Our Approach

Systematic from pre-checks to energization.

Every project is approached with clear test procedures, documentation and safety controls.

01

Review & Planning

Review drawings, protection settings, test requirements, equipment data and project scope.

02

Pre-Commissioning

Visual inspection, wiring verification, insulation and equipment-specific preliminary checks.

03

Functional Testing

Control, interlock, indication, trip-close and protection scheme functional verification.

04

Protection Testing

Secondary injection, pickup, timing, characteristic and scheme verification as applicable.

05

Integrated Checks

End-to-end logic, trip paths, alarms, interlocks and system interfaces are checked before energization.

06

Reports & Handover

Test results, observations and commissioning documentation are compiled for project handover.
