Measurement

Soil resistivity & rod spacing

Never Trust One Soil Resistivity Test.

New Cairo3 min

Connections & materials

The hidden failure of grounding connections

A Grounding System Is Only as Reliable as Its Weakest Connection.

Hurghada3 min

Connections & materials

When a closed weld breaks the current path

The weld looked closed. The current path was not.

New Administrative Capital3 min

Measurement

The grid was blamed. The test was wrong.

The earth grid was blamed. The test geometry was wrong.

Upper Egypt3 min

Measurement

An open loop in rocky ground

OPEN LOOP did not mean an open earthing system.

New Minya3 min

Measurement

Solar earthing & tracker control

One test method cannot describe every part of a solar plant.

Benban, Aswan3 min

Measurement

A low reading can hide a poor earth

The meter showed 1 Ω. The isolated grid was actually far worse.

Obour3 min

Earthing & bonding

Separate earths. Different potentials.

Separate earths created separate potentials.

New Administrative Capital3 min

Critical systems

Completing the Medical IT system

An isolating transformer alone does not make a Medical IT system complete.

Hospital ICU3 min

Earthing & bonding

Soil cannot replace a protective conductor

Soil is not a substitute for a designed protective conductor.

Sheikh Zayed3 min

Measurement

A calibrated tester with damaged leads

The tester was calibrated. The test setup was not healthy.

Residential project3 min

Measurement

The right instrument. The wrong range.

The wrong range can make a good instrument produce bad engineering.
