Earthing, Clamping, and the Limits of Induction
Where the earth goes and why it matters, connection angles at 45 and 90 degrees, double ended connections, and an honest account of what induction will and will not do for you.
Watch 1:26:46 →High End EM Locators: RD8000, RD8100 and vLocPro2
The top end of the locating kit and what it does that a basic set cannot: signal strength and current measurement, what those numbers tell you when you are stood over a line, and the pipeline corrosion work these instruments are built for. Pete Ashcroft and Steve, in full.
Watch 3:44:52 →How a Utility Network Works, and What the Plans and Marker Plates Tell You
How the supply actually gets from the power station to a house, the cable types you meet on the way including old Hessian, and how to read a stats plan and a utility marker plate for what is really under your feet.
Watch 1:48:39 →Overlaid and Compiled Plans: Why They Invite Assumptions
What a compiled or overlaid drawing hides that the individual stats plans show. Pete Ashcroft on why one tidy drawing of everything is more dangerous than several awkward ones.
Watch 8:52 →Connection Angles and Where the Earth Goes
Connection geometry: at 90 degrees half the signal goes each way. Angling the connection and the earth toward the target changes what you get.
Watch 2:53 →Depth Readings, and What They Mean on a Pipe
Taking a depth reading properly, and the caveat that matters on a pipe: what the number actually refers to.
Watch 0:58 →The Earth Spike, the Signal Clamp, and the Appliance Safety Check
The earth spike making the CAT more accurate, the signal clamp around a pipe or cable, and the safety check with the customer first.
Watch 1:22 →Tracing Pipes vs Cables: Where Signal Leaks
A metal pipe leaks signal along its length; a cable holds it until the insulation fails. Why the two trace differently and how to read each one.
Watch 3:37 →Water Mains from the Hydrant, and the Earth Lead Tone
Tracing the water main by connecting at the hydrant, and what the earth lead does and does not do to the tone when you connect it.
