Megger 1012-521 DET4TC2 + ETK50C
The Megger DET4TC2 is designed for extended temperature range use with an IP54-rated enclosure making it a genuine outdoor instrument. The instrument provides all the functions required for ground system testing: variable frequency 2 pole, 3 pole, 4 pole, Attached Rod Technique (ART), stakeless, leakage current, and ground noise voltage measurement.
The instrument is easy to use with a large rotary selector switch and one-press test button, both of which permit operation with gloved hands. Unlike some instruments, the design negates the need for a shorting link when making two pole measurements. There are no hidden functions with the instrument: clearly labelled auxiliary controls are used to select the test frequency (94 Hz, 105 Hz, 111 Hz, and 128 Hz), output voltage (50 V or 25 V where local standards apply), and to switch the backlight on or off.
The clear, easy-to-read display provides excellent contrast and viewing angle making the instrument ideally suited to outdoor use. The display is backlit, extending the operational environment of the instrument to cable cellars and other dark locations.
The instrument offers a wide measurement range of 0.01 Ω a to 200 kΩ, ground noise voltage measurement from 1 V to 100 V, and ground current from 1 mA to 20 A. Accurate results can be obtained in electrically noisy environments since the instrument is capable of rejecting noise voltages of 40 V peak to peak and the user can select different test frequencies to minimise the effect of interference.
The DET4TC2 digital ground tester is powered by 8 AA batteries which are widely available and deliver excellent testing time, the battery status is displayed using a bar graph.
The Megger DET4TC2 complies with stringent safety standards and is rated to 100 V CAT IV. They also have selectable 25 V or 50 V output for compliance with IEC 61557-5.
The Megger 1012-521 delivers the DET4TC2 and the ETK50C. The ETK50C kit includes 50m Earth Test Cables, Spikes & Clamps.
