The Megger models DET10C and 20C measure
earth/ground resistance and current flow using clamp-on technology.
The instruments induce a test current into the
system without the need to disturb existing connections. Either
unit is a useful addition to the more traditional methods of earth/ground
resistance testing that may require disconnection and the use
of stakes or ground rods. Simply clamp around the conductor or
stake/rod and measure the resistance to ground fast and accurately.
The DET10C and 20C can also be used to measure earth/ground resistance
in multiple loop installations without disconnecting the earth
or ground. This allows the user to perform the test quickly and
easily in total safety, with the added convenience of having a
single point of measurement to read the earth/ground resistance.
Each instrument also provides a true RMS current measurement
reading to better indicate potential measurement problems and
provide a useful overview of the dynamics of the general earth/ground
system.
The units are rugged, compact and have configurable audible alarms.
They also feature auto shutdown (which is also configurable),
data storage and self calibration on power-up, and are supplied
with a calibration loop – all contained in a rugged carry
case. The DET20C also comes with a RS232 interface cable and is
compatible with Megger Download Manager Software (included) allowing
further analysis and storage of data.
