Why Ground Testing Matters – And How the Fluke 1623/1625 Solves the Problem

At GIL Automation, we’ve seen it firsthand — an entire electrical system can be perfect on paper, yet fail catastrophically in the field due to one invisible fault: poor grounding.

From power substations to control panels, telecom towers, and tank farms, the earth is your final return path. If that connection is weak, inconsistent, or unverified, everything above it is vulnerable — people, equipment, operations, and investment.

Without a low-impedance earth path, your protection devices (like surge arrestors, lightning rods, RCDs, or cathodic protection) may not operate when they should.
And when a fault occurs — like a lightning strike or insulation failure — the excess current has nowhere safe to go.

The result?

  • Electrical fires
  • Equipment failure
  • PLC & DCS malfunctions
  • Data loss
  • Voltage instability
  • Personnel hazard

And it’s not just theory. Across Nigeria, engineers quietly fight issues caused by untested or degraded grounding systems. They don’t always make the news, but we know the pain points.

Designed for engineers, trusted by technicians — the Fluke 1623 and 1625 are the go-to tools for accurate, repeatable ground resistance and soil resistivity testing across every industry. See key specifications below.

Key Technical Features:

  • 3- & 4-pole testing: Accurately measure ground loop resistance
  • Selective testing: Isolate individual grounds in multi-system grids
  • Stakeless method: Test without driving auxiliary rods (using clamps)
  • Soil resistivity mode: Design effective grounding systems from scratch
  • IP56 rating: Built for rain, dust, and the real world
  • Safety-rated to CAT II 300V

CROSS-INDUSTRY RELEVANCE
