DESCRIPTION

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 USB interface cable and is compatible with Megger

Download Manager Software (included) allowing further

analysis and storage of data.

APPLICATION

The DET10C and 20C have a variety of applications

including:

I

Use to measure resistance and continuity of grounding

loops around pads and buildings.

I

Use on multi-grounded systems without disconnecting

the ground rod/stake under test.

I

Use to measure leakage current flowing to ground or

circulating in ground systems.

I

Use on cell towers, RF transmitters and

telecommunications sites.

I

Use to inspect and verify lightning protection systems.

I

Use on a variety of consumer installations, including

pools, spas, etc.

I

Measure shield leakage current to ground for shield

continuity checks
