DET3 Contractor Series
3-Terminal Earth/Ground Resistance Testers
DESCRIPTION
Megger’s already popular 3-terminal ground testing
instrument family includes the following models:
Model
DET3TD
DET3TC
start testing in one package. Optional terminal adapters
are available for acceptance of a variety of test leads.
Using ART method with the DET3TC
to test commercial ground without
disconnecting the system
For basic requirements it provides digital
ground testing and bond testing capabilities
The revolutionary new model with the
capability of testing on-site grounds without
disconnecting the utility connection.
Description
delivered in a tough
polypropylene carry case
– everything you need to
The DET3TC includes a
current measuring function
for ART (Attached Rod
Technique) testing
capabilities. With this
added function, on-site
grounds can be tested
separately without having
to remove the utility
connection (as explained
further in this document).
The complete kit of
instrument, test leads,
stakes, batteries and
calibration certificate is
All models are rated to IP54, making them truly outdoor
instruments. They are designed to meet stringent safety
standards and are rated CAT IV 100V. The ground testers
have been designed to be easy to use – a large selector
switch makes selection of 2 or 3 pole tests easy with
gloved hands – and the design makes the fitting of
shorting links to perform 2-pole tests a thing of the past. A
large, clear, easy to read LCD and thumb-sized test button
also make the instruments particularly well suited to the
outdoor conditions of ground testing. In addition to this
ease of use feature, the ground tester automatically checks
the connection and conditions of the P spike, C spike, and
also the level of ground noise, indicating the status on the
display. The instruments also include a voltmeter to enable
measurement of ground voltage. They can measure
resistance from 0.01 ohms to 2 kΩ. Also, to allow accurate
testing in noisy environments, the instruments are capable
of rejecting noise up to 40V peak to peak.
The Megger ground testers are powered by eight AA
batteries which are widely available and also give
excellent testing time – the status of these batteries is
given by a bar graph on the LCD, allowing the operator to
decide when to change the batteries before they expire.
By using the optional ICLAMP with the DET3TC, the user
can augment the traditional fall-of-potential measurement
method with ART (Attached Rod Technique), which allows
electrode testing without disconnection and also leakage
current measurements down to 0.5 mA.
