Ground resistance testing covers the testing of earth electrodes and the measurement of soil resistivity. The instrument requirements depend on the range of applications.
Megger offers top end systems for design and soil surveys as well as tough easy to use testers for field engineers. We have tried to make the testers self checking as much as we can, to allow you to concentrate on collating and understanding the results.

Battery testing equipment
Megger engineeringWith the increasing dependency of back up systems on battery strings, and the escalating cost of replacing batteries, instrumentation and software systems that can measure, trend and manage the life-cycle of cells is a cost effective option.
There are two methodologies for testing batteries. The first, impedance testing is an on line test and can be performed frequently to identify individual weak cells before they fail. The second, battery discharge test is, normally, an off-line test and tests the actual output of the whole battery under load conditions. This will show what will actually happen if the battery is required to take the load. Most battery systems are floating and have earth leakage monitors and trips if there is an earth fault. The Battery Ground Fault Tracer allows you to trace a faulty circuit easily in a complex floating system.
Low resistance ohmmeters
Megger engineering
From Megger, these highly accurate, easy to operate instruments measure resistance with resolution as fine as 0.1 micro-ohm. Digital micro-ohmeters and DLROs measure contact resistance of switch and circuit breakers, aircraft frame bonds, and rail and pipeline bonds just to name a few of the applications. Megger has models available for testing using test currents from 0.5 mA to 200 amps covering a multitude of applications that require precise low-resistance measurements.
