Test & Commissioning
Support
Understanding standards and regulations, adhering to manufacturer recommendations, and implementing a comprehensive test and commissioning plan are essential steps to ensure the successful completion and reliable operation of your project.
• Inspection test plan (ITP) specification, review
• Witnessing installation tests such as insulation resistance test, VLF/60Hz (or near-power frequency) withstand test, jacket integrity test, and visual inspection
• Fault location and repair supervision.
• Inspection test plan (ITP) specification, review, or revision based on IEEE 400, IEEE 400.1, IEEE 400.2, IEEE 400.3, IEEE 400.4, IEEE 400.5, IEC 60840, IEC 62067 or utility-specific standard
• Witnessing and reviewing commissioning tests such as insulation resistance test, VLF/60Hz (or near-power frequency) withstand test, and partial discharge test
• Jacket integrity test, manhole grounding test, splice SVL test and link box verification
• TDR , OTDR, Conductor resistance, Sheath resistance, zero-sequence impedance measurement
• Termination surge arrester test
• Monitoring system commissioning check
• Partial discharge localization analysis
• Termination corona PD and Infrared thermography analysis
• Soak test monitoring.
• Inspection test plan (ITP) for in-service aged cables
• Dissolve Gas Analysis (DGA) of oil-filled cables
• Diagnostics tests such as online/offline PD, VLF Tan-Delta, TDR, Capacitance and Dissipation Factor (C&DF)
• Oil Leak Detection (Injecting dyes, radioactive material, tracer gases, odorants, acoustic emission, radar, infrared)
• Frequency Domain Spectroscopy (FDS), Polarization/Depolarization Current (PDC)
• Broadband Impedance Spectroscopy (LIRA).
