Portable earth tester

May 2014 Electrical Power & Protection

Megger’s DET4TC2 is a portable, lightweight device used for easy measurement of earthing. It is capable of performing 2, 3 and 4 point testing with variable frequency, attached rod technique, stakeless testing, leakage current and ground noise voltage measurements.

The DET4TC2 is simple to use, with an interface that is easy to understand. To switch between tests, the user simply turns the rotary dial to choose the required test type. The frequency of the test can then be chosen to switch between 94, 105, 111 and 128 Hz modes and can then change the overall voltage of the test procedure between 25/50 V. A button for activating a backlight on the LCD screen allows measurements to be seen in poor lighting conditions.

By use of ICLAMP, a Megger accessory which is sold separately, the Megger DET4TC2 is able to use ART, which allows electrode testing without connection and leakage current measurements. The VCLAMP accessory performs true stakeless measurements, ideal for areas where it is impossible to use driving stakes.

The overall resistance range of this device is between 0,01 Ω and 200 kΩ, the ground noise voltage range is between 1 and 100 V and ground current measurements are between 1 and 20 A. To maintain the accuracy of test results, the DET4TC2 also includes noise evaluation and rejection, and the device will automatically reject noise voltages of 40 V peak to peak to minimise the overall effect electrical noise can have on test results. This device is rated to 100 V CAT IV and is in compliance with IEC 61557-5.
