On-Site Energization & Assisted Operation

The Severe Risk of Inadequate Testing

Wiring mistakes, reversed CT/VT polarities, or unverified tripping schemes result in catastrophic equipment damage, arc flash incidents, and costly commercial delays during substation start-up.

Our Systematic Field Verification

We execute systematic, auditable electrical commissioning protocols: visual inspection, insulation resistance tests, dynamic secondary injection, and point-to-point verification to SCADA to ensure every protection element acts as designed at first energization.

  • Dynamic relay testing simulating real transient fault waveforms.
  • Physical trip testing on breakers verifying all lockout and interlock schemes.
  • Comprehensive technical test reports with traceable calibration certificates.
  • On-site standby and technical supervision during live energization.
TECHNICAL DELIVERABLES

Technical Testing Scope & Commissioning Deliverables

Protecting physical assets and ensuring regulatory compliance during energization

Secondary Current & Voltage Injection

Metrological testing of numerical relays using calibrated hexaphase OMICRON CMC 356 sets, verifying pickup values, operating times, and directional impedance characteristics.

Key Engineering Deliverables:

  • Overcurrent curve verification (50/51, 50N/51N)
  • Distance protection (21) and transformer differential (87) zone testing
  • CT saturation checks, polarity verification, and ratio validation
  • Detailed test reports with generated oscillograms and calibration data

Trip Matrix & Functional Interlocking

Physical validation of the complete control chain: from the IED digital output contact to breaker opening/closing coils and associated disconnectors.

Key Engineering Deliverables:

  • Comprehensive cause-and-effect trip matrix testing
  • Master trip and lockout relay (ANSI 86) operation checks
  • Breaker failure (50BF) and auto-reclosing simulation
  • Inter-bay hardware and software interlocking validation

FAT and SAT Acceptance Testing

Engineering leadership in Factory Acceptance Testing (FAT) with panel integrators and Site Acceptance Testing (SAT) at the project facility.

Key Engineering Deliverables:

  • Panel wiring, layout, and schematic verification at the factory
  • Client-approved standardized test procedure sign-offs
  • Point-to-point digital and analog verification to SCADA HMIs
  • Systematic punch list management and definitive resolution

Initial Energization & Assisted Operation

Senior field engineers on-site during initial substation switching operations, monitoring electrical quantities and supporting operations personnel.

Key Engineering Deliverables:

  • No-load measurements (voltage, phase sequence, synchronism check)
  • Phasor diagram verification under initial live load current
  • Real-time verification of power flow direction and differential currents
  • Contingency support and monitoring during assisted initial operation
