DCD): Integration of fire-rated cables and emergency power systems.
Why Professional Design Matters
| Benefit | How it Works |

| Speed | Accurate shop drawings prevent errors and costly “re-works” during installation. |
MV Switchgear Commissioning in the UAE
Expert validation for 11kV, 22kV, and 33kV Power Distribution Infrastructure.
In the UAE, Medium Voltage (MV) switchgear commissioning is a critical process governed by international standards (IEC 62271) and local utility regulations from DEWA, ADDC, and Etihad WE. Because MV systems handle immense power, this is the final “fail-safe” before energization.
1. Pre-Commissioning (Cold Testing)
Physical and electrical integrity must be verified before any power is introduced to the system.
Checking for transport damage, busbar bolt torque marks, and ensuring the IP rating remains intact.
Using a 5kV Megger to ensure zero leakage between phases or to the earth grounding system.
Measuring resistance across breaker poles (micro-ohms) to prevent overheating and potential fire risks.
2. Protection & Control Testing
This phase verifies the “intelligence” of the switchgear to ensure it reacts correctly during a fault.
- Secondary Injection Testing: Using kits like Omicron to confirm protection relays correctly identify overcurrent or earth faults.
- Primary Injection Testing: Verifying the entire protection chain from the physical busbars through to the digital relay.
- CT/VT Ratio & Polarity: Ensuring transformers accurately “step down” current for meters and protection logic.
3. Operational Safety Checks
For Gas Insulated Switchgear (GIS), we also perform SF6 Gas Quality & Pressure checks to ensure no leaks are present in the encapsulated chambers.
4. Technical Compliance Overview
| Test Category | Standard Requirement | Importance |
|---|---|---|
| Dielectric Test | Power Frequency Withstand | Prevents high-voltage flashovers. |
| Timing Test | Open/Close Speed | Ensures the breaker quenches arcs instantly. |
| Relay Coordination | Selectivity Study | Prevents minor faults from causing total blackouts. |
