Cable Testing: Insulation Resistance & VLF

Overview

Insulation Resistance (Megger) and VLF cable testing, with results recorded against every cable in a live completions database.

Cable testing is the step that proves an installation is ready to energize. Sitewide provides Insulation Resistance (Megger Test) and VLF testing as part of electrical pre-commissioning, with the test equipment, technicians and documentation to keep it moving.

Testing we provide

  • Insulation Resistance (Megger) testing
  • VLF testing of medium-voltage cable
  • Continuity, phase-rotation and point-to-point testing on LV circuits
  • Grounding and bonding verification

Results you can trace

Cable schedules are loaded straight into our completions database, so each result is logged against its cable, failures become tracked punchlist items, and the owner can see test status live.
